I already considered that, but there are a couple issues with that assumption: 1) Right after moving 18.04 to the new Thinkpad I did not have this error. But it did appear before I did the dist-upgrade from 18.04 to 20.04.1. If I recall correctly, 18.04 was copied from the old computer at the Clinic in December, 2019, and the grub error did not occur until the middle of the summer, and the dist-upgrade to 20.04 had to wait until Ubuntu released it for upgraders, in late October. 2) I read through (many pages) of /var/log/dmesg with Mousepad and didn't see any error messages that looked like they might have something to do with grub. I was also especially interested in seeing if I could find an explanation for why the computer takes so long to boot - over 30 seconds, when all the local drives are NVMe. I also searched the entire file for 'grub' and found nothing. This is a grub error, so it should have something to do with booting. Maybe there is another log of messages I should be looking at. _______________________________________________ PLUG: https://pdxlinux.org PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
