Je suis un peu perdu en fait :s
En gros il faut que je fasse cela:
apt-get install grub-pc # installation du logiciel Grub2 (sur le disque maintenant à la racine)
update-grub # création d'un nouveau fichier de configuration : grub.cfg
grub-install /dev/sda # installation de grub sur le MBR
c'est bien ça ?
Cependant, qu'est ce que je dois faire exactement avant? Sachant que j'aimerais avoir /dev/sda7 au démarrage de grub ainsi que /dev/sda2 (windows)
Pour info:
