(Résolu) Echec reinstallation grub, pblm avec boot repair

pando25 · Le 11/12/2019, à 22:01

Bonjour,

Je suis malheureusement l'une de ces utilisatrices d'un dual boot qui effacent la partition contenant Windows et son boot loader pour faire plus de place à Xubuntu.

J'ai tenté plusieurs moyens de réinstaller le grub :
- un premier, inutile, qui fut d'installer debian pour tout recommencer, suivi de la réinstallation de xubuntu nouvelle version.
- le Boot Repair en mode usb bootable n'a pas été détecté pour démarrer dessus, je ne sais pourquoi.
- le Boot Repair sur une session live de xubuntu produit un message d'erreur qui me renvoie au problème précédent (quand je lance la reparation "Please use this software in a live session, live-cd or live-usb. This will enable this feature")
- la méthode update-grub, puis la méthode chroot :

xubuntu@xubuntu:~$ sudo os-prober
/dev/sdc2:Ubuntu 19.10 (19.10):Ubuntu:linux
xubuntu@xubuntu:~$ sudo update-grub
/usr/sbin/grub-probe: error: failed to get canonical path of `/cow'.
xubuntu@xubuntu:~$ man mkdir
xubuntu@xubuntu:~$ man mount
xubuntu@xubuntu:~$ sudo -s
root@xubuntu:/home/xubuntu# mkdir -p /tmp/newroot
root@xubuntu:/home/xubuntu# mount -t ext4 /dev/sdc2 /tmp/newroot

Voilà, je ne sais quoi changer dans ces méthodes pour que l'installation fonctionne. Mon ordi est un Acer aspire E5-774G de 2016/12/16

Voici le rapport du Boot Info actuel c-a-dire après le chroot.

Merci pour votre temps!

Bonjour,

Oui c'est en fait l'installation d'une autre distribution Trisquel que j'avais essaye apres debian, je pensais qu'il installerait le menu de demarrage en meme temps, mais justement l'installation s'est arretee a ce moment la, donc je ne pensais pas qu'il y etait.

Donc non pas de donnees importantes a conserver.

malbo · Le 12/12/2019, à 12:49

La première phrase de ton post #1 me laisse dans le doute. Est-ce que tu as l'intention de refaire un dual-boot Windows/Xubuntu dans cet ordi ou bien est-ce que tu as renoncé à Windows et que tu souhaites Xubuntu tout seul ?

pando25 · Le 12/12/2019, à 12:53

C'est ça je voudrais Xubuntu tout seul.

malbo · Le 12/12/2019, à 13:50

A mon avis, il faudrait virer tout ce que tu as dans le SSD et le disque dur pour faire une install toute propre. Mais je laisse l'opportunité à un autre aidant de proposer une solution plus conservatrice. Moi je n'ai pas le courage.

pando25 · Le 13/12/2019, à 21:30

Merci malbo, je ne sais pas du tout comment faire ca, mais s'il y a un moyen sans risque de le faire, ca m'intéresse.

Avant j'aimerais essayer de comprendre les résultats de mes tentatives pour installer le grub car je me suis peut-etre trompée dans les formules.
Par exemple, post#1 quand j'ai essayé le chroot pour le sdc2, quand j'écris < /usr/sbin/update-grub >il y a une premiere erreur :

root@xubuntu:/# /usr/sbin/update-grub
Sourcing file `/etc/default/grub'
Sourcing file `/etc/default/grub.d/init-select.cfg'
Generating grub configuration file ...

grub-probe: error: cannot find a GRUB drive for /dev/sdb1.  Check your device.map.
Adding boot menu entry for EFI firmware configuration
done

pourquoi sort-il /sdb1 ? c'est juste l'emplacement de la cle usb qui fait tourner la session live pourtant, est-ce parce qu'il veut utiliser le grub du xubuntu live pour l'installer sur l'ordi ?
dans ce cas, ca coince p-etre parce que le xubuntu 19.10 que j'ai installé apres l'erreur n'a jamais été démarré? (je ne crois qu'a moitié a mes hypotheses car évidemment je debute totalement dans la lecture de ce language..)

Ou bien serait-ce parce que j'aurais du commencer le chroot en écrivant sdc2 au lieu de sdc1, car 'Suggested repair' parle aussi d'utiliser sdc1/boot/efi :

The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sdc2, using the following options:        sdc1/boot/efi,
Additional repai

et aussi la :

=================== Final advice in case of suggested repair
Please do not forget to make your BIOS boot on sdc1/efi/.../grub*.efi file!

