Hello, my Acer Nitro 5 AN515-54 has its BIOS inaccesable. When I attempt to go into the BIOS with the F2 key, it just shows an underscore and nothing else. Ive had this issue before already, the way I solved it was disabling secure boot, but secure boot is still disabled yet I still cant enter the BIOS. ive also tried entering from Windows, it still gives me that blinking light. I dont know what else to do.
Also, before this I kind of had a broken boot entry, there was only 1 boot entry showing in the BIOS, and it was a weird mess of characters, meanwhile when I went into the F12 menu, it showed all the boot entries fine. Anyone know why this is?

Thanks.

    This generally happens when the boot manager of bawked on the drive for some reason, or if grub is installed. if you remove the drive and boot are you able to access the uefi?

    Yes, I have installed Grub, yes removing the drive i am able to access the uefi. Why does the presence of grub lock the UEFI??? even with secure boot disabled? this is very puzzling.

    it doesnt lock it, theres a bug in the bootloader is my best guess🤷 it seems to happen quite a bit! Maybe it will be fixied in a future version of the UEFI or grub hopefully!

    My best guess is UEFI doesn`t like 2 efi partitions on one disk, I have grub  on one ssd and win boot manager on second ssd and no issues.

    Aye it could be something like that, where its enumerating boot flags, seeing two and having a bad day!

    No, I only have 1 EFI partitions on a disk.

    I dont see how this is an issue with GRUB, considering every single bootloader I have tried has this same issue. To me this just seems like a bad UEFI implementation

    I meant more on the Acer bootloader side opposed to grub,  my only guess is grubs doing something that the bootloader in the UEFI doesnt like, i agree with the bad uefi comment aha!

    I have this in /sys/efi/efivars/,
    You think deleting any of these might help?

    Don`t do that, delete grubx64.efi instead and rebuild grub after that.
