Bad, *very* bad.
This over-writes the NTFS partition, not the MBR.
I tried uninstalling GRUB by booting from Windows XP CD but I don't see that partition at all to log in and use FIXMBR. Is there any other alternative to recover this drive or have I lost all the data?
Try fixboot first, followed by fixmbr.
If you're lucky you'll be back in business.
Your data is still there, you just need to be able to get at it. See how you go with the above.
D'oh, slow typer ...
