Computer apparently repaired
May. 27th, 2022 06:13 pmFollowing my previous entry on my computer issue: there's a reason I bought the on-site extended warranty. Annoyingly, I keep buying such shortly before an unplanned move, then finding it applies rather less in the next country. The timing of this particular incident was good, anyhow. The repair engineer sat at my dining table and replaced the mainboard, now I don't see any odd symptoms so perhaps all is now well.
It all went less smoothly than it could have, thanks to Windows, of which vestiges remained. After the mainboard swap, I could no longer boot into Linux. We fussed with BIOS options, I deleted more Windows via a live image from USB, we swapped the old mainboard back in, etc., but no luck. At least, from the live image, I could see that the system could see the installed drive.
Eventually, after I'd released the repair engineer to their next job, I managed to get the computer booting again: I had a Devuan rescue disk apply grub to the drive. I surmise that the earlier boot failure that moved directly into some Windows-looking-thing
I am glad that the IBM repair engineer saw the computer booting fine before starting their work. They were also gracious about the fact that neither the SSD nor the RAM are OEM.

repairingthe disk (without seeking any confirmation) actually broke it by overwriting the previous boot sector.
