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.
This usually happens when you update grub from the wrong OS. Can you unplug sda, boot
again. If it works, doublecheck the boot entry in the bios. If it's efi and you have 2
efi partions on your system (each on a different drive) try to get rid of the one you
don't use - should be sufficient to change the partition type.
And move your boot device from sdc to sda --> swap sata ports.
Nik
