Hello fellow ubuntu users,
I am using 20.04 on this computer. it was shutdown normally and next day did not complete boot sequence. I tried using a start up disk to do boot repair, the dump from that utility is here: https://paste.ubuntu.com/p/StNQQcQFvK/
The following lines in the log on the URL above look suspicious to me - line #67 thru #73:
grub-probe: error: cannot find a GRUB drive for /dev/sdd1. Check your device.map.
Unhide GRUB boot menu in sda2/boot/grub/grub.cfg
An error occurred during the repair.
You can now reboot your computer.
Please let me know if you need more details, I will provide.
thanks for looking.
