I am on a Toshiba Satellite laptop. I started getting this error and am unable to get this thing to boot. I tried using the system disk that came with the machine but it didn't work. It went through the whole recovery process and when it tried to reboot, same error. I do not have a windows XP specific CD. I didn't get one with this machine. Just the system recovery disk, so the whole put-cd-in-and-hit-r-for-repair doesn't work either. Any suggestions welcome.
