Grub
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
Altro esempio GRUB Le cose fatte sono state le seguenti: 1) Boot con tomsrtbt linux. 2) Mount della root di linux (hda3 nel caso) sotto /mnt/hda3/ 3) chroot /mnt/hda3 4) /sbin/grub

5) exit 6) umount /dev/hda3 7) reboot
