Important point; perhaps he just wants to get rid of the MBR on one partition in which case he might use fdisk to eliminate that partition and then recreate it ?? Any way to dd just one partition (e.g., dd if=/dev/zero of=/dev/hda1) ?
edit: I'm guessing the MBR gets placed at the top of hda regardless of what partition the boot files are in (thus dd if /dev/zero of /dev/hda count 1 for removing it). In that case, getting rid of the boot partition wouldn't solve anything (except produce an error about not being able to find the boot image).
