    Hi Haines.

    Could you describe more acurately the situation? You have two
disks, each with an installed OS. I suppose your working system is on
/dev/sdb and your new, non-booting one is on sda. On which OS are you
running update-grub and grub-install? Let's clarify this before going
further. I would like also to know how you reach this situation because
it canhappen, but I've never seen that after a direct install from the
installer.
