The partition table type is completely irrelevant. The problem is that
the firmware does not understand mdadm RAID. You can either place the
EFI boot partition on a non-RAID partition, put it on a USB stick and
boot from that, or manually duplicate a non-RAID EFI boot partition to
the other disk and add UEFI boot entries for it with 'efibootmgr'.
