This question already has an answer here:

I used the wubi to install ubuntu beside windows a while ago and decided that it was time to take the step and upgrade. After I did, and everything went fine, when the computer started up it went to the purple start screen as normal then black.............for ever.......

I am afraid to download 13.04 and install it in case I want to upgrade to 13.10 when it comes out for the fear of the screen....

what would cause this?

its literally right after the upgrade and right after the start up purple screen. This upgrade is only a distro upgrade, doing regular updates is fine.

What graphics card do you have? Have you tried nomodeset? Have you tried an older kernel? – bcbc May 25 '13 at 23:58
i cant do anything, I have a Sony Viao with a AMD Radeon HD 7550M/7650M Graphics. Like I said, when the machine boots after a distro upgrade I get: "Which OS do you want, windows 7 or Ubuntu" after that, puple screen, then black.......usually after the purple screen I get the login screen. it pretty much comes dpown to me booting into windows and using wubi to uninstall linux. – TheWebs May 26 '13 at 0:02
Hold down the Shift key after selection Ubuntu and the Grub menu will pop up. – bcbc May 26 '13 at 0:05

This may be an issues of screen brightness. Once I upgraded to 13.04, my screen was pitch black as well, but I just turned the brightness up with a function key. Hope this helps!
