I've been using grub-legacy to boot grub via the bootrecord of an extended

somewhat weird setup I've got (one button boots the mbr, another button
boots the grub-associated bootrecord)
In grub legacy it was a simple matter of specifying to install to (hd0,3)
(or sda4). But in the new grub2 this no longer works and just gives
"grub-setup: error: no such partition" or "Invalid device `/dev/sda4'".
I've tried grub-setup with --force but no luck.
Is there any way to use the grub tools to do this, and if not, are there any
way to do it in a more manual fashion and create the bootrecord image
correctly and then simply dd the image onto sda4?
This is the fdisk output, goal is to have the "mbr" (br) on sda4 boot grub
files from sda6

Have you tried using (hd0,6) and installing to the area at the start
of your linux filesystem?
Problem is I need it on a primary (Boot-button can only boot primaries).

I did actually find A solution, but it's wonderfully kludge-tastic:
I simply wrote it to a logical partition and dd:ed over the 446b
bootrecord to the extended partition, and lo and behold, it works.
Well, it's ok for the time being, but it would be quite nice if there
was a more "proper" method to do it..
