<p>No, gparted moves filesystems. It may or may not move the partitions boot sector, but the MBR is a definite no-no. The MBR can, however, be manually copied, so long as only the code segment and not the partition table itself is copied. See the wikipedia article for MBR for the layout of the MBR. If memory serves, code is the first 440 bytes of the MBR but I am not 100% certain of that.</p>
