Quick showstopper: are you sure you want only two partitions? Most people would advise on an FAT32 (aka vfat) partition for your personal documents and other data, which can be read and written to without problems by both linux and windows xp, while you'll want your windows system partition to be the win xp default, ntfs.
As for the problem you asked about, is it the same as this thread:

If so, you may want to contact the user and ask what the fix was.
