This is not advice for your problem, I just wanted to
point out something I noticed. Your description of the
two grubs conflicts with my understanding of them. As
far as I know, the following is true:

    grub1 = grub-legacy
    grub2 = grub-pc

So, in my understanding grub1 != grub-pc. That alone may
give you a way to understand what grub-pc is asking you.

Hope this helps,
