Grub bios issue (UEFI)

Hello, my grub install does not seem to work on my UEFI bios after a few reboots. If I point my bios to the grub .cfg or .efi files in my /dev/sdb1 partition (EFI install partition), an entry is created and i am allowed to reorder the boot order, but does not show up in the boot selector list. Reinstalling grub does not fix the issue, and rerunning the 'grub-mkconfig' command does not remake an EFI entry either.

Hardware Specifications:
Alienware Aurora R7 motherboard
Alienware Aurora R7 bios version 1.0.23
Arch Kernal 5.12

Re: Grub bios issue (UEFI)

grub-install should be the command that creates an entry. if that doesn't stick, make sure secureboot is disabled and maybe run the grub-install command with the --removable flag ammended so that the standard path of esp/EFI/BOOTX64.efi is populated. That one should get booted regardless of weird UEFI quirks.

Double checked secure boot was disabled in bios settings and tried to reinstall with the --removable flag. Grub-install ran fine with no errors and grub-mkconfig also ran fine. Bios settings (f2) sees a new boot entry but the boot device menu (f12) does not list the entry. Swapping the boot device priority in my bios settings also does not boot into grub.

Edit: Ran grub-mkconfig with /boot/EFI/BOOT/BOOTX64.EFI as its set path, no changes in my bios have been made.
