I have just re-install Windows XP after a big boot problem.

In the operation I have lost all my desktop and 1 GO of data files!!!! (I can't have saved those files on another repertory because I can't have run Windows)

I search a program such as "undelete" to restore erased data files working with NTFS partitions. All programs I have work only on FAT partitions :-[

Help me please.
