How to add windows to grub — Ваш верный помощник с OS Windows

Adding Windows to GRUB

If you’re dual-booting Windows and Linux, you’ll need to use GRUB to select which operating system to boot into. By default, GRUB will only list the Linux kernel, but you can easily add Windows to GRUB so that you can choose between the two operating systems at boot time.

Adding Windows to GRUB is a relatively simple process, but there are a few things you need to know before you get started. In this article, I’ll walk you through the steps of adding Windows to GRUB, so you can have both operating systems on your computer and easily choose between them at boot time.

What is GRUB?

GRUB is a boot loader that is used to load the operating system kernel. When you turn on your computer, the BIOS will look for a boot loader to load the operating system. If GRUB is installed, it will be loaded and will display a menu of operating systems that you can choose to boot into.

How to add Windows to GRUB

To add Windows to GRUB, you’ll need to:

1. Find the Windows installation media.
2. Boot from the Windows installation media.
3. Select Install now.
4. At the Where do you want to install Windows? screen, select Custom.
5. Select the Drive 0 Partition 1 (or whichever partition you installed Windows to) and click Format.
6. Click Next.
7. Click Install.
8. When the installation is complete, reboot your computer.

Once your computer has rebooted, you should see the GRUB menu. Use the arrow keys to select Windows and press Enter to boot into Windows.

Adding Windows to GRUB is a relatively simple process, but it’s important to follow the steps carefully to avoid any problems. By following the steps in this article, you can have both Windows and Linux on your computer and easily choose between them at boot time.

Step	Instructions	Notes
1	Boot into the live environment of your Linux distribution.
2	Open a terminal window.
3	Install the grub-efi package.	This package provides the GRUB bootloader for EFI systems.
4	Create a new entry for Windows in the GRUB configuration file.	The following is an example of a GRUB configuration entry for Windows: menuentry “Windows 10” { linuxefi /EFI/Microsoft/Boot/bootmgfw.efi initrdefi /EFI/Microsoft/Boot/wimboot.efi } You can find more information about creating GRUB configuration entries in the GRUB documentation.
5	Reboot your system.	When your system boots, you should see the GRUB menu. Use the arrow keys to select the Windows entry and press Enter to boot into Windows.

GRUB is a boot loader that can be used to select the operating system that will be booted when a computer is turned on. GRUB can be used to boot multiple operating systems from a single hard drive, or to boot from a USB drive or CD-ROM. GRUB is configured using a text file called `/etc/grub.conf`.

What is GRUB?

GRUB is a free and open-source boot loader that can be used to select the operating system that will be booted when a computer is turned on. GRUB can be used to boot multiple operating systems from a single hard drive, or to boot from a USB drive or CD-ROM. GRUB is configured using a text file called `/etc/grub.conf`.

GRUB was originally developed by Erich Stefan Boleyn in 1995. It was originally called GRand Unified Bootloader, but the name was later shortened to GRUB. GRUB is now maintained by a team of developers under the auspices of the GNU Project.

GRUB is a very versatile boot loader. It can be used to boot a wide variety of operating systems, including Linux, Windows, macOS, and FreeBSD. GRUB can also be used to boot from a USB drive or CD-ROM.

GRUB is configured using a text file called `/etc/grub.conf`. This file contains a list of all the operating systems that GRUB can boot, as well as the options that are used to boot each operating system.

How to add Windows to GRUB

To add Windows to GRUB, you will need to know the location of the Windows boot loader. The Windows boot loader is located in the `\boot\bcd` directory.

To add Windows to GRUB, you will need to edit the `/etc/grub.conf` file. You can do this using any text editor.

To add Windows to GRUB, you will need to add a new entry to the `/etc/grub.conf` file. The new entry should look something like this:

menuentry “Windows 10” {
chainloader /EFI/Microsoft/Boot/bootmgfw.efi
}

Once you have added the new entry to the `/etc/grub.conf` file, you will need to save the file and then reboot your computer.

When your computer reboots, you will be presented with a GRUB menu. You can use the arrow keys to select the Windows entry and then press Enter to boot into Windows.

GRUB is a powerful and versatile boot loader that can be used to boot multiple operating systems from a single hard drive. Adding Windows to GRUB is a relatively simple process, and it can be done by following the steps outlined in this article.

Adding Windows to GRUB

GRUB is a boot loader that can be used to select the operating system that will be booted when a computer is turned on. By default, GRUB only lists Linux operating systems, but it can be configured to also list Windows operating systems.

To add Windows to GRUB, you will need to:

1. Install the GRUB boot loader on your Windows system.
2. Create a GRUB configuration file that lists the Windows operating system.
3. Update the GRUB configuration file.