Sinon, je vais aussi essayer d'effacer juste la partition cryptée luks comme suggéré dans le boot-info, + retenter de booter avec une cle usb boot repair pour voir si celui-ci accepterait cette fois de m'aider.
Bon je vous tiens au courant de mon cas! >M<

Merci malbo, je ne sais pas du tout comment faire ca, mais s'il y a un moyen sans risque de le faire, ca m'intéresse.

risque de quoi ?

Que les installations de distributions futures ne fonctionnent toujours pas...?
Il est possible de faire le formatage des 2 disques durs simplement avec une live session et le logiciel Disks, écraser toutes les données et que le système d'exploitation linux installé ensuite soit assez complet pour trouver ses marques et installer son grub etc sur la machine ? J'espere ne pas avoir a utiliser un cd de recuperation windows..

Tu as indiqué dans le post #1 que ton ordi est un "E5-774G". Si tu fais une recherche dans la Liste des portables « Acer, tu trouveras 5 modèles dont le nom contient "E5-774G". Par conséquent, je suis certain que Ubuntu ou une de ces variante est bien compatible avec ton modèle d'ordi.

pando25 · Le 14/12/2019, à 15:06

D'accord, j'avais mal compris pourquoi tu disais ne pas avoir le courage! Je pensais que c'etait par rapport aux "risques" de virer tout et faire une install toute propre.
Du coup, si je vire tout et installe xubuntu qui marchait bien, cette fois c'est 100% sur que le grub s'installe correctement ?

malbo · Le 14/12/2019, à 15:08

Je n'avais pas le courage de t'aider à réparer le bordel que tu avais créé dans ton ordi. Par contre, j'ai le courage de t'aider à tout virer et tout réinstaller à neuf.

pando25 · Le 14/12/2019, à 19:03

Super! Merci! Est ce que tu utiliserais cette méthode avec le logiciel disks ? https://lecrabeinfo.net/effacer-complet … linux.html

malbo · Le 14/12/2019, à 21:29

Non. Il suffit d'utiliser Gparted depuis une session live de Xubuntu. Avec Gparted, tu peux créer une nouvelle table de partition GPT (*) sur le disque dur et créer dedans une seule partition (**) au format EXT4 destinée à devenir la partition /home. Toujours avec Gparted, tu peux créer une nouvelle table de partition GPT sur le SSD et tu peux créer dedans :
une partition EFI : voir 2.6 Créer une partition EFI
une partition EXT4 destinée à devenir la partition racine (lui allouer tout l'espace restant sur le SSD)
Quand ce sera fait, tu pourras lancer l'installation de Xubuntu en sélectionnant "Autre chose" à l'étape "Type de partitionnement" et en affectant les partitions préparées d'avance avec Gparted en t'appuyant sur la doc "Installation d'Ubuntu : partitionnement manuel"

(*) voir Création d’une nouvelle table de partitions
(**) voir Création d’une nouvelle partition

Enfin ça démarre ! Trop contente !
Après l'installation, il a fallu encore aller chercher le fichier de boot shimx64.efi dans 'Select an uefi file as trusted for executng', comme expliqué ici.
En tous cas merci Malbo!

Oui, c'est bien ce qu'il fallait faire.
Je te suggère de faire un Boot-info depuis une session de ton Xubuntu fraîchement installé et de donner l'URL de ce Boot-info dans ta réponse. Je pourrai voir si tout est correct.

pando25 · Le 17/12/2019, à 12:19

Yes! voici
je ne sais pas pourquoi il y a toujours un debian qui s'affiche dans la liste, faut-il faire quelque chose comme update-grub? L'ordi met un petit peu plus de temps à démarrer qu'avant (mais tant que ça démarre ça ne me dérange pas!)

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sdb2, using the following options:        sdb1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s    use-standard-efi-file


=================== Final advice in case of suggested repair
N'oubliez pas de rÃ©gler votre BIOS pour qu'il amorce sur le fichier sdb1/efi/.../grub*.efiÂ !


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

Pour moi, l'install est presque parfaite sauf que la ligne suivante :

BootOrder: 0000,2001,0001,2002,2003

révèle que l'entrée 0001 (*) n'est pas en priorité de démarrage. Il faut rectifier cela (tu peux t'appuyer sur la fin de la procédure fnx)

(*) il s'agit de l'entrée que tu as créée en suivant la procédure de Gesbuklu
