To copy the boot code in the MBR:

dd if=<old drive> of=<new drive> bs=440 count=1

Example:

dd if=/dev/sda of=/dev/sdb bs=440 count=1

Note that these are drives specified, not partitions (e.g., sda1, sdb1).

The "c:\ drive" is not a drive; that is common but stupid MS user terminology 
that isn't even consistent with MS technical terminology, which is "volume".
