Hello Friends!
Desktop Computer One has a hard drive that is multiboot: Windows 7, Debian, and another linux operating system which I will call linux-x.
It seems that the MOTHERBOARD of Desktop Computer One has finally given out (wild guess only, as even a linux live USB can't function properly). I took out the multiboot hard drive and put it in another desktop computer which I call Desktop Computer Two.
Now I can boot into linux-x just fine with Desktop Computer Two. I'm using linux-x to type and send this email. I have not tried the windows 7 yet.
However I cannot boot into Debian (I believe it is Debian 10). I get this message:
-----------------
You are in emergency mode. After logging in, type "journalctl -xb" to view
system logs, "systemctl reboot" to reboot, "systemctl default" or "exit"
to boot into default mode.
Cannot open access to console, the root account is locked.
See sulogin(8) man page for more details.
Press Enter to continue.
-------------------
If I press enter, I reach the Debian logo with the circling animation but after a while I get the above message again.
If it matters, the UUID of both / and /home partitions of the Debian system remain the same; I compared the info provided by Gparted and the /etc/fstab in the Debian system.
Thank you for your time.
