Another issue I've had recently relates to partition alignment.
I had old drives that were formatted with 32Kbyte partition offset.

That rang a bell with me. I had a system refuse to boot due to the
allocation unit size. I'd tried using a large size for a partition I
used for backup and it did the power off and try again thing even
though the boot and system partitions hadn't changed. This was with
Windows 10 but it wasn't getting far enough to attempt the boot if I
remember correctly.

Good info, but I'm pretty sure alignment isn't the issue. I'll keep it
on the list, though. Thanks.

No, I think you've eliminated that as a potential problem by now, good
luck.

Yeah, so far it seems like it was a vcore voltage issue all along, and I
was simply too ignorant to recognize it. I saw that voltage numerous
times while staring at the BIOS screens over the past few weeks and it
never occurred to me that it was too low.
