    Exclamation Kernel Panic After Incomplete On-Line Installation of 12.04

    I clicked the "Upgrade to 12.04" button in the upgrade manager, and the installation stalled at about 80% (2 hours to go), right in the middle of the machine installing some MS font-related files. The two things I noticed from this point were that I had no options to stop or retry the upgrading process, and some of the windows I was using had no text in them, only vertical rectangle characters.

    Upon restarting the computer, I got this:

    error: no module specified.
    error: no suitable mode found.
    error: unknown command 'terminal'.
    [ 1.205753] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

    That's it, and a blinking cursor. I can boot from a live CD; is there a way I can make the system fix the installation?
