Okay.
Please check and post the Setup settings for the disk drive.
Please run and post:
# gdisk -l /dev/sda
root@courgette:/home/mick# gdisk -l /dev/sda
GPT fdisk (gdisk) version 1.0.9
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!
Main header: OK
Backup header: ERROR
Main partition table: OK
Backup partition table: OK
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: damaged

Caution: Found protective or hybrid MBR and corrupt GPT. Using GPT, but

verification and recovery are STRONGLY recommended.

There's just the one OS on this disk. Possibly my changing the disk from
MBR to GPT caused some error.
I will take everything to bits but I am doing important shit-posting work.

Thank you for the gdisk(8) output. I do not see anything notable beyond
the backup header warning, but factual information will provide clues
for the experts on this list.
When you say "my changing the disk from MBR to GPT", could you please
describe this in general terms and also please post the console session?
Perhaps there are more clues in there.
David
