      In a properly implemented EFI, this should be possible. But there have been cases with improperly implemented EFI in some laptops/motherboards where the computer won’t POST after /sys/firmware/efi/efivars/ was nuked. In that case, accessing BIOS or booting from a flashdrive isn’t possible anymore.

        I have a little flash chip reader and backed up my bios and can flash it on the laptop. Even modified it to unlock the advanced menus Lol

        But th rm rf thing didn’t nuke it so I guess I’m safe either way

        Bro, BIOS is located on motherboard and EFI variables only needed to boot an OS.

        Just install bootloader and OS in drive

          Bro, several people bricked their pc that way. I’m no expert, just throwing out a warning not to do dumb shit.
