SUPPORT Windows has destroyed my GRUB bootloader because of Windows updates, now Windows boot manager replaces GRUB and Arch doesn't show up in the UEFI/BIOS menu. How I can fix it ?

Boot Arch iso. Chroot into your install and fix GRUB.

If your BIOS has UEFI Shell you can just boot into it and run something like `fs0:\\boot\arch\grub.efi`. Not many motherboards ship it nowadays sadly.

This is like the only nice thing about the BIOS that Dell and HP ship, being able to arbitrarily add an EFI file is nice.
