How to remove grub bootloader?

[OmegaDaBoi]

I tried to replace Linux Mint Una with Windows 10 21h2 after trying it, but then when I reboot it shows

 

error: unknown filesystem

Entering rescue mode..

grub rescue>

 

How to remove GRUB to fix this?

I had the same issue. create a custom boot option pointing to windows. I'll give you exact path if you want

 

Edit: look up how to create a custom boot entry on your specific bios and here's the path assuming windows is installed correctly

"\EFI\Microsoft\Boot\en-US(might be different for you)\bootmgfw.efi.mui"

 

Another edit: there is nothing in the boot sector/that file doesn't exist it will have to be rebuilt http://woshub.com/how-to-repair-deleted-efi-partition-in-windows-7/

 

lemme know how it goes

There are no guides for a custom boot entry in my BIOS (Aorus elite b450)

 

Edit: I am trying to dualboot Linux with Windows to make this work.

 

Edit 2: My janky solution worked and now I can boot into windows from Grub.
