When I try to boot from my Hard Drive I get a blinking white unerline cursor and nothing else (it does go tthrough the "press F2 to ... screen ok).

I had other hardware problems previously and transfered this HD to another PC where it was working well for some time until I started getting some kind of odd "ethernet problems ... check cable" erorrs then the boot problem I mentioned above. I go the original machine working and put the HD back in it with the same no boot problem.

THis is a laptop running Windows XP Pro.

How can I get my data back?

Thanks for any help!
