OK the grub thing can then be done very easy. Go up in the Rescue mode 
and when up, type grub at the prompt.

    Now when in grub type exactly:

grub> root (hd0,0)
grub> setup(hd0)
grub> quit

This is what should work now that you tell us the exact partition for 
/boot/.

Please tell us what happens?
