This is an article detailing different methods of Arch/Windows coexistence.

Important information

Windows UEFI vs BIOS limitations

Microsoft imposes limitations on which firmware boot mode and partitioning style can be supported based on the version of Windows used:

Note: The following points only list configurations supported by the Windows Setup even though Windows itself may still work on these unsupported configurations. A good example of this is Windows 11 which still works on a BIOS/MBR configuration once the Windows Setup check is bypassed.

• Windows 8/8.1 and 10 x86 32-bit support booting in IA32 UEFI mode from GPT disk only, OR in BIOS mode from MBR disk only. They do not support x86_64 UEFI boot from GPT/MBR disk, x86_64 UEFI boot from MBR disk, or BIOS boot from GPT disk. On market, the only systems known to ship with IA32 (U)EFI are some old Intel Macs (pre-2010 models?) and Intel Atom System-on-Chip (Clover trail and Bay Trail) Windows Tablets, which boot ONLY in IA32 UEFI mode and ONLY from GPT disk.
• Windows 8/8.1 and 10 x86_64 versions support booting in x86_64 UEFI mode from GPT disk only, OR in BIOS mode from MBR disk only. They do not support IA32 UEFI boot, x86_64 UEFI boot from MBR disk, or BIOS boot from GPT disk.
• Windows 11 only supports x86_64 and a boot in UEFI mode from GPT disk.

In case of pre-installed Systems:

• All systems pre-installed with Windows XP, Vista or 7 32-bit, irrespective of Service Pack level, bitness, edition (SKU) or presence of UEFI support in firmware, boot in BIOS/MBR mode by default.
• MOST of the systems pre-installed with Windows 7 x86_64, irrespective of Service Pack level, bitness or edition (SKU), boot in BIOS/MBR mode by default. Very few late systems pre-installed with Windows 7 are known to boot in x86_64 UEFI/GPT mode by default.
• ALL systems pre-installed with Windows 8/8.1, 10 and 11 boot in UEFI/GPT mode. Up to Windows 10, the firmware bitness matches the bitness of Windows, ie. x86_64 Windows boot in x86_64 UEFI mode and 32-bit Windows boot in IA32 UEFI mode.

An easy way to detect the boot mode of Windows is to do the following[1]:

• Boot into Windows
• Press Win+R keys to start the Run dialog
• In the Run dialog type msinfo32 and press Enter
• In the System Information windows, select System Summary on the left and check the value of BIOS mode item on the right
• If the value is UEFI, Windows boots in UEFI/GPT mode. If the value is Legacy, Windows boots in BIOS/MBR mode.

In general, Windows forces type of partitioning depending on the firmware mode used, i.e. if Windows is booted in UEFI mode, it can be installed only to a GPT disk. If Windows is booted in Legacy BIOS mode, it can be installed only to an MBR disk. This is a limitation enforced by Windows Setup, and as of April 2014 there is no officially (Microsoft) supported way of installing Windows in UEFI/MBR or BIOS/GPT configuration. Thus Windows only supports either UEFI/GPT boot or BIOS/MBR configuration.

Tip: Windows 10 version 1703 and newer supports converting from BIOS/MBR to UEFI/GPT using MBR2GPT.EXE.

Such a limitation is not enforced by the Linux kernel, but can depend on which boot loader is used and/or how the boot loader is configured. The Windows limitation should be considered if the user wishes to boot Windows and Linux from the same disk, since installation procedure of boot loader depends on the firmware type and disk partitioning configuration. In case where Windows and Linux dual boot from the same disk, it is advisable to follow the method used by Windows, ie. either go for UEFI/GPT boot or BIOS/MBR boot. See https://support.microsoft.com/kb/2581408 for more information.

Boot loader UEFI vs BIOS limitations

Most of the Linux boot loaders installed for one firmware type cannot launch or chainload boot loaders of the other firmware type. That is, if Arch is installed in UEFI/GPT or UEFI/MBR mode in one disk and Windows is installed in BIOS/MBR mode in another disk, the UEFI boot loader used by Arch cannot chainload the BIOS installed Windows in the other disk. Similarly if Arch is installed in BIOS/MBR or BIOS/GPT mode in one disk and Windows is installed in UEFI/GPT in another disk , the BIOS boot loader used by Arch cannot chainload UEFI installed Windows in the other disk.

The only exceptions to this are GRUB in Apple Macs in which GRUB in UEFI mode can boot BIOS installed OS via appleloader command (does not work in non-Apple systems), and rEFInd which technically supports booting legacy BIOS OS from UEFI systems, but does not always work in non-Apple UEFI systems as per its author Rod Smith.

However if Arch is installed in BIOS/GPT in one disk and Windows is installed in BIOS/MBR mode in another disk, then the BIOS boot loader used by Arch can boot the Windows in the other disk, if the boot loader itself has the ability to chainload from another disk.

Note: To dual-boot with Windows on same disk, Arch should follow the same firmware boot mode and partitioning combination used by the Windows installation.

