In order to move objects of similar sizes between 2 locations, you need 3 locations total : 1 destination, 1 target, and 1 temporary. Similar ideologies apply here. You need to a) dump(3) the data from your FreeBSD disk into a safe spot, and b) copy over all of your Windows files into (another?) safe spot, then, c) install XP over from scratch with the new scheme, and d) boot using a freebsd snapshot iso, copy all of your files over again by "un-dump(3)'ing" them, and modify /etc/fstab accordingly.
