So, if one did a dd backup of the boot sector and the embedded area
before the first partition, is there a tool that can replace those
sectors but do it safely. E.g. Only replace the number of sectors that
fit before the first partition, and preserve the current partition
table, and not use the partition table from the dd backup.
