Rocky not showing in BIOS Boot entries

Rocky Linux Help & Support
,
1

I am on a multiple OS system with 3 drives, one for rocky 8.10, one for windows, and another for NobaraOS. I recently updated my BIOS to F20d (I have the B550M DS3H), but now the boot entries only show Nobara and Windows, rocky is missing. I attempted to, in windows, run bcedit /set {bootmgr} path \EFI\rocky\grubx64.efi but that just added another Windows entry to the boot options.

Some potentially useful info

First a note: the ‘lsblk’ does not require ‘sudo’. Nice. Second, with lsblk -f you do see filesystem types and UUIDs too.

You can run efibootmgr in Nobara. That can create/delete boot entries.

You have ESP on two drives? One you have mounted as /boot/efi on Nobara.
If it has the directory for Rocky too, then create entry like the “Fedora” (with correct path to shim).

If not, then mount the other ESP somewhere to check that Rocky’s files are there and
create entry with that partition UUID (that sudo blkid should tell / is on the Windows entries).

So when it was working, how did you choose the o/s to run? Were you using the BIOS menu selector (as opposed to grub)?

The Rocky entry is no longer on the BIOS menu, but what about the boot order list in the BIOS, is it missing from there too?
