How do you remove the grb (grub 1) mbr from inside Suse Linux 12? I have tried this as stated numerous places on the internet (sda is my one and only drive), however it just says 0 byte written and has no affect

dd if=/dev/null of=/dev/sda bs=446 count=1

This question came from our site for professional and enthusiast programmers.

try this instead

dd if=/dev/zero of=/dev/sda bs=446 count=1

dev null produces no data, just an EOF. /dev/zero produces all zeroes.
