Ubuntu problem, trying to bot

Hey guys. Well I recently got Ubuntu installed on my computer (using WUBI) and today I was testing it out. Well, it installed a bunch of updates and wanted to reboot, so I let it. Once it gave me the the screen for windows 7 or ubuntu, I selected ubuntu. Then I got a black screen saying this :
Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else, TAB list device or file completions.
grub>
grub>

Does anyone know how to "fix" this or bypass it or whatever I need to do, to go back to my normal desktop screen?

Thanks!

 

Not runescape cheating...You want tech support.

 

Just turn your computer off by holding the power switch for 10 seconds then turn it back on and select Windows 7 then uninstall WUBI via Uninstall A Program and reinstall it, The update could of crashed it so just try it again.
