Thanks for the suggestion. I have reformatted, and copied the three kernels I use back to it. In a little while I'll get up the nerve to try it out, first to be sure I can still get 12.04.
Also, you can make a small FAT partition on the HD and boot from that. Then your root would be sdx2.
This is over my head. Currently I boot with root as /dev/sdb1, presumably because that is where Ubuntu 12.04 LST resides. What would I put on sdx2? And should I interpret sdx2 as /dev/sdb3, in light of the fact that I have sdb2 full of Ubuntu 15.10 files?
I'll just add here: 12.04 boots fine, /dev/sdb2 gets the previously reported message. I didn't add the rest before. After the Kernel panic line is this stuff:

I think it still means "Install 15:10 again from scratch."
