[Résolu] Vérifier / Réparer Grub

Bonjour à tous,

Lors d'une mise à jour automatique le système à mis à jour Grub, puis m'a dis que le disque du Grub n'était pas présent et me proposait de le réinstalle sur le disque de mon choix.
N'ayant qu'un case possible, je n'avais pas de choix.
La cochant celà échouait à chaque fois, et je n'avais d'autre choix que de continuer sans installer Grub.
Du coup j'ai l'immense crainte, qu'au prochain redemarrage, le système ne démarre pas.
Comment pourrais vérifier, réparer le Grub?

Merci

Re : [Résolu] Vérifier / Réparer Grub

Bonjour,
Pour qu'on en sache davantage, je te prie de faire un Boot-Info. Si tu peux faire ce Boot-Info depuis une session de ton Ubuntu installé, c'est préférable. Sinon, tu peux le faire depuis une session live de Ubuntu 16.04 ou Ubuntu 18.04. Tu donneras l'URL de ce Boot-Info dans ta réponse.

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sda1 into the MBR of sda.
Additional repair would be performed: unhide-bootmenu-10s


=================== Advice in case of suggested repair
Vous souhaiterez peut-être ré-essayer après avoir déchiffré vos partitions. (http://doc.ubuntu-fr.org/ecryptfs)
Voulez-vous continuer ?


=================== Final advice in case of suggested repair


Les fichiers de démarrage de [L'OS actuellement utilisé - Ubuntu 14.04.6 LTS] sont loin du début du disque. Votre BIOS pourrait ne pas les détecter. Vous voudrez peut-être re-essayer après avoir créé une partition /boot (EXT4, >200MB, en début de disque). Cela peut être réalisé via des outils tels que gParted. Puis sélectionnez cette partition via l'option [Partition /boot séparée :] de [Boot-Repair]. (http://doc.ubuntu-fr.org/tutoriel/partition_boot)


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

On y voit la mention "veracrypt" et je constate que c'est un logiciel de chiffrement dans cette doc : https://doc.ubuntu-fr.org/veracrypt
Est-ce que tu utilises actuellement le chiffrement pour ton installation de Ubuntu ?

Re : [Résolu] Vérifier / Réparer Grub

Effectivement j'ai un petit contener chiffré via veracrypt, mais toute l'installation n'est pas crypt
Je l'ai relancé sans:

============================= Boot Info Summary: ===============================

 => Grub2 (v2.00) is installed in the MBR of /dev/sda and looks at sector 1 of

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sda1 into the MBR of sda.
Additional repair would be performed: unhide-bootmenu-10s


=================== Final advice in case of suggested repair


Les fichiers de démarrage de [L'OS actuellement utilisé - Ubuntu 14.04.6 LTS] sont loin du début du disque. Votre BIOS pourrait ne pas les détecter. Vous voudrez peut-être re-essayer après avoir créé une partition /boot (EXT4, >200MB, en début de disque). Cela peut être réalisé via des outils tels que gParted. Puis sélectionnez cette partition via l'option [Partition /boot séparée :] de [Boot-Repair]. (http://doc.ubuntu-fr.org/tutoriel/partition_boot)


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

Si j'avais regardé plus attentivement le Boot-Info que j'ai collé dans le post #4, j'aurais vu dans la partie "Mount points" les preuves que tu utilisais bien veracrypt.
A présent que ce point est éclairci, je te prie de passer la commande suivante depuis une session de ton Ubuntu :

sudo debconf-show grub-pc

Tu donneras le retour utilisable de cette commande dans ta réponse.

Re : [Résolu] Vérifier / Réparer Grub

J'ai comparé par rapport à mon Ubuntu 14.04 et chez moi, j'ai :

grub-pc/install_devices_empty: false

(mais moi j'ai une ligne "grub-pc/install_devices:" qui n'est pas vide)
Alors que chez toi, c'est :

grub-pc/install_devices_empty: true

Les autres lignes sont les mêmes que les tiennes.
Je ne sais pas trop quoi te conseiller là. Il faudrait sans doute purger Grub et le réinstaller.

Re : [Résolu] Vérifier / Réparer Grub

Je te remercie et je t'avoue que je suis un peu inquiet du prochain redemarrage.

Ce qui me suprend c'est que os-prober ne me remonte rien
D'un autre coté grub.cfg semble bien avoir les entrés

pour la purge tu parle de :

apt-get install --reinstall grub-pc grub-common

malbo

Re : [Résolu] Vérifier / Réparer Grub

Je ne suis pas certain que cette commande unique soit suffisante. Moi j'aurais purgé avec la commande :

sudo apt-get purge grub-pc grub-common

Puis réinstallé Grub avec :

sudo apt-get install grub-pc
