The MBR (first 512 bytes) contain both bootloader and partition table.
The Bootloader is in the first 446 bytes the remaining 66 bytes contains
the partition table... I suppose you could try zeroing out the first 446
bytes.
# dd if=/dev/zero of=/dev/hdX bs=446 count=1
*Warning* I have never tried this before.. and this solution comes with
absolutely no warranty whatsoever! (Not even sure if a virgin MBR is
filled with zeroes)
Take a backup of the whole mbr before trying it out.
# dd if=/dev/hdX of=/path/to/mbr-backup bs=512 count=1
You can restore it with
# dd if=/path/to/mbr-backup of=/dev/hdX bs=512 count=1
If you do try it out... and succeed .. do let us know so that we can add
it as uninstall instructions.
