Operating system

Hello,
Sir/ma,
I was talking about the new hard disk I was loading on older system that was telling me to change the stand alone slave to master. You have solved that through your previous reply. The system is pentium 4 and I was trying to load window xp service pack 1 but it has been bouncing back to beging again after it has copied the necessary file on restarting. the hard disk is 80GB. Please help me out.
