[SOLVED] Grub isn't listed in bios boot order UEFI

After installing arch dual boot with windows and installing grub with "grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=GRUB" and "grub-mkconfig -o /boot/grub/grub.cfg" the grub boot option appeared in the boot menu after and i can
boot grub through there but grub didn't appear in the bios boot order.

here is the output of "efibootmgr -v"

Re: [SOLVED] Grub isn't listed in bios boot order UEFI

What BIOS/mainboard? Some vendors require some more specific setup

Msi tomohawk MAX b450  i believe. i managed to get it working by using bcdedit in windows by createing a boot entry. Thanks for responding.   would there be a easier way to do it then that?

Re: [SOLVED] Grub isn't listed in bios boot order UEFI

MSI are notorious for a broken UEFI implementation, adjusting and adding a entry in the Windows boot loader is probably the most sustainable way, another would be replacing the binary in the fallback path: https://wiki.archlinux.org/title/Unifie … ble_drives which can be done by either copying the GRUB binary manually or running the install command with the --removable argument, however the fallback path will be overwritten by Windows updates concerning the boot loader.

If this is [SOLVED] please mark it as such by prepending to your title.
