I do not know much about UEFI booting -- just enough to dislike it. I
find it complicated to get working correctly, and fragile when it
does.

Possibilities:
* if the disk is partitioned with GPT, do you have a BIOS_GRUB partition?
* if you have more than 1 disk, does only 1 have an ESP?
* is your ESP being mounted under /boot/efi so that Linux can find it
when updating the bootloader?
