My experience with UEFI is that it is a black art. Fought with it until a deadline forced me to non-UEFI. In my case a drive-based UEFI partition (FAT32) was required. See if efibootmgr is available and would help you. I should note that, in the process. I discovered that the UEFI standard makes no provision for RAID if it is disk-based. I would love to hear someone contradict me on that and point me to documentation on how to do it without resorting to exotic maneuvers.

Subject: [EXTERNAL] [CentOS] UEFI booting
I installed my first UEFI disk yesterday. Seemed to go fine. CentOS 7.6
x86_64
I then took that disk "out" of that machine and put it another machine - it
seems to not even boot.
I put the original disk back in that machine and it boots fine.
I put the UEFI disk back in the machine I built it on and it works fine.
They are similar machines either and i3 and i7.
Shouldn't that work? Build a UEFI disk on machine A - move it to machine B?
Thanks
Jerry