Windows Setup creates a 100 MiB EFI system partition (except for Advanced Format 4K native drives where it creates a 300 MiB ESP), so multiple kernel usage is limited. Workarounds include:

• If you are installing Windows from scratch, you can dictate the size of the EFI system partition during installation. See #The EFI system partition created by Windows Setup is too small
• Mount ESP to /efi and use a boot loader that has file system drivers and is capable of launching kernels that reside on other partitions.
• Reduce the size of the Windows partition and replace the existing ESP with a new, larger one.
• Backup and delete unneeded fonts in esp/EFI/Microsoft/Boot/Fonts/ [2].
• Backup and delete unneeded language directories in esp/EFI/Microsoft/Boot/ (e.g. to only keep en-US).
• Use a higher, but slower, compression for the initramfs images making sure to decompress the loadable kernel modules and firmware. E.g.

COMPRESSION="xz"
COMPRESSION_OPTIONS=(-9e)
MODULES_DECOMPRESS="yes"

UEFI Secure Boot

All pre-installed Windows 8/8.1, 10 and 11 systems by default boot in UEFI/GPT mode and have UEFI Secure Boot enabled by default. This is mandated by Microsoft for all OEM pre-installed systems.

Arch Linux install media does not support Secure Boot yet. See Secure Boot#Booting an installation medium.

It is advisable to disable UEFI Secure Boot in the firmware setup manually before attempting to boot Arch Linux. Windows 8/8.1, 10 and 11 SHOULD continue to boot fine even if Secure boot is disabled. The only issue with regards to disabling UEFI Secure Boot support is that it requires physical access to the system to disable secure boot option in the firmware setup, as Microsoft has explicitly forbidden presence of any method to remotely or programmatically (from within OS) disable secure boot in all Windows 8/8.1 and above pre-installed systems

Fast Startup and hibernation

There are two OSs that can be hibernated, you can hibernate Windows and boot Linux (or another OS), or you can hibernate Linux and boot Windows, or hibernate both OSs.

Warning: Data loss can occur if Windows hibernates and you dual boot into another OS and make changes to files on a filesystem (such as NTFS) that can be read and written to by Windows and Linux, and that has been mounted by Windows [3]. Similarly, data loss can occur if Linux hibernates, and you dual boot into another OS etc. Windows may hibernate even when you press shutdown, see section #Windows settings.

For the same reason, if you share one EFI system partition between Windows and Linux, then the EFI system partition may be damaged if you hibernate (or shutdown with Fast Startup enabled) Windows and then start Linux, or hibernate Linux and then start Windows.

ntfs-3g added a safe-guard to prevent read-write mounting of hibernated NTFS filesystems, but the NTFS driver within the Linux kernel has no such safeguard.

Windows cannot read filesystems such as ext4 by default that are commonly used for Linux. These filesystems do not have to be considered, unless you install a Windows driver for them.

Windows settings

Fast Startup is a feature in Windows 8 and above that hibernates the computer rather than actually shutting it down to speed up boot times.

There are multiple options regarding the Windows settings for Fast Startup and hibernation that are covered in the next sections.

• disable Fast Startup and disable hibernation
• disable Fast Startup and enable hibernation
• enable Fast Startup and enable hibernation

The procedure of disabling Fast Startup is described in the tutorials for Windows 8, Windows 10 and Windows 11. In any case if you disable a setting, make sure to disable the setting and then shut down Windows, before installing Linux; note that rebooting is not sufficient.

Disable Fast Startup and disable hibernation

This is the safest option, and recommended if you are unsure about the issue, as it requires the least amount of user awareness when rebooting from one OS into the other. You may share the same EFI system partition between Windows and Linux.

In a Windows command-line shell with administrator privileges:

> powercfg /H off

Disable Fast Startup and enable hibernation

This option requires user awareness when rebooting from one OS into the other.
If you want to start Linux while Windows is hibernated, which is a common use case, then

• you must use a separate EFI system partition (ESP) for Windows and Linux, and ensure that Windows does not mount the ESP used for Linux. As there can only be one ESP per drive, the ESP used for Linux must be located on a separate drive than the ESP used for Windows. In this case Windows and Linux can still be installed on the same drive in different partitions, if you place the ESP used by linux on another drive than the Linux root partition.
• you can not read-write mount any filesystem in Linux, that is mounted by Windows while Windows is hibernated. You should be extremely careful about this, and also consider Automount behaviour.
• If you shut down Windows fully, rather than hibernating, then you can read-write mount the filesystem.

Note: You can avoid this issue for a drive by mounting a drive as an external drive in Windows and ejecting the drive in Windows before hibernating.

Enable Fast Startup and enable hibernation

The same considerations apply as in case «Disable Fast Startup and enable hibernation», but since Windows can not be shut down fully, only hibernated, you can never read-write mount any filesystem that was mounted by Windows while Windows is hibernated.

Note: Windows updates may re-enable Fast Startup, as reported in [4]^{[dead link 2024-07-30 ⓘ]}.

Windows filenames limitations

Windows is limited to filepaths being shorter than 260 characters.

Windows also puts certain characters off limits in filenames for reasons that run all the way back to DOS:

• < (less than)
• > (greater than)
• : (colon)
• " (double quote)
• / (forward slash)
• \ (backslash)
• | (vertical bar or pipe)
• ? (question mark)
• * (asterisk)

These are limitations of Windows and not NTFS: any other OS using the NTFS partition will be fine. Windows will fail to detect these files and running chkdsk will most likely cause them to be deleted. This can lead to potential data-loss.

