 Espérons que ça règle un peu le problème. Sinon je vais finir par faire une réinstallation complète et mettre une partition /boot de 2Go.:-\

+J'ai également rencontré un autre problème :

+grub-install: error: cannot backup `/boot/grub/i386-pc/ehci.mod': Structure needs cleaning.

+Si je comprends bien, il y a des erreurs dans les partitions et ça vaut la peine de nettoyer ça (voir [[https://askubuntu.com/questions/910078/structure-needs-cleaning-error-cannot-mount-partition|askubuntu.com]]) :
+<code bash>
+root@localhost-live:/#
