Bonjour,

alors j'ai réussi à resoudre mon probleme. Sur mon disque dur externe, la 1ere partition etait en NTFS et non bootable, la partition linux etait installée ensuite.
Apparemment c'est ca qui posait pobleme au GRUB.
Alors j'ai déplacé la partition NTFS vers la droite, puis j'ai réinstallé ubuntu au debut du disque (avec le GRUB installé sur la partition racine de linux), et suite à ca tout marche parfaitement, je n'ai rien eu à modifier ni à éditer.