NTFS-3G applies Windows restrictions to new file names through the windows_names option: ntfs-3g(8) § Windows_Filename_Compatibility (see fstab).

Installation

The recommended way to set up a Linux/Windows dual booting system is to first install Windows, only using part of the disk for its partitions. When you have finished the Windows setup, boot into the Linux install environment where you can create and resize partitions for Linux while leaving the existing Windows partitions untouched. The Windows installation will create the EFI system partition which can be used by your Linux boot loader. If you are installing Windows from scratch, do note that the EFI System partition created by Windows Setup will be too small for most use cases. See #The EFI system partition created by Windows Setup is too small.

Windows before Linux

BIOS systems

Using a Linux boot loader

You may use any multi-boot supporting BIOS boot loader.

Using the Windows Vista/7/8/8.1 boot loader

This section explains how to:

• install a linux boot loader on a partition instead of the MBR;
• copy this boot loader to a partition readable by the Windows boot loader;
• use the windows boot loader to start said copy of the linux boot loader.

Note: Some documents state that the partition being loaded by the Windows boot loader must be a primary partition but usage of an extended partition has been documented as working.

• When installing the boot loader, install it on your /boot partition rather than the MBR. For details on doing this with GRUB, see GRUB/Tips and tricks#Install to partition or partitionless disk, for Syslinux, see the note at Syslinux#Manually, for LILO see LILO#Install to partition or partitionless disk.

• Make a copy of the VBR:

  dd if=/dev/disk of=/path/to/linux.bin bs=512 count=1

  where /dev/disk is the path of the partition on which your boot loader is installed and /path/to/ is the mounted filesystem on which you want the copy to be readable by the Windows boot loader.

• On Windows, the linux.bin file should now be accessible. Run cmd with administrator privileges (navigate to Start > All Programs > Accessories, right-click on Command Prompt and select Run as administrator):

  bcdedit /create /d "Linux" /application BOOTSECTOR

  BCDEdit will return a UUID for this entry. This will be referred to as UUID in the remaining steps.

  bcdedit /set UUID device partition=c: (or the drive letter on which linux.bin is kept)
  bcdedit /set UUID path \path\to\linux.bin
  bcdedit /displayorder UUID /addlast
  bcdedit /timeout 30

On reboot, both Windows and Linux should now show up in the Windows boot loader.

Note: On some hardware, the Windows boot loader is used to start another OS with a second power button (e.g. Dell Precision M4500).

For more details, see https://www.iceflatline.com/2009/09/how-to-dual-boot-windows-7-and-linux-using-bcdedit/

UEFI systems

If you already have Windows installed, it will already have created some partitions on a GPT-formatted disk:

• a Windows Recovery Environment partition, generally of size 499 MiB,
• an EFI system partition with a FAT32 filesystem, containing the Windows Boot Manager,
• a Microsoft Reserved Partition, generally of size 128 MiB,
• a Microsoft basic data partition with a NTFS filesystem, which corresponds to C:,
• potentially system recovery and backup partitions and/or secondary data partitions (corresponding often to D: and above).

Using the Disk Management utility in Windows, check how the partitions are labelled and which type gets reported. The Reserved Partition may not be visible in the Disk Management utility in which case it can be identified using diskpart in windows cmd. This will help you understand which partitions are essential to Windows, and which others you might repurpose. The Windows Disk Management utility can also be used to shrink Windows (NTFS) partitions to free up disk space for additional partitions for Linux.

Warning: The first 4 partitions in the above list are essential, do not delete them.

You can then proceed with partitioning, depending on your needs. The boot loader needs to support chainloading other EFI applications to dual boot Windows and Linux. An additional EFI system partition should not be created, as it may prevent Windows from booting.

Note: It only appears when Linux is installed on the second hard disk and a new EFI system partition is created on the second hard disk.

Simply mount the existing partition.

Computers that come with newer versions of Windows often have Secure Boot enabled. You will need to take extra steps to either disable Secure Boot or to make your installation media compatible with secure boot (see above and in the linked page).

Linux before Windows

Even though the recommended way to set up a Linux/Windows dual booting system is to first install Windows, it can be done the other way around. In contrast to installing Windows before Linux, you will have to set aside a partition for Windows, say 40GB or larger, in advance. Or have some unpartitioned disk space, or create and resize partitions for Windows from within the Linux installation, before launching the Windows installation.

UEFI firmware

Windows will use the already existing EFI system partition.
Follows an outline, assuming Secure Boot is disabled in the firmware.

1. Boot into windows installation. Watch to let it use only the intended partition, but otherwise let it do its work as if there is no Linux installation.
2. Follow the #Fast Startup and hibernation section.
3. Fix the ability to load Linux at start up, perhaps by following #Cannot boot Linux after installing Windows. It was already mentioned in #UEFI systems that some Linux boot managers will autodetect Windows Boot Manager. Even though newer Windows installations have an advanced restart option, from which you can boot into Linux, it is advised to have other means to boot into Linux, such as an arch installation media or a live CD.

Windows 10 with GRUB

The following assumes GRUB is used as a boot loader (although the process is likely similar for other boot loaders) and that Windows 10 will be installed on a GPT block device with an existing EFI system partition (see the «System partition» section in the Microsoft documentation for more information).

