However, if it has the common 3 partitions (/boot, / and swap) then you can create partitions as you wish, tar the first two partitions, and then use dd to copy just the MBR. Finally there is a command to initialize the swap partition, you can wait until the copied system is up to do that. You can find the dd commands to copy the MBR with a Google search.
