Nils' explanation regarding to the OP's needs is better than mine, but
for good reasons, I gave this MBR explanation and mentioned to take a
look at dd --help. To be fair, with my broken English the explanation of
the "bs" option is disgusting and it might be not understandable for you
dd is a powerful tool, you are missing the "bs=512" :).
