I like what WhiteChedda says.

I suggest first fix your WinXP by MBRFIX or a reinstallation and see
if your data even still exists. The Windoze system must be installed
first anyway
If MD has created new partitions, leave them so you can use them
for the Linux reinstall. You will need these partitions anyway.
(if you have Partition Magic you can check first)

After fixing XP, if the data exists and the partitions are there, just reinstall
MD to the linux partitions.
There should be two, ext2 or ext3 and a swap partition.

MD (in expert mode)will ask you if you what partitions to format
and how to format them (type of partition(ext or swap)) Do not format
hda1, that is the Win partition.
That may be what you did and now your data is lost.

This is only my opinion.
Mandrake has been good to me and I ain't that proficient.
It will do what you tell it and if you screw up, it will too.

My opinion about XP is that it seem to be the most successful
virus ever.
