So basically, I had ubuntu 18,04 installed with windows (dual boot) for about 4 months. When i booted the PC it automatically loaded GRUB in the past. Now when i boot the pc up it automatically always go to the bios no matter what. I tried to switch the boot priority order so it would boot to a boot-repair USB key(that i flashed), it didnt, i tried to boot from the windows boot manager, it didnt. No matter what device i put in what order in the boot priority order, it always go to the bios regardless.
Boot mode is set in UEFI, i set the shimx64.efi to trusted, i disabled secure boot.
Any help would be greatly appreciated
