Decided to give Ubuntu a try using the stand alone wubi.exe. When I'm done installing, and rebooting for the first time, I only get a black screen with a blinking text input cursor, and my caps lock and scroll lock blinks.
After another reboot, I get this screen with image corruption.
I am using an Nvidia GeForce 580 graphics card on a ASUS P7P55D PRO motherboard running Windows 7 HP 64bit.
Press up, at least that is what works for me with my WUBI. Hope it helps.
