 * Using MS-DOS/Windows 9x boot disk
   * In order to remove the GRUB bootloader from a Linux and Windows XP machine, boot with a Windows 9x startup disk or CD and execute the MS-DOS command:
{{{
fdisk /mbr
}}}
 * Using Windows XP boot disk
   * Boot computer using Windows XP (Windows 2000) setup disc / CD / DVD. Next, type the following commands:
{{{
# fixmbr
# exit
}}}
 * Using Linux
   * You can also use dd command from Linux itself (it removes partition table):
{{{
# dd if=/dev/null of=/dev/sdX bs=512 count=1
}}}
   * Just remove MBR, without the partition table (see comment below):
{{{
# dd if=/dev/null of=/dev/sdX bs=446 count=1
}}}
