Im trying to run the repair function (press R at the menu thing) and it's asking me for a password, that does not exist, I've used the cracking disk to check, came up with "empty" aka, No password. pressing enter with nothing entered just opens up a dos line....

On my non-functional computer, I ran a Windows XP Home Edition, this morning I was on it when my system froze, so I rebooted it, before it could get to the Windows XP loading screen, the error message: NTLDR Not detected, please press CTRL+ALT+DEL to restart. Obviously the restart did nothing, so I booted the system with my Windows XP home edition disk, and tried to access the recovery repair console, it asked me which system i wanted to load, with only 1: C:/WINDOWS listed, so obviously I chose it... It then asked me for the administrators password. I had none set, after running an image disk designed to crack the administrators password (OPHCrack) I was reinforced that I did NOT have any administrator password, and password Possible I tried, and entering nothing did nothing but go to the next line, like any normal DOS window, I even tried LOGON 1 with no password entered, but it still asked me for another password. Is there any command to bypass/fix this? or do I have to rebuild my computer from scratch again? (I would REALLY rather not.)
