Ciao
ho un sistema con 2 hd il primo sata con installato Ubuntu, il secondo eide con Vista. Entrambe le installazioni sono avvenute staccando l'altro disco. Al momento quindi gestisco il boot di uno o dell'altro sistema da bios indicando quale dei due hd far partire per primo. Ora vorrei utilizzare un dual boot software come posso impostare grub per far si che mi riconosca anche Vista così configurato?

Grazie mille

Postalo qui, poi:
Ed anche questo. Così aggiungiamo anche la partizione di Vista e col bootloader partono entrambi i 2.

PS. Hai grub nell'mbr o il bootloader di Vista?

prova a fare così:

apri il file menu.lst:
e aggiungi le seguenti righe:
modifica anche "hiddenmenu" all'inizio del file, in particolare mettici "#" (un cancelletto) davanti...facci sapere se va.
