Dopo parecchi giorni sono ritornato a casa e metter mano sul mio pc fisso, e non so come di preciso - ho aggiornato il kernel, ho ripristinato il bootloader da livecd e sono riuscito a reinstallare GRUB2 - son riuscito a far aggiornare il grub col comando:
- Code: Select all
# grub-mkconfig -o /boot/grub/grub.cfg
Ora mi vede anche il nuovo kernel 3.5.0 . Tuttavia non mi carica lo spash screen (grub è in bianco e nero), e, cosa ben più grave, l'os predefinito di avvio è diventato windows7 (riconosciuto non perché come 8 ) e non più sabayon.
Come posso fare? Non so dove mettere le mani, però intanto vi posto i miei /etc/default/grub e /boot/grub/grub.cfg perché ho letto su vari forum che in genere sono loro che creano problemi.
/etc/default/grub