Create with program gdisk on the block device the following three new partitions. See [5] for more precise partition sizes.

Create NTFS file systems on the new Microsoft basic data and Windows RE (recovery) partitions using the mkntfs program from package ntfs-3g.

Reboot the system into a Windows 10 installation media. When prompted to install select the custom install option and install Windows on the Microsoft basic data partition created earlier. This should also install Microsoft EFI files in the EFI system partition.

After installation (set up of and logging into Windows not required), reboot into Linux and generate a GRUB configuration for the Windows boot manager to be available in the GRUB menu on next boot.

Troubleshooting

Couldn’t create a new partition or locate an existing one

See #Windows UEFI vs BIOS limitations.

Cannot boot Linux after installing Windows

See Unified Extensible Firmware Interface#Windows changes boot order.

Restoring a Windows boot record

By convention (and for ease of installation), Windows is usually installed on the first partition and installs its partition table and reference to its boot loader to the first sector of that partition. If you accidentally install a boot loader like GRUB to the Windows partition or damage the boot record in some other way, you will need to use a utility to repair it. Microsoft includes a boot sector fix utility FIXBOOT and an MBR fix utility called FIXMBR on their recovery discs, or sometimes on their install discs. Using this method, you can fix the reference on the boot sector of the first partition to the boot loader file and fix the reference on the MBR to the first partition, respectively. After doing this you will have to reinstall GRUB to the MBR as was originally intended (that is, the GRUB boot loader can be assigned to chainload the Windows boot loader).

If you wish to revert back to using Windows, you can use the FIXBOOT command which chains from the MBR to the boot sector of the first partition to restore normal, automatic loading of the Windows operating system.

Of note, there is a Linux utility called ms-sys^AUR that can install MBR’s. However, this utility is only currently capable of writing new MBRs (all OS’s and file systems supported) and boot sectors (a.k.a. boot record; equivalent to using FIXBOOT) for FAT file systems. Most LiveCDs do not have this utility by default, so it will need to be installed first, or you can look at a rescue CD that does have it, such as Parted Magic.

First, write the partition info (table) again by:

# ms-sys --partition /dev/sda1

Next, write a Windows 2000/XP/2003 MBR:

# ms-sys --mbr /dev/sda  # Read options for different versions

Then, write the new boot sector (boot record):

# ms-sys -(1-6)          # Read options to discover the correct FAT record type

ms-sys can also write Windows 98, ME, Vista, and 7 MBRs as well, see ms-sys -h.

Restoring an accidentally deleted EFI system partition

If you have a GPT-partitioned disk and erased (e.g. with mkfs.fat -F32 /dev/sdx) the EFI system partition, you will notice that Windows Boot Manager will either disappear from your boot options, or selecting it will send you back to the UEFI.

To remedy it, boot with a Windows installation media, press Shift+F10 to open the console (or click NEXT > Repair Computer > Troubleshoot… > Advanced > Command Prompt), then start the diskpart utility:

X:\Sources> diskpart
DISKPART> list disk

Select the appropriate hard drive by typing:

DISKPART> select disk number

Make sure that there is a partition of type system (the EFI system partition):

DISKPART> list partition

Select this partition:

DISKPART> select partition number

and assign a temporary drive letter to it:

DISKPART> assign letter=G:

DiskPart successfully assigned the drive letter or mount point.

To make sure that drive letter is correctly assigned:

DISKPART> list vol

 Volume ###  Ltr  Label        Fs     Type        Size     Status     Info
 ----------  ---  -----------  -----  ----------  -------  ---------  --------
 Volume 0     E                       DVD-ROM         0 B  No Media
 Volume 1     C                NTFS   Partition    195 GB  Healthy    Boot
 Volume 2         WINRE        NTFS   Partition    400 MB  Healthy    Hidden
 Volume 3     G                FAT32  Partition    499 MB  Healthy    System

Close diskpart:

DISKPART> exit

Navigate to C:\ (or what your system drive letter is):

X:\Sources> cd /d C:\

Next is the «magic» command, which recreate the BCD store (with /s for the mount point, /f for firmware type, optionally add /v for verbose):

C:\> bcdboot C:\Windows /s G: /f UEFI

Tip: If it hangs up after a minute, hit Ctrl+c. This happens sometimes, but you will get a message like boot files successfully created and it will have worked just fine.

You should now have Windows Boot Manager working as a boot option, and thus have access to Windows. Just make sure to never format your EFI system partition again!

Note: Remove the drive letter G assigned to the EFI system partition to keep it from showing up in My Computer.

See [6], [7] and [8].

The EFI system partition created by Windows Setup is too small

By default, Windows Setup creates a 100 MiB EFI system partition (except for Advanced Format 4K native drives where it creates a 300 MiB ESP). This is generally too small to fit everything you need. You can replace the existing EFI system partition with a new, larger one.

