Old harddrive, new system

[PlatinumDragoon]

I took the harddrive from my dad's computer and put it into my old box. My old system is a Intel P4 on an Intel board. It has 1 gig of ram and a new power supply. In the bios, the board sees the harddrive and everything else.

However, windows Xp will not load in any mode. A window comes up says that a hardware change is resposible.

Without reformatting, how do I bring Windows XP back online?

Thank you for any help.

Platinum Dragoon.

Not sure you can, but you could place it in another system to retreve lost files .
