Problème Grub rescue

Bonjour,

J'ai rencontré un problème suite à l'installation manuelle d'ubunu 18.04

Lors du démarrage de mon pc j'ai ce message qui s'affiche:

error: file '/grub/i386-pc/normal.mod' not found.
Entering rescue mode...
Grub rescue>

Est-ce que vous pourriez me guider pour que je puisse résoudre ce problème SVP? Sachant que je suis novice avec ubuntu.

Merci,

Aurel10

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to enable-raid) and reinstall the grub2 of mapper/ubuntu--mate--vg-root into the MBR of sda, using the following options:     kernel-purge
Additional repair would be performed: unhide-bootmenu-10s


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

manque les fichiers grub.

Boot sur ton support clef/dvd, lors choix essayer/installer t'as l'option pour verifier le support (appelé "disque"). Si t'as un fichier erroné au moins, refais ton support.

Sinon, moi je recommencerais l'installe avec "effacer le disque, etc..." et sans cochez les options lvm et cryptage.

Re : Problème Grub rescue

Merci  pour ton retour lucmars.

En fait, j'aimerais éviter de perdre les données sur mon ordinateur.

Est-ce que l'option "Réparation recommandée" de Boot-Repair est adaptée ou non dans mon cas ?

Si non, que veux-tu dire par "refais ton support" comme je disais dans mon premier message, je suis novice.

Re : Problème Grub rescue

Bonsoir
Tu peux toujours l'essayer. Cela ne mange pas de pain!  Mais évites de dire que ton ordinateur est équipé d'un RAIDS!!!
Y a-t-il un RAID sur cet ordinateur ? yes

Re : Problème Grub rescue

Merci geole pour ton retour.

J'ai la fenêtre "Y-a-t-il un RAIDS sur cet ordinateur?" Dois-je cocher oui ou non?

Je n'ai pas bien saisi l'enjeu de cette manipulation.

Merci de m'éclairer dans ce brouillard épais.

Re : Problème Grub rescue

De mon côté, j'ai fini par avancer un peu et j'ai coché non à la question "Y-a-t-il un RAIDS sur cet ordinateur?"

J'ai demandé un rapport en ligne (url paste bin) et voici l'url que j'obtiens : http://paste.ubuntu.com/p/VDhHSvZbdy/

Merci d'avance pour votre aide.

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to enable-raid) and reinstall the grub2 of mapper/ubuntu--mate--vg-root into the MBR of sda, using the following options:     kernel-purge
Additional repair would be performed: unhide-bootmenu-10s


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

Re : Problème Grub rescue

Bonjour
Je ne sais que te répondre
Tu as bien dit qu'il n'y avait pas de RAIDS
Y a-t-il un RAID sur cet ordinateur ? no

Pourtant la réparation propose toujours

Comme si elle ne prenait pas en compte ta réponse
Est-ce le fait que faire une installation avec du LVM seul sans RAIDS n'est plus admis en version 18.04
boot-info is executed in live-session (Ubuntu 18.04.3 LTS, bionic, Ubuntu, x86_64)

Je te propose de lancer boot-repair et faire la réparation  proposée, Mais si le problème reste identique, il sera plus rapide de  refaire une installation manuelle sur tout le disque  sans cocher l'option LVM  après avoir sauvé tes données de la version 16.04.

Re : Problème Grub rescue

Merci geole, ton aide est vraiment précieuse.

Je viens de lancer le boot-repair et j'arrive à cette fenêtre dont j'ai mis l'url ci-dessous :

Que dois-je faire ?

Pour poster une image sur le forum, il te faut passer par un site web de stockage, genre latoilelibre.

Une fois ton image sur le site, au plus simple tu copies-colles ici son url.

Re : Problème Grub rescue

Tu  valides avec YES le choix de supprimer la structure de boot qui existe.   
     Il est gentil de te dire que cela risque de ne plus booter.   Il me semble que c'est déjà le cas!!!

Après cette suppression il te proposera une série de commandes à exécuter   (par copier/coller)  dans une autre session. Ces commandes devraient réinstaller un grub.

Re : Problème Grub rescue

Bonjour,
Je crois que j'ai trouvé la couille.
Extrait du fichier fstab dans le Boot-Info du post #8 :

# /boot was on /dev/sda1 during installation
UUID=2276edda-e7bb-460f-bc13-d5b9630b7fde /boot           ext2    defaults        0       2

La partition /boot a un identifiant UUID 2276edda-e7bb-460f-bc13-d5b9630b7fde qui n'existe plus dans la machine (on ne le trouve pas dans la partie ""blkid" output" du Boot-Info. Par contre, on y voit cette partition :

/dev/sda1        0cf20ae7-7a54-4b10-82ae-5dcde5738844   ext4       Aurel_1

Mon interprétation : la partition sd1 a été formatée en EXT4 (au lieu de EXT2) pour une raison que j'ignore mais le résultat c'est qu'il n'y a plus de partition /boot

Ma suggestion : sauvegarder sur disque dur externe les données qui se trouvent dans le Ubuntu malade et faire une installation toute neuve en sélectionnant "Effacer le disque et installer Ubuntu" à l'étape "Type d'installation" mais SANS cocher la case "Chiffrer la nouvelle installation de Ubuntu pour la sécurité" et SANS cocher la case "Utiliser LVM pour la nouvelle installation de Ubuntu" (voir capture)

Re : Problème Grub rescue

Merci à tous pour vos contributions.
Grâce à vous j'ai pu réinstaller ubuntu et ma machine est de nouveau fonctionnelle.

A une prochaine.