Installing the GRUB boot loader on Windows

The GRUB boot loader can be installed on Windows using the GRUB2Win32 tool. To install GRUB2Win32, follow these steps:

1. Download the GRUB2Win32 tool from the GRUB2Win32 website.
2. Extract the downloaded file to a location on your Windows system.
3. Open the GRUB2Win32 tool.
4. Click the “Install” button.

The GRUB boot loader will be installed on your Windows system.

Creating a GRUB configuration file

The GRUB configuration file is a text file that lists the operating systems that GRUB will boot. To create a GRUB configuration file, follow these steps:

1. Open a text editor.
2. Type the following code into the text editor:

menuentry “Windows” {
insmod part_msdos
insmod ext2
set root=(hd0,gpt1)
search –no-floppy –fs-uuid –set=root 55AA55AA-55AA-55AA-55AA-55AA55AA55AA
chainloader /EFI/Microsoft/Boot/bootmgfw.efi
}

The code above lists the Windows operating system and specifies the location of the Windows boot loader.

Updating the GRUB configuration file

Once you have created the GRUB configuration file, you need to update the GRUB configuration file. To update the GRUB configuration file, follow these steps:

1. Open a terminal window.
2. Change to the directory where the GRUB configuration file is located.
3. Run the following command:

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

The GRUB configuration file will be updated.

Booting Windows from GRUB

Once you have added Windows to GRUB, you can boot Windows from GRUB by following these steps:

1. Turn on your computer.
2. Press the F12 key or the ESC key to open the boot menu.
3. Select the Windows entry from the boot menu.

Windows will be booted from GRUB.

Troubleshooting GRUB problems

If you are having problems with GRUB, there are a few things you can check:

Make sure that the Windows boot loader is located in the correct directory. The Windows boot loader is usually located in the `\EFI\Microsoft\Boot` directory.
Make sure that the `/etc/grub.conf` file is correct. The `/etc/grub.conf` file contains the configuration information for GRUB. You can use the `grub-editenv` command to view the `/etc/grub.conf` file.
Try reinstalling GRUB. You can reinstall GRUB using the `grub-install` command.

Tips for using GRUB

GRUB can be used to do more than just select the operating system that will be booted. You can also use GRUB to:

Change the boot order of your operating systems.
Boot into a recovery environment.
Create a bootable USB drive or CD-ROM.

To change the boot order of your operating systems, you can use the `set default` command. To boot into a recovery environment, you can use the `recovery` command. To create a bootable USB drive or CD-ROM, you can use the `grub-mkrescue` command.

GRUB is a powerful tool that can be used to manage the boot process on your computer. By adding Windows to GRUB, you can easily boot Windows from your Linux system.

I usually run Ubuntu and Windows on the same computer, in order to be able to select which OS I want to boot, I use GRUB. Here we’re going to learn how to add Windows 10 to the GRUB OS list.

Using your Ubuntu OS you need to know which partition is the Windows EFI located, mine is at /dev/sda2.

Once you know it, you should run the following command adapting it to your partition.

sudo blkid /dev/sda2

Enter fullscreen mode

Exit fullscreen mode

This command will allow you to know the UUID of your Windows EFI partition.

Next, we need to edit the /etc/grub.d/40_custom file in order to add the Windows 10 entry.

sudo vi /etc/grub.d/40_custom

Enter fullscreen mode

Exit fullscreen mode

Here is the entry you should add, change WINDOWS_EFI_PARTITION_UUID with the value you obtained previously.

menuentry "Windows 10" --class windows --class os {
   insmod ntfs
   search --no-floppy --set=root --fs-uuid WINDOWS_EFI_PARTITION_UUID
   ntldr /bootmgr
}

Enter fullscreen mode

Exit fullscreen mode

Sometimes the GRUB menu is hidden by default on boot, you should enable it changing the GRUB configuration.

sudo vi /etc/default/grub

Enter fullscreen mode

Exit fullscreen mode

You should set the timeout seconds, and comment out the default style.

GRUB_TIMEOUT=5
#GRUB_TIMEOUT_STYLE=hidden

Enter fullscreen mode

Exit fullscreen mode

Once you’ve made all the changes, you should apply them by running the following command.

sudo update-grub

Enter fullscreen mode

Exit fullscreen mode

No, i did not update /boot/grub/grub.cfg, and doing so indeed fixed the problem (

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

), Thanks everybody!
in grub, I now see

Arch Linux
Advanced options for Arch Linux
Windows Boot Manager (on /dev/nvme0n1p1)
UEFI Boot options
Windows
Windows

I managed to remove one of the «Windows» options by removing the added part in /etc/grub.d/40_custom, but the other one is still there
I dont necessarily need to remove it, I can live with it there, but it would be nice not to have it twice
also, if I try to boot into it, it says that there is no drive named /dev/nvme0n1p1, but that might also be due to a typo somewhere
I could select it from grub, press e to edit it and delete everything, but how would I save it, then?
