Faire booter grub sur une image iso
salut,
Voici comment faire booter grub sur une image iso sauvegardée sur le disque dur.
Il y a un outil grml-rescueboot pour créer le menu grub, voir la doc en anglais:
https://help.ubuntu.com/community/Grub2/ISOBoot
Exemple:
Installer grml-rescueboot:
sudo apt-get install grml-rescuebootMettre l'image iso dans le dossier /boot/grml/
@ubuntu-desktop:~/Downloads$ sudo mv raring-desktop-i386.iso /boot/grml/
[sudo] password for : Regénerer le menu grub
@ubuntu-desktop:~/Downloads$ sudo update-grub
Generating grub.cfg ...

Found initrd image: /boot/initrd.img-3.2.0-36-generic
Found memtest86+ image: /boot/memtest86+.bin
Found Grml ISO image: /boot/grml/raring-desktop-i386.iso

Et hop un petit boot sur l'image iso de Raring pour tester. Il m'a fallu mettre le clavier français dans les propriétés systèmes
