I decided to switch my PC to a dual boot using Ubuntu 7.10, and have run into a little snag. I installed Ubuntu on its own partition with little problem (it already existed, I didn't have to make a new one). However, now when I try to go into Windows XP, it takes me to the login screen, but displays no user name to click on for logon. So now I can't use Windows (safe mode doesn't work either). Has anybody seen this before, and does anyone know how to fix it??
