I had ubuntu and it stopped coming up on boot. I have tried to save root.disk file on external hard drive three times, it freezes on 62%. I tried zipping file, it freezes computer about half way. I have deleted anything to do with ubuntu and still the wubi install gives me an error and says to go to a log file that does not exist. I have tried the cd, which I downloaded and on install when it goes to the box of which I am to choose what space to put it in, it gives me an error and tells me to choose root file from parameters. Anything I choose it reverts back to original box. I can't install. Help!
