Delete MBR Code, using: FDISK /MBR
It is very safe to write MBR directly using grubinst or bootlace(even to the wrong drives), because grubinst and bootlace will keep partition table untouched. But remember, you are to write MBR, so do not write to a partition by mistake.

Backup Boot MBR, you have another chioce of doing this work in 3 steps(Note: this is a manual install using bootlace and an other disk capture utility):

1. capture your MBR 64 sectors(63 sectors in the beginning track, plus one sector of your first partition) and save the file as MYMBR. If you do not intend to install MBR onto your USB drives, you may capture only 18 sectors of your harddisk for the MYMBR. You may save this file to another disk in case you would have your disk damaged.
   
2. At the DOS prompt or in a Windows CMD box or under a Linux shell, type this command:
   
   bootlace.com MYMBR
   
   This will write the GRUB4DOS MBR onto the file MYMBR. You may check the content of this file and make sure the partition table in it not destroyed by bootlace.com.
   
3. write back the MYMBR onto your original disk. Don't write to anthoer disk because the partition table will also update! Serious!!

grub.exe(for running under DOS or other bootloaders like SYSLINUX or LILO)

Both grldr and grub.exe are the grub4dos boot manager.
bootlace.com, instead of grubinst_gui, can also be used to write MBR code.
