Had the same problem...made a BartPE disk, and at first I didn't think it was working either....because I was still being emediately logged out. However, the problem is that I was trying to enter the original PW to logon. This isn't necessary after you use the BartPE disk. The PW is no longer there. So you need make sure when you go back to login to your computer that you DONT enter a password after running BartPE...just hit enter and you should be able to log right on to your computer!
Making the BartPE turned out to be the most frustrating part of this whole nightmare process, but I'm just thankful I was able to get back into my computer without having to completely reinstall everything and wipe my computer!
