mkdir disk
mount /dev/sda1 disk # sda1 deve contenere la partizione root e la partizione boot
- mount /dev/sda2 disk/boot # solo se la partizione di boot è separata
 
mount --bind /dev/ disk/dev/
mount -t proc none disk/proc
chroot disk /bin/bash
grub-install /dev/sda # se il disco su cui installare è sda