If you are installing Windows from scratch, you can dictate the size of the EFI system partition during installation[9]:

1. Select your installation target and make sure it has no partitions.
2. Click New and then the Apply buttons. The Windows installer will then generate the expected partitions (allocating nearly everything to its primary partition) and just 100MB to the EFI.
3. Use the UI to delete the System, MSR, and Primary partitions. Leave the Recovery partition (if present) alone.
4. Press Shift+F10 to open the Command Prompt.
5. Type diskpart.exe and press Enter to open the disk partitioning tool.
6. Type list disk and press Enter to list your disks. Find the one you intend to modify and note its disk number.
7. Type select disk disk_number with the disk number to modify.
8. Type create partition efi size=size with the desired size of the ESP in Mebibytes (MiB), and press Enter. See the note at EFI system partition#Create the partition for the recommended sizes.
9. Type format quick fs=fat32 label=System and press Enter to format the ESP
10. Type exit and press Enter to exit the disk partitioning tool and exit followed by Enter again.

Once Windows is installed, you can resize the primary partition down within Windows and then reboot and go about your usual Arch install, filling the space you just created.

Alternatively, you can use the Arch install media to create a single EFI system partition of your preferred size before you install Windows on the drive. Windows Setup will use the EFI system partition you made instead of creating its own.

Unable to install Windows Cumulative Update on BIOS system

On BIOS systems, Windows cumulative updates may fail with the error We couldn’t complete the updates. Undoing changes. Don’t turn off your computer. In such case, while in Windows, you need to set the Windows partition as active.

C:\> diskpart
DISKPART> list disk
DISKPART> select disk number
DISKPART> list partition
DISKPART> select partition number
DISKPART> active
DISKPART> exit

After successfully installing the Windows update, mark back your Linux partition as active, using the commands above.

Note: Setting a partition as active in the diskpart tool in Windows has the same effect as setting the boot flag in GParted.

Time standard

• Recommended: Set both Arch Linux and Windows to use UTC, following System time#UTC in Microsoft Windows. Some versions of Windows revert the hardware clock back to localtime if they are set to synchronize the time online. This issue appears to be fixed in Windows 10.
• Not recommended: Set Arch Linux to localtime and disable all time synchronization daemons. This will let Windows take care of hardware clock corrections and you will need to remember to boot into Windows at least two times a year (in Spring and Autumn) when DST kicks in. So please do not ask on the forums why the clock is one hour behind or ahead if you usually go for days or weeks without booting into Windows.

Bluetooth pairing

When it comes to pairing Bluetooth devices with both the Linux and Windows installation, both systems have the same MAC address, but will use different link keys generated during the pairing process. This results in the device being unable to connect to one installation, after it has been paired with the other. To allow a device to connect to either installation without re-pairing, follow Bluetooth#Dual boot pairing.

Download ArchLinux & Make Bootable USB

• Download the Arch ISO from HERE
• Connect a USB stick to your computer.Use Rufus to burn the downloaded ISO image to the USB drive.

Create System Restore Point

It is recommended to create a System Restore point before installing Archlinux. This option allows you to take a snapshot of the current state of the system. If something goes wrong with the Arch installation, you can use this backup to restore your system to normal. 

BIOS Settings

• Reboot your computer.
• During the reboot, enter the BIOS settings using the keyboard shortcut (commonly F2, F9, or ESC).
• In UEFI BIOS, enable USB boot and set the USB drive as the primary boot order.
• Disable secure boot in the BIOS settings.
• If available, enable options like Microsoft’s third-party UEFI.
• Consider clearing any keys or certificates after disabling secure boot.
• Save the changes in the BIOS settings.
• Your system should now boot into ArchLinux from the USB drive.
• If the boot fails, use the boot menu to load Arch install media.

Increase Console FONT

Now, on your monitor, you will see a terminal expecting input.  Note that the mouse functionality is disabled so you need to rely on the keyboard

Type setfont ter-132n and press enter to increase the size of the console.

Using iWCTL for WIFI Connection

If using built-in WiFi support,  use the iwctl tool to connect to the internet.

• To find list of network interfaces type: iwctl device list
• To search for WIFI Networks type: iwctl station wlan0 get-networks
• To connect to WIFI network type: iwctl station wlan0 connect WIFI_NAME
• Once connected run : ping google.com to check internet connection (Interrupt Ping with CTRL + C)
• Then type the command to syncnorize the package database: pacman -Sy
• Then Type this command : pacman -S archlinux-keyring

Create Partitions For Arch Linux 

• Type lsblk to list all connected drives on the PC.
• Identify the main drives, focusing on SDA or NVME (ignore loops).
• NVME0n1 is MY drive with Windows 11, and SDA is the BootableUSB.

• Create partitions for Arch Linux using earlier free space.
• Type cfdisk /dev/nvme0n1 and press enter.
• Use arrow keys for selection and enter key for confirmation.

Картинка с сайта: kskroyal.com

• Scroll to free space and create 3 partitions: EFI, ROOT, and swap.
• Create EFI partition (e.g., 800MB) with type EFI System.
• Create ROOT partition (e.g., 20GB or higher) with type Linux file system.
• Use remaining free space for swap partition with type Linux SWAP.
• Write changes to alter the disk and exit from CFDisk.

