Ubuntu will not boot (dual boot win7 and 10.04)

[804mini]

I have the option of selecting between win7 and Ubuntu during start up, but when i select Ubuntu it goes to the first 2 lines of command and then restarts again. Windows 7 works fine. This is the second installation of ubuntu on this computer, the first attempt did the same thing (would not boot into ubuntu but win was fine) after i lost power. This time i shut the computer off for a full week while i was on vacation. I have switched between windows and ubuntu a couple of times and had no issue with this installation.

See the Wubi megathread (http://ubuntuforums.org/showthread.php?t=1639198), problem #2, Solution #1. Once it is booting, apply the Permanent Fix.
