Just installed Ubuntu 12.10 (wasn't 100% happy with 13.04 yet) from a USB drive. I have done this numerous times. This time I did the install three times. I think something was wrong with one flash drive, and the installation hung, so I reinstalled WUBI onto another USB drive and did this install again (wiping everything out each time). After this install, the computer doesn't boot, and all I get is a black screen with blinking cursor. So I did another fresh install thinking something strange happened, but in the end I got the same result. I have a Dell Vostro A90 with a runcore 32GB SSD and 2GB ram. I have been using Ubuntu full time on this computer since 11.04 and figured it was time for a clean start. I'm going home to play with it some, but if anyone has any ideas, I'm obviously not making a lot of progress here.
