conoscenza ha scritto:Il problema è che il boot di Gentoo dipende dal grub di Salix. Come ti consigliavo tempo è meglio creare la cascata dei grub con il chainloader.
Ma qual'è il problema?
Da salix, da root, prova a ridare:
update-grub2
e posta qui i risultati.
Con il 2 non funziona.
E' andata peggio. Adesso non ha visto affatto la presenza di Gentoo.

Come prima.
Anche la prima volta, quando ho aggiornato il kernel di Salix e dato update-grub, sembrava tutto O.K., ma il risultato è sempre questo.
Poi, non hai risposto alla domanda se è sicuro che il kernel di Gentoo lo va a cercare nella partizione /boot di Gentoo e non in quella di Salix. Se lo cerca in quella di Salix, è ovvio che non può trovarlo.

Al posto di quello che hai per avviare Gentoo...
Salva, riavvia, seleziona Gentoo e poi riportami quello che vedi....
