Perhaps we forgot to mention that the word on Mister Laptop (what is his blog name again?) is feeling much better, thank you!

I did reinstall the OS and that left all of the files in place, but the next two reboots both crashed. This was not encouraging. But I tried a few different things, including logging into my backup account, and I was able to get the upgrade OS installation done. And it hasn’t crashed since! ::knocking wood::

So maybe the thread of the shame of restoring backed-up files was enough, but he’s back and feeling great! Yay!!
