Hello, I was changing the registry to try and fix a problem with my USB flash drive when I somehow screwed up xp such that it wouldn't boot normally (even in safe mode). So I then put in my XP install CD and ran system repair. After repair finished it booted XP, however, right after the XP boot screen I get the blue screen of death. Everytime, and in Safe mode I get "setup cannot continue/finish in safe mode". I've tried running repair again but I get the same error. I have also tried running CHKDSK /R from the recovery console. If it helps, the computer had Windows XP Pro Service Pack 2, the setup CD incudes win. XP Pro with service pack 1. Thank You!
