Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I know this question has been already asked but I think mine is quite different because my Ubuntu is installed via wubi not Live-DVD. I'm using Ubuntu 12.04, and everything works fine, I have two portions, C for windows and D for data storage (and where Ubuntu is installed) I have run out of space on C so I extended it this tomorrow, after that Ubuntu refused booting giving error: no such device:"numbers" I have many important stuff on root.disk and I don't know what to do. please could someone tell me how to fix that? I have searched around I have found many methods and I don't know which one the suites me.
