I wouldn't use dd for this. Gparted has been more helpful to me in a
situation similar to yours. Using Gparted (a) I'd  first create a NTFS
partition (make sure to create it As Primary),
(b) copy the partition from the source drive to the target drive, and
(c) if there's
a problem booting the target drive with xp in it, use a winxp cd to go into
rescue mode and use FIXMBR to fix the master boot record.

Gparted copies partitions pretty well.
