Okay.
Please check and post the Setup settings for the disk drive.
Please run and post:
# gdisk -l /dev/sda

Caution: invalid backup GPT header, but valid main header; regenerating
backup header from main header.
Warning! One or more CRCs don't match. You should repair the disk!

There's just the one OS on this disk. Possibly my changing the disk from
