After upgrading from 8.04 to 8.10, it apparently locked out. My attempt to unlock yielded a black screen after which I quit X using CTRL+ALT+BACKSPACE. At which instead of going back to the log on screen, it restarted (didn't go to the bios however) and froze, at which I performed a hard reset (held the power button). I started the upgrade the previous night, so it should have finished upgrading...
Now, when I select any ubuntu from the Grub list, it returns a Error 15 File Not Found
So, it's obvious that I broke it, is there anyway to fix it?
