Wubi won't boot

[PJAMA]

Help!

I installed Ubuntu 10.04 on my Parent's computer with Wubi, and It wouldn't boot up. It showed "Select Options in 3 2 1 0" then after that the CRT monitor kept turning on and off and wouldn't boot. My Parents have a Compaq Presario with Windows XP Media Center Edition with nVidia graphics card. I chose a 20GB Install. What should I do?

What you SHOULD have done is investigate problems with Wubi 10.04 BEFORE forcing an install on someone else's computer ...

Go to the Installations forum and read the pinned thread on Wubi 10.04 testing. You will find some problems that others posted along with some fixes.
