How to uninstall GRUB

GRUB (GRand Unified Bootloader) is a bootloader that is used to boot Linux and other operating systems. If you want to uninstall GRUB from your system, you will need to follow a few steps depending on your specific setup.

Here is a general outline of the process:

1. Boot your system from a live Linux installation media (such as a DVD or USB stick) or a Windows installation media.

2. Once the live system has booted, open a terminal and use the fdisk or gdisk command to view your disk partitions. Make a note of the partition that contains your Windows installation.

3. Use the bootrec utility to repair the Windows bootloader. On a Windows installation media, you can run the following commands:

bootrec /fixmbr
bootrec /fixboot

4. If your system has a UEFI bootloader, you may also need to use the bcdboot utility to repair the bootloader. You can do this by running the following command:

bcdboot C:\Windows /l en-us /s <drive letter>:

Where C:\Windows is the path to your Windows installation and <drive letter>: is the drive letter of the partition that contains your Windows installation.

5. Reboot your system and check if the Windows bootloader has been restored. If everything is working correctly, you should be able to boot into Windows without GRUB.

Keep in mind that uninstalling GRUB may prevent you from booting into Linux or other operating systems that rely on GRUB as the bootloader. If you want to switch to a different bootloader or change the way your system boots, you may want to consider other options instead of uninstalling GRUB.

If you are not comfortable with using the command line or working with disk partitions, you may want to seek the help of a qualified professional or refer to detailed documentation and instructions.
