Acronis Rescue Media
 

Yesterday I made a change in the XP registry,(changed the drive letter)backed it up before the change.Rebooted the computer,but I wasn't able to log in.Windows will advance up tp a point and stop right before the log on screen.
I used the "Acronis BootableRescue Media"which was made a few hours earlier.Same thing no help at all.
I couldn't log into safe mode either.Any ideas?.BTW,I did a fresh installation,
