Grub2 windows boot manager — Ваш верный помощник с OS Windows

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?

Also, since Head_on_a_stick asked, there you go

Why Do You Need to Replace GRUB With Windows Boot Manager

GRUB is often set as the bootloader when you dual-boot a Linux distro with Windows. This can ensure that there’re no conflicts between the two operating systems in the load-up process. Though GRUB is a versatile and easy-to-use bootloader, you may still want to set Windows Boot Manager as the default because of errors like GRUB not showing in dual boot setup or something else.

Here comes the question: how to switch from GRUB to Windows Boot Manager. Well, you don’t have to worry about it. This post would illustrate the whole process for you.

Further reading:

Windows Boot Manager (BOOTMGR) is a small piece of software that is loaded from the volume boot code. It enables you to boot operating systems including Windows Vista/7/8/10. However, it can prompt you with various errors.

For instance, you will receive errors like BOOTMGR is missing, Boot Manager failed to find OS loader, BOOTMGR is compressed, etc. If you are bothered by issues like that, try using MiniTool Partition Wizard to fix them.

Step 1: Open Settings by pressing Windows and I keys.

Step 2: Then click Update & Security > Recovery > Restart now (under the Advanced startup section).

Step 3: Click on Troubleshoot > Advanced options > UEFI Firmware Settings and tap Restart.

Step 4: After the computer restarts, it will enter the UEFI/BIOS setup utility.

Fortunately, it’s relatively easy to add a Windows boot entry to GRUB. In this guide, I’ll show you how to do just that. I’ll also provide some tips on troubleshooting common problems.

So, if you’re ready to learn how to add a Windows boot entry to GRUB, read on!

Troubleshooting GRUB boot problems	This guide will help you troubleshoot GRUB boot problems, such as when GRUB is not showing up, or when you are unable to boot into Windows from GRUB.	Troubleshooting GRUB Boot Problems

What is GRUB and why do you need it?

GRUB, which stands for GRand Unified Bootloader, is a bootloader that is used to load the operating system (OS) on a computer. It is a very versatile bootloader that can be used to boot multiple operating systems from the same computer, as well as to boot from a USB drive or CD-ROM.

GRUB is installed on the master boot record (MBR) of the hard drive, and it is the first thing that is loaded when the computer starts up. GRUB then scans the hard drive for operating systems and presents a menu from which the user can select which OS to boot.

GRUB is a very important part of the boot process, and it is essential for ensuring that the correct operating system is loaded. If GRUB is not working properly, it can prevent the computer from booting up correctly.

Adding a Windows boot entry to GRUB is a relatively simple process, but there are a few things that you need to know in order to do it correctly.

First, you need to know the location of the Windows installation files. This is usually located in the `/boot/efi` directory on the hard drive.

Second, you need to know the name of the Windows boot loader. This is usually called `bootmgfw.efi`.

Once you have this information, you can follow these steps to add a Windows boot entry to GRUB:

1. Open the GRUB configuration file. This file is located in the `/etc/grub.d/` directory.
2. Find the section that starts with `menuentry “Windows”`.
3. Add the following lines to the end of the section:

set root=(hd0,gpt2)
chainloader /EFI/Microsoft/Boot/bootmgfw.efi

4. Save the GRUB configuration file.
5. Regenerate the GRUB bootloader. This can be done by running the following command:

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

6. Reboot the computer.

Once the computer has rebooted, you should see the Windows boot entry in the GRUB menu. You can select this entry to boot into Windows.

GRUB is a powerful and versatile bootloader that can be used to boot multiple operating systems from the same computer. Adding a Windows boot entry to GRUB is a relatively simple process, and it can be done by following the steps in this guide.

Troubleshooting common problems

Here are some common problems that you may encounter when trying to add a Windows boot entry to GRUB:

The Windows boot entry is not showing up in the GRUB menu. This is usually caused by a missing or incorrect configuration file. To fix this, you can try reinstalling GRUB or manually editing the GRUB configuration file.
The Windows boot entry is not working. This can be caused by a number of factors, such as a corrupt Windows installation or a missing or incorrect driver. To fix this, you can try reinstalling Windows, updating your drivers, or using a third-party bootloader.
The Windows boot entry is taking too long to load. This can be caused by a number of factors, such as a slow hard drive or a large Windows installation. To fix this, you can try defragmenting your hard drive or reducing the size of your Windows installation.

If you are having trouble troubleshooting these problems, you can try asking for help on a Linux forum or mailing list.

Tips and tricks for using GRUB

Here are some tips and tricks for using GRUB:

To add a new boot entry, you can use the `grub-install` command. This command will install GRUB to the specified device and create a new boot entry for the specified operating system.
To edit a boot entry, you can use the `grub-editenv` command. This command will open the GRUB configuration file in a text editor, where you can make changes to the boot entry.
To delete a boot entry, you can use the `grub-remove-menuentry` command. This command will delete the specified boot entry from the GRUB menu.
To change the order of the boot entries, you can use the `grub-set-default` command. This command will set the specified boot entry as the default boot entry.
To change the timeout for the GRUB menu, you can use the `grub-set-timeout` command. This command will set the number of seconds that the GRUB menu will be displayed before automatically booting the default boot entry.

For more information on using GRUB, you can refer to the GRUB documentation.
