Question Remove MBR in linux FDISK

is there a way in linux fdisk or cfdisk or something else, to delete the mbr? in dos fdisk you can use /mbr and it will erase it supposedly.

Delete your MBR? Make sure you really want to do that. The DOS command "fdisk /mbr" will REPLACE THE BOOTCODE, it won't DELETE THE MBR. Two entirely different things, one being potentially disasterous. Be careful what you ask for.

The only method I know of is dd---as in:
dd if=/dev/null of=/dev/XXX bs=446 count=1 where "XXX" is the id of your drive--eg hda, hdd, sda (note no partition id---just drive)

To wipe out the partition table also, change 446 to 512.

BUT--as the man said: Be really sure that this is what you want to do!!!!!