Formatting Partitions 

• Type lsblk to view all newly created partitions
• NVME0N1P5 for EFI, NVME0N1P6 for Root, and NVME0N1P7 for Swap.
• Format the Arch EFI Partition (e.g., NVME0N1p5)
  mkfs.fat -F32 /dev/nvme0n1p5
• Format the root partition (e.g., NVME0N1p6)
  mkfs.ext4 /dev/NVME0N1p6
• Format the swap partition (e.g., nvme0n1p7)
  mkswap /dev/nvme0n1p7

Mount Partitions

• Mount the root partition (e.g., NVME0n1p6) to the “mnt” directory.
  mount /dev/nvme0n1p6 /mnt
• Create a directory inside “mnt” and name it “boot,” then mount the EFI partition to this directory.

mkdir /mnt/boot

mount /dev/nvme0n1p5 /mnt/boot

• Enable the swap partition by typing
  swapon /dev/nvme0n1p7
• Verify proper mounting of all partitions by typing lsblk

Installing ArchLinux

Now, it’s time to install the Arch Linux to the root partition which Is mounted to /mnt. 

pacstrap -i /mnt base base-devel linux linux-headers linux-firmware amd-ucode sudo git nano vim neofetch htop cmake make bluez bluez-utils networkmanager cargo gcc mpv

Run the above command to start installing the base system of Arch Linux. Accept the defaults.  This will take some time, sit back, relax, and don’t interrupt the computer.

Generate File System Table (FSTAB)

It’s time to generate a file system table. If you notice, the NVME partitions are mounted to the live session of USB, but when we boot arch from the main drive we need to tell the system to mount all these partitions to the same location.

genfstab -U /mnt >> /mnt/etc/fstab

CHROOT To Newley Installed system

So far we are running everything from the Live Session. It’s Time to enter, into the drive where we have installed Arch Linux. For that type:

 arch-chroot /mnt

Картинка с сайта: kskroyal.com

Now you can see the prompt has changed to something else, which means we have entered into the actual drive as a root user. 

Change Root Password

Then type passwd and set the root password. This is a superuser account and is known as a top-tier user in Linux. 

Adding a Standard User

Also, we are going to create a standard user by tying the below command and replace the username placeholder with your name

useradd -m -g users -G wheel,storage,video,audio -s /bin/bash USER_NAME

Then set the password by typing 

passwd USER_NAME

Now, we have added this new user to the wheel group and other groups. The Wheel group allows the user to access root privileges with a sudo command. For that, we need to edit the sudoers file. Type the below command

EDITOR=nano visudo

Make sure you replace the GREEN part with your hostname and save the changes

Grub-Installation

It’s time to install the grub boot loader which is going to help boot arch Linux.  Type the below commands

pacman -S grub efibootmgr dosfstools mtools

grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=GRUB

grub-mkconfig -o /boot/grub/grub.cfg

Enable Services

systemctl enable bluetooth

systemctl enable NetworkManager

Then exit from Chroot by typing exit & Unmount the partitions by typing

umount -lR /mnt

Shutdown the computer and eject the USB Stick

Connecting TO WIFI Using NMCLI

Once the system is restarted you can see the grub menu. From here you can boot into only Arch for now and Windows 11 boot entry will be missing.

We are going to fix that issue in a moment. For now, let’s just boot into Arch Linux. Now log in with your user account & increase the console font by typing below command

setfont -d

• Check the status of all network interfaces: nmcli dev status
• Turn on the WIFI Radio: nmcli radio wifi on.
• View available wifi networks with the command specified
  nmcli dev wifi list
• Connect to wifi using the relevant command, replace placeholders with your network information and enclosing the password in double-quotes
  sudo nmcli dev wifi connect WIFI_NAME password "WIFI_PASSWORD"
• Update the PACMAN database with: sudo pacman -Sy

Installing GUI

It’s time to install the desktop environment. For Plasma Desktop Run the below commands

sudo pacman -S xorg sddm plasma-meta plasma-wayland-session kde-applications noto-fonts noto-font-emoji ttf-dejavu ttf-font-awesome

sudo systemctl enable sddm

For GNOME Desktop

sudo pacman -S xorg gdm gnome gnome-extra 

sudo systemctl enable gdm

Then Reboot the system

sudo reboot now

and this time Arch Linux will boot With a GUI Environment

Fix Discover App Backend

The first thing to do after installing ArchLinux is to fix the Discover app backend. To do so open KONSOLE and type the below command to install flatpak and use it as a backend for discover. 

sudo pacman -Sy flatpak

Install NVIDIA Drivers (Optional)

If you have a modern NVIDIA graphic card, it’s recommended to install NVIDIA proprietary drivers.

"This is completely optional, installing this package on older systems may or may not work, so please refer to this article"

Anyway, inside the konsole you can type the below command to set up NVIDIA drivers.

sudo pacman -Sy nvidia

  Once it’s done, reboot your computer. Now if I type nvidia-smi command inside the terminal you can see it shows the NVIDIA driver information.

Reboot the system. Using the grub menu you can boot into either Arch or Windows 11

Removing ArchLinux From Dual Boot

• Reboot your computer and boot into Windows 11.
• Open Disk Management utility by typing diskmgmt in the search bar.
• Delete each new partition by right Clicking created during ArchLinux installation, starting with swap and root partitions.

Картинка с сайта: kskroyal.com

• “Note that the LINUX EFI partition cannot be deleted using Disk Management“
• Open Command Prompt as an administrator and type DISKPART
• Type list disk to view all connected drives, select the appropriate drive with
  select disk 0
• Type list partition to view all partitions on the selected drive.
• Identify the Arch EFI partition (e.g., partition 5).

