HD Install :: GRub

Hi can someone help me install Xp using the grub command line.
I have no idea.
We had red hat installed on this computer and I'm trying to put windows XP back on.
How do I do with with the command line.

I tried doing the CD rom boot but it stops after it gets to recognizing system hardware.

Thanks in advance

This sounds like this is a problem with your Windows CD, or your hardware.
