Antonio:
>From the grub prompt, grub sees the /boot/grub/grub/conf as coming from
(hd0,0)/grub/grub.conf.  It's a function of how grub refers to
partitions and drives, since the whole file system isn't mounted, the
first partition isn't mounted under /boot so the file system on the
first partition only contains a grub sub directory. Confusing, yup!
