Plus de Grub au démarrage (RESOLU)

Bonjour à tous,

j'utilise un portable avec un dual-boot windows 8 et Kubuntu 16.04. Jusqu'à mardi dernier, tout fonctionnait bien.
En voulant démarrer mon PC, je n'avais plus le menu du Grub, seulement le message suivant :
"All boots options are tired.
Press <F4> key to recover with factory image using recovery or any other key for nect boot loop iteration"

J'ai pu redémarrer l'ordinateur avec une clé USB bootable et j'ai pu vérifier que mes données sont toujours là ! (ouf !)
J'ai essayé de réparer le Grub en utilisant Boot-repair, mais cela n'a rien changé.
Je peux toujours essayer de réinstaller Windows 8 et Kubuntu, mais vu le temps que ça va me prendre, je ne suis pas motivé !

Quelqu'un a-t-il une meilleure idée ?

Merci.

Re : Plus de Grub au démarrage (RESOLU)

Bonjour,
Je te prie de démarrer ton ordi sur une LiveUSB de Kubuntu 16.04 en sélectionnant "Essayer Ubuntu" ("Try Ubuntu without installing" si c'est en anglais) afin de faire une session live. Tu feras un Boot-Info depuis cette session live en suivant les indications du paragraphe 1.2 Cas où aucun ubuntu installé sur disque n'est opérationnel. Tu donneras l'URL de ce Boot-Info dans ta réponse.

Edit : ce serait utile que tu donnes également le nom complet du modèle de ton ordi et son fabricant.

Re : Plus de Grub au démarrage (RESOLU)

Bonjour malbo,
merci de m'aider. J'ai suivi tes conseils : j'ai installé installé boot-repair et voici le lien vers que tu m'as demandé : http://paste.ubuntu.com/26140880/

Pour ce qui concerne mon pc,  c'est un portable Samsung NP370R5E-S02FR ; Intel Core i5 ; RAM = 4 Go.
Lors de ma 1ère installation de Kubuntu, j'avais écrasé par mégarde la partition de restauration. J'avais par la suite réinstallé Windows 8 et Kubuntu 16.04, tous les deux en 64 bits.

Merci.

Boot successfully repaired.

You can now reboot your computer.
Please disable SecureBoot in the BIOS.

The boot files of [Ubuntu 16.04.3 LTS] are far from the start of the disk. Your BIOS may not detect them. You may want to retry after creating a /boot partition (EXT4, >200MB, start of the disk). This can be performed via tools such as gParted. Then select this partition via the [Separate /boot partition:] option of [Boot Repair]. (https://help.ubuntu.com/community/BootPartition)

Je ne sais pas quelle peut être la raison mais tu as Secure Boot qui est activé alors qu'il doit être désactivé et en plus, le Boot Mode doit être sur UEFI alors qu'il devrait être sur Legacy :

=================== UEFI/Legacy mode:
BIOS is EFI-compatible, and is setup in EFI-mode for this live-session.
SecureBoot enabled.

Re : Plus de Grub au démarrage (RESOLU)

Bonjour malbo,

j'ai suivi tes conseil et désactivé dans le Bios Secure Boot et je suis passé du mode EFI au mode CSM. J'ai retrouvé le Grub avec toutes les options de démarrage.

Merci encore smile .

Re : Plus de Grub au démarrage (RESOLU)

Aurais-tu une idée sur la raison qui aurait pu faire changer ces paramètres dans le "Bios" ? Est-ce que c'est toi qui avais fait ces modifs dans le Bios et qui avais oublié de remettre tout ça en ordre ou bien est-ce qu'il y aurait eu une mise à jour ou une mise à niveau de Windows qui aurait pu créer sournoisement cette modif du paramétrage du Bios ?

Re : Plus de Grub au démarrage (RESOLU)

Franchement, je ne vois pas ce qui a pu se passer.
Je n'ai pas touché au Bios depuis longtemps. Je n'ai pas fait de mise à jour Windows (je m'en sert très peu et très souvent, je désactive le wifi pour éviter les mises à jour). J'ai bien fait les mises à jour de Kubuntu, mais je ne vois pas comment cela pourrait modifier le Bios.

Une seule chose m'a parut étrange : avant que le problème n'apparaisse, j'avais refermé mon portable et plusieurs heures après, lorsque j'ai voulu m'en servir, il n'a pas pu démarrer faute de batterie. Ce n'est qu'en le branchant que j'ai vu qu'il ne trouvait plus d'OS. Est-ce qu'une perte totale de batterie peut donner ce genre de problème ? J'en doute un peu !

Autre piste que j'ai trouvé en fin du bilan généré par Boot-Repair, il semble que les fichiers de démarrage de Kubuntu soient loin du début du disque, ce qui les rendrait éventuellement non détectables par le Bios. OK, mais avant, ça marchait ! Alors pourquoi ne seraient-ils plus détectés ?

J'ai peur que cela reste un mystère ...

As-tu d'autres hypothèses à vérifier ?

Il est possible que la cause soit proche de ce pb de batterie déchargée (qu'est-ce qui a pu vider la batterie...). Si ça se reproduit, poste ici pour nous informer.