Картинка с сайта: kskroyal.com

• Select the Arch EFI partition with select partition [number]
• Type DELETE PARTITION OVERRIDE to remove the partition.
• Verify the deletion in Disk Management; the free space is now available.
• Utilize the gained free space to merge it back into Windows 11 partitions

Watch the YouTube Video:

1. Pre-Installation Preparation

Before touching partitions, back up any important files from your Windows system. Verify that Windows is installed in UEFI mode: in Windows press Win+R, run msinfo32, and ensure BIOS Mode is “UEFI” (Installing And Setting Up Arch Linux to Dual Boot Alongside Window 10 · GitHub). Also confirm Windows uses GPT, not MBR, in Disk Management. Next, disable “Fast Startup” in Windows (via Control Panel → Power Options) because it hibernates the disk and can block Linux from mounting it (Is it necessary to disable Fast Boot in Windows to dual boot with linux(EFISTUB)? — Unix & Linux Stack Exchange). In your PC’s UEFI/BIOS settings, disable Secure Boot if possible (this avoids bootloader signature issues) and Fast Boot (if present, to ensure the USB can boot).

Download the Arch Linux ISO from the official site and create a bootable USB. For example, use a tool like Rufus on Windows: select the ISO, set the partition scheme to GPT and file system to FAT32, and flash it (Installing And Setting Up Arch Linux to Dual Boot Alongside Window 10 · GitHub). This makes the USB UEFI-bootable. When done, reboot and enter your firmware’s boot menu (often by pressing a key like F12, F10, or Esc during startup) and choose the USB under UEFI devices (Installing And Setting Up Arch Linux to Dual Boot Alongside Window 10 · GitHub).

2. Booting Arch Linux in UEFI Mode

Boot the USB in UEFI mode. You should land at an Arch Linux prompt (typically as the root user, no password). If needed, set your keyboard layout (e.g. loadkeys us for US layout) and verify network connectivity next.

3. Internet Connection (Wi-Fi)

If you have a wired connection, it usually connects automatically via DHCP. Test it with ping -c 3 archlinux.org. For Wi-Fi, run:

rfkill unblock wifi 
iw dev        # identify your wireless interface name (e.g. wlan0)
wifi-menu wlan0   # (or your interface name) to select and connect to a network

After connecting, verify with ping -c 3 archlinux.org. A working connection is required for package installation (Installing And Setting Up Arch Linux to Dual Boot Alongside Window 10 · GitHub).

4. Disk Partitioning

WARNING: Be careful not to delete your Windows partitions. You may have already shrunk the Windows partition from Windows Disk Management to make free space. If not, reboot into Windows, open Disk Management (diskmgmt.msc), right-click the Windows (C:) partition, and choose Shrink Volume to free up at least ~20–50 GB (20000–50000 MB) for Arch (Installing And Setting Up Arch Linux to Dual Boot Alongside Window 10 · GitHub).

Back in Arch’s live environment, list disks with fdisk -l to identify your drive (e.g. /dev/sda). Use cfdisk (or fdisk/gdisk) to partition. Select your disk (e.g. /dev/sda) and a GPT label:

cfdisk /dev/sda

In the cfdisk menu, create new partitions in the free space:

• EFI System Partition (ESP): If Windows is already in UEFI mode, an EFI partition (around 100–500 MB, FAT32) should exist (often /dev/sda1). We will reuse that for the bootloader. If not present, create a new small (e.g. 500 MB) FAT32 partition and set its type to “EFI System” (How to Install Arch Linux: A Beginner’s Practical Guide).
• Swap Partition: Create a Linux swap partition. For example, if you have 8 GB RAM, make 8–12 GB here. After selecting “New”, accept the defaults to start at free space and enter the size (e.g. 12G), then set its type to “Linux swap” (How to Install Arch Linux: A Beginner’s Practical Guide).
• Root Partition: Use the remaining space to create an ext4 root partition. Again select “New”, accept the remaining free space, and set the type to “Linux filesystem” (ID 8300) (How to Install Arch Linux: A Beginner’s Practical Guide).

Write the changes (“Write” in cfdisk) and confirm. Then quit cfdisk (How to Install Arch Linux: A Beginner’s Practical Guide).

5. Format and Mount Partitions

Format each partition to its filesystem:

mkfs.fat -F32 /dev/sda1     # Format EFI partition as FAT32 (if newly created; skip if reusing Windows EFI)
mkswap /dev/sda2            # Format swap partition
swapon /dev/sda2            # Enable swap
mkfs.ext4 /dev/sda3         # Format root partition as ext4

(Adjust /dev/sdXN numbers to match your EFI, swap, and root partitions.) Format and activate swap as shown (How to Install Arch Linux: A Beginner’s Practical Guide); format root as ext4 (How to Install Arch Linux: A Beginner’s Practical Guide).

