[tde-users] SDD puzzle

Hi, everybody! (I hope you hear Dr. Nick's voice when you read this line.) My SDD boot . . . isn't booting. Here's how it unfolded: I popped the side off the case so as to install a couple of top-facing exhaust fans, controlled by the motherboard, bring the total case fan count to five (two intake, three exhaust), because with that many fans none ever really spins up, so the computer is next to silent. That's all I did in there. I came nowhere near anything having to do with any of the drives. When I fired up the computer again I got the usual GRUB menu, the second item of which was the 20.04-LTS installation on /dev/sdc1. I chose it. And it booted forthwith -- to the 20.04-LTS installation on /dev/sda1. No errors, nothing. Just booted the wrong drive. The SDD (sdc) is working fine -- I can mount it, navigate in it, read and write to it. Any troubleshooting ideas that don't involve disassembly? This was working fine yesterday and isn't today. -- dep Pictures: http://www.ipernity.com/doc/depscribe/album Column: https://ofb.biz/author/dep/
