Probleme de boot [resolu]

Bonjour,
j'ai la version ubuntu 18.04 installée sur mon ordinateur. Je dispose de 3 disque dur et hier j'en ai repartitionné et formaté un mais a priori ce n'était pas celui sur lequel le système ubuntu était installé.
Lorsque j'ai redémmaré le système un écran noir s'affiche. J'ai modifié le boot à chaque fois pour orienter sur les 3 disques, résultat 2 écrans noir et pour un autre disque j'ai un message disque non rebootable.
Pouvez-vous m'aider car je n'ai plus accès à l'ordinateur. Je suis en train de tenter de faire un cd de redémarrage sur un autre ordinateur en attendant.
Merci

Re : Probleme de boot [resolu]

Je pense que la démarche est :
- avoir un système bootable (DVD ou clé) pour démarrer une session "Live"
- installer (en live) boot-info
- lancer boot-info pour avoir un diagnostic sur les systèmes installés et les mode de démarrage.

Et préciser ce que tu as fait exactement concernant le repartitionnage et formatage de l'un de tes disques.

Re : Probleme de boot [resolu]

Merci j'ai lancé le boot info avec vos indications.
J'ai une fenêtre détection des systèmes qui s'affiche depuis plus de 15 minutes. Bug?

Re : Probleme de boot [resolu]

La recherche ne semble pas aboutir, la fenêtre détection des systèmes est toujours dans l'état recherche
Que dois-je faire?

Salut,

Peux-tu, depuis un liveCD (ou USB) nous proposer un rapport boot-info ?

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sdc1 into the MBRs of all disks (except live-disks and removable disks without OS).
Additional repair would be performed: unhide-bootmenu-10s


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le disque sdc (ATA SAMSUNG HD103SJ) !

Les fichiers de démarrage de [Ubuntu 18.04.3 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.

Re : Probleme de boot [resolu]

Je pense que la réparation recommandée de Boot-repair va réparer le démarrage d'après ce qu'on peut lire dans cet extrait :

=================== Suggested repair

Additional repair would be performed: unhide-bootmenu-10s

Par contre, il va écrire un chargeur d'amorçage de Ubuntu dans tous les lecteurs (alors que la bonne place serait dans le MBR du disque qui contient Ubuntu c'est à dire le MBR de sdc). Pour éviter cela, il faudrait recourir à l'Utilisation avancée de Boot-repair mais je ne suis pas bien sûr que tu saurais le faire.

Re : Probleme de boot [resolu]

Si tu n'arrives pas à te servir de Boot-Repair, tu peux utiliser Super Grub2 Disk pour parvenir à démarrer sur ton Ubuntu installé. Il est possible de réparer le démarrage de Ubuntu depuis une session de Ubuntu.

Re : Probleme de boot [resolu]

Il faut d'abord télécharger le fichier ISO de Super Grub2 Disk à cette adresse (il s'agit du fichier super_grub2_disk_hybrid_2.04s1.iso) : https://sourceforge.net/projects/superg … o/download
Ensuite, tu graves ce fichier ISO sur un CD ou un DVD avec la fonction "graver une image" d'un logiciel de gravure (tu peux faire ça - le téléchargement et la gravure - sur un autre ordi puisque le tien est en rade).
Tu devras démarrer ton ordi sur ce CD de Super Grub2 Disk puis tu suivras la procédure du paragraphe 3.1 Via le disque SuperGrub de la doc "Comment réinstaller GRUB ?" à partir de la ligne Choisir l'option « Detect any OS » (*). Tu feras la "réinstallation sans purge" proposée dans cette procédure. A noter que pour toi, sdX de la procédure, c'est sdc (le disque dans lequel Ubuntu est installé). La commande d'installation à passer sera la suivante (il faut mettre "sudo" pour être en administrateur) :

sudo grub-install /dev/sdc

La commande de mise à jour de Grub - proposée ensuite dans la procédure - n'est pas nécessaire dans ton cas mais tu peux la passer quand même (en rajoutant sudo également) :

sudo update-grub

(*) Le doc a vieilli : il faut choisir "Detect and show boot methods". Dans le menu avec plein d'entrées qui sera proposé suite à la validation de ce choix, tu essaieras les entrées qui contiennent la mention "5.0.0-29" (le nom du dernier noyau installé de ton Ubuntu) jusqu'à ce que tu trouves l'entrée qui permet de démarrer ton Ubuntu installé.

Re : Probleme de boot [resolu]

Bonjour,
La réparation n'est pas terminée : l'emplacement du chargeur d'amorçage doit être enregistré par Grub comme étant le MBR du disque sdc (au lieu du MBR de sda). Dans ce but, je te prie de passer la commande suivante depuis une session de ton Ubuntu installé :

sudo debconf-show grub-pc

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

Re : Probleme de boot [resolu]

Bonjour,
La ligne intéressante dans ton post #20 est celle-ci :

* grub-pc/install_devices: /dev/disk/by-id/ata-WDC_WD20EFRX-68AX9N0_WD-WMC301208567

Elle indique que Grub a mémorisé que son chargeur d'amorçage est dans le disque WDC_WD20EFRX-68AX9N0_WD-WMC301208567
Si tu fais une recherche de "WDC_WD20EFRX-68AX9N0_WD-WMC301208567" dans le Boot-Info que j'ai collé dans le post #8, tu verras qu'il s'agit de sda. A mon avis, il serait utile de modifier cela. Mais pour éviter de te faire faire une connerie, je te prie de faire un Boot-Info depuis une session de ton Ubuntu installé et de donner l'URL de ce Boot-Info dans ta réponse.

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sdc1 into the MBRs of all disks (except live-disks and removable disks without OS).
Additional repair would be performed: unhide-bootmenu-10s


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le disque sdc (ATA SAMSUNG HD103SJ) !

Les fichiers de démarrage de [L'OS actuellement utilisé - Ubuntu 18.04.3 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 au début du Boot-Info :

=> No boot loader is installed in the MBR of /dev/sda.

C'est ce que je voulais vérifier : que le démarrage ne se faisait pas sur /dev/sda (et par conséquent, qu'il se faisait bien sur /dev/sdc)
A présent, tu peux appliquer la procédure de ce tuto : http://forum.ubuntu-fr.org/viewtopic.php?id=440159
A la 5ème étape du tuto, il faudra que tu remplaces /dev/sda par /dev/sdc

EDIT : en final, quand tu feras la vérification par la commande :

sudo debconf-show grub-pc

Tu devras trouver la ligne intéressante suivante :

* grub-pc/install_devices: /dev/disk/by-id/ata-SAMSUNG_HD103SJ_S246J9JB907917

ce qui prouvera que la modif aura été bien passée puisque SAMSUNG_HD103SJ_S246J9JB907917 est la référence du disque /dev/sdc

Re : Probleme de boot [resolu]

Parfait. Tu ne devrais pas avoir d'ennui consécutif à une future mise à jour de Grub puisque tout est bien calé.
