I don't understand the syntax you are using, so I'll use what I know works...
You need to know which drive is being seen as #1 (GRUB will let you know if you guess wrong)
Lets assume Windows is #1 and Linux is #2
Also assuming that the Linux /boot directory is on partition 1 of drive #2
starts the grub shell
tells grub that /boot is on drive 2, partition 1---at this point grub will confirm that it finds a Linux filesystem there.
puts grub on the mbr of drive 1
Next, you have to edit /boot/grub/menu.lst
for the GRUB manual
