Bonjour,

a la fin de l'installation de fedora il me sort le message suivant :
une erreur est suvenue lors de l'installation du chargeur de démarrage. le systeme ne sera peut etre pas demarrable
et effectivement quand je redémarre après l'installation le system ne démarre pas, et me sort le message suivant:
BootDevice Not Found please install an operating system on your hard disk
j'ai même essayer avec boot-repair-disk, mais rien. en voila le log de ce dernier:

j'ai crue au début que c'est un problème de disque, pourtant quon j'installe open suse12, ya pas ce problème de boot !!

merci de votre aide
Is device-mapper driver missing from kernel?
Il y a ça qui m'interpelle mais est ce que ce n'est pas dû au fait que tu bootes avec un systeme basé sur Debian ?
Essaie de démarrer alors avec un dvd d'installation de Fedora en mode réparation.
j'ai déjà essayer, avec les commandes suivantes:
chroot /mnt/sysimage
grub2-install /dev/sda
et ça me sort:
path '/boot/grub2' is not readable by grub on boot.installation is impossible.Aborting.
ça a tiré par les cheveux tous ça !!!

Oui mais je ne vois pas de raison d'effectuer le chroot /mnt/sysimage.
quand j'entre juste la commande
grub2-install /dev/sda
ça me sort:
/mnt/sysimage/usr/sbin/grub2-install: line97: /usr/share/grub/grub-mkconfig_lib: no such file or directory
