ciao a tutti, piu' o meno mi succede la stessa cosa e questo e' il risultato:

[root@localhost guest]# grub-install /dev/hda
Probing devices to guess BIOS drives. This may take a long time.
You must set the root directory by the option --root-directory, because
/boot/grub does not exist in the root device Could not find device for /boot.

non riesco a capire... cosa devo fare?
