OK I did that and this works.

## At the GRUB boot menu, hit c to get to a shell
grub> root (hd0,0)
grub> setup (hd0)
grub> setup (hd1)

That's it.

What I did to test is was I zero'd the first 440 bytes of vdb and the
the first 512 bytes of vdb1. I confirmed that this disk alone does not
boot at all. After running the above commands, either drive boots.

NOW, I get to say I've seen stage 1.5 get used because when it did the
setup, it said it was embedding /grub/e2fs_stage1_5. In the above case
hd0,0 is first disk first partition which is /boot.

Anyway, this seems about 8 million times easier than linux
grub-install CLI. Now I get to look back at OP's first email and see
if he did this exact same thing already, and whether we've come full
circle.
