Hard on folk today. You can google HOW TO INSTALL XP TO A SATA DRIVE to learn the usual methods but you find that most folk are wiped out and can't do any of the methods today since they don't have the right floppy drive or don't want to do the 5 week install method.

It could be as simple as a BIOS change but your post has no make or model noted so I was not able to see if the BIOS has support for XP.
