I wanted to upgrade my system from 14 to 15, so along these instructions, I changed the line to Prompt=normal and ran the upgrade command. A couple of hours later, I decided to reboot and check out the new ubuntu. However, it froze on shutdown, and I had to do a hardware shutdown. And when I tried to reboot, I got the /sbin/init missing error. I tried many of the other solutions, but none worked.
And when I booted with a GParted live CD, and mounted my old file system, I saw that all my files were intact.
However, my /sbin/init and /sbin/shutdown were actually missing.
What should I do to get my system back and running? I can get a live/installation CD if need be, but don't have one on hand.