Next, mount the new root partition and EFI partition (bootloader space). For example:

mount /dev/sda3 /mnt       # Mount the root partition
mkdir -p /mnt/boot/efi     # Create a mount point for EFI
mount /dev/sda1 /mnt/boot/efi  # Mount the EFI (ESP) here

(This assumes /dev/sda1 is the EFI; use the correct device.) These commands are analogous to those shown in the guide (How to Install Arch Linux: A Beginner’s Practical Guide). Verify with lsblk that /mnt is your root and /mnt/boot/efi is your EFI.

6. Install the Base System

Install the core Arch system packages using pacstrap:

pacstrap /mnt base linux linux-firmware

This installs the base filesystem, the Linux kernel, and firmware for common devices (Comprehensive Arch Linux Installation Guide | Liquid Web). You can also add packages like base-devel or a text editor here (e.g. nano) as needed.

7. Configure the New System

Generate an fstab file so the system knows where to mount partitions on boot:

genfstab -U /mnt >> /mnt/etc/fstab

Review it with cat /mnt/etc/fstab to ensure it lists your root and EFI partitions correctly (Comprehensive Arch Linux Installation Guide | Liquid Web).

Now enter the new system environment with arch-chroot:

arch-chroot /mnt

You are now effectively “root” in your installed system. All following commands apply inside the new Arch system.

Timezone and Clock

Set your timezone, for example for New York:

ln -sf /usr/share/zoneinfo/America/New_York /etc/localtime
hwclock --systohc

This links the appropriate zoneinfo file and generates /etc/adjtime (Comprehensive Arch Linux Installation Guide | Liquid Web) (Comprehensive Arch Linux Installation Guide | Liquid Web). Replace the path with your region/city.

Locale

Edit /etc/locale.gen, uncomment your locale (e.g. en_US.UTF-8 UTF-8), then run:

locale-gen
echo LANG=en_US.UTF-8 > /etc/locale.conf

These commands (and uncommenting the locale) are shown in the guide (Comprehensive Arch Linux Installation Guide | Liquid Web) (Comprehensive Arch Linux Installation Guide | Liquid Web). This sets the system language.

Hostname and Hosts

Set a hostname by creating /etc/hostname with your chosen name. For example:

echo "archpc" > /etc/hostname

Then edit /etc/hosts and add lines:

127.0.0.1   localhost
::1         localhost
127.0.1.1   archpc.localdomain   archpc

Replace archpc with your hostname as shown (Comprehensive Arch Linux Installation Guide | Liquid Web).

Root Password and Initramfs

Set the root password:

passwd

Enter a secure password when prompted (Comprehensive Arch Linux Installation Guide | Liquid Web). Then rebuild the initial ramdisk:

mkinitcpio -P

This ensures the boot image is up-to-date (most tutorials include this step).

Create a Regular User (optional but recommended)

Create a normal user for daily use and add it to the “wheel” group (for sudo). For example:

useradd -m -G wheel -s /bin/bash username
passwd username

Give that user a password. Then install and enable sudo by editing /etc/sudoers with EDITOR=nano visudo and uncommenting the line %wheel ALL=(ALL) ALL.

8. Install the Bootloader (GRUB)

Install GRUB with UEFI support so you can boot Arch (and Windows). First, install the packages:

pacman -S grub efibootmgr os-prober

Here, os-prober helps detect Windows. Now install GRUB to the EFI directory and generate its config:

grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=GRUB
grub-mkconfig -o /boot/grub/grub.cfg

These commands create the GRUB UEFI entry (How to Install & Configure Arch Linux on UEFI Systems) (How to Install & Configure Arch Linux on UEFI Systems). If everything works, /boot/grub/grub.cfg will be generated and should include menu entries for both Arch and Windows. (If Windows is not listed, ensure os-prober was installed and re-run grub-mkconfig.)

9. Install KDE Plasma and SDDM

If you want a graphical desktop, install KDE Plasma and its apps. For a full set:

pacman -S plasma-meta kde-applications-meta

This pulls in the KDE desktop environment and standard KDE apps (How to Install Arch Linux: A Beginner’s Practical Guide). You may also install a graphical display server (xorg) if not already installed.

Enable the SDDM display/login manager (default for KDE) and networking (using NetworkManager, since you used NetworkManager earlier):

systemctl enable sddm
systemctl enable NetworkManager

This ensures KDE’s login screen and network service start at boot (How to Install Arch Linux: A Beginner’s Practical Guide). (You could also use dhcpcd or another network service if you prefer.)

10. Finalize and Reboot

Exit the chroot, unmount partitions, and reboot:

exit
umount -R /mnt
reboot

Remove the USB drive when the system shuts down. On reboot, you should see the GRUB menu offering Arch Linux and Windows. Select Arch to boot into your new system with KDE. Log in as your new user or root (depending on setup) and enjoy Arch Linux! (How to Install Arch Linux: A Beginner’s Practical Guide).

Common Pitfalls: Be careful not to overwrite the Windows partitions. Always confirm device names (/dev/sdX) before formatting. If GRUB doesn’t show Windows, ensure os-prober is installed and rerun grub-mkconfig. Disabling Fast Startup in Windows is essential; otherwise Linux will refuse to mount the Windows drive (Is it necessary to disable Fast Boot in Windows to dual boot with linux(EFISTUB)? — Unix & Linux Stack Exchange). Ensure your firmware is booting in UEFI mode (not legacy) for both OSes, or the dual-boot will fail.
