Erreur boot (kernel panic) HP ProBook 6460b

Bonjour,

J'ai procédé à une mise à niveau vers Ubuntu 16.04 sur mon pc HP ProBook 6460b à partir d'un Live USB. L'installation a fonctionné, j'ai ensuite redémarré une fois le pc, fais les mise à jour des logiciels avec succès, puis tenter de faire les mises à jour système, cette fois l'ordinateur a planté. Au redémarrage suivant impossible de lancer Ubuntu, j'ai une erreur de type :

 end kernel panic - not syncing VFS unable to mount root fs on unknown-block(0 0) 

J'ai effectué un Boot-info à l'aide du Live USB :

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to) and reinstall the grub2 of sda1 into the MBR of sda.
Additional repair would be performed: unhide-bootmenu-10s


=================== User settings
The settings chosen by the user will not act on the boot.

Il n'y a que 5 Go d'occupés sur ta racine à home inclus.

  Soit tes données ont été effacées,
et alors tu arrêtes tout pour te concentrer sur la récupération des données, en évitant surtout de démarrer sur ton disque interne ;
  Soit tes données n'ont pas été effacées,
et alors le plus rapide est de sauvegarder sur DDE le peu de données que tu as,
et de procéder à une installation fraîche.

Re : Erreur boot (kernel panic) HP ProBook 6460b

J'ai tout sauvegardé sur DDE avant l'installation. Et j'ai choisi de formater avant de réinstaller.

Re : Erreur boot (kernel panic) HP ProBook 6460b

Et après réinstallation fraîche,
puis mises à jour,
le système redémarre bien ?
