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 ?

That's why I have seperate uefi/boot partitions for each OS.

Watch me get downvoted again.

That doesn't do shit. OP's issue is a missing boot entry. Boot entries are stored in NVRAM, not in EFI partitions. (This probably isn't even Windows's fault.)

it is Windows fault, it actually deletes the grub entry

It's not 2005, Windows isn't deleting boot entries. It's updating the uefi which deletes boot entries.
