boot - grub rescue après Windows Update (W10)

choumat

Bonsoir,

J'ai lancé une mise à jour depuis Windows 10, ce qui a corrompu mon GRUB. J'ai réussi à le corriger manuellement via un

set

dans grub rescue.

J'ai changé les deuxième et troisième lignes en incrémentant gptY (de 5 à 6), après avoir trouvé les dossiers (hd1,gpt6)/boot/grub

cmdpath=(hd1,gpt2)/EFI/DEBIAN
prefix=(hd1,gpt6)/boot/grub
root=hd1,gpt6

Puis les commandes

insmod normal

normal

ont fonctionné : j'ai pu lancer mon Ubuntu 18.04 !

Dans le doute, j'ai lancé une réparation recommandée avec boot-repair, mais j'ai à nouveau le même problème au redémarrage ! Heureusement, j'ai noté l'URL de boot-info : http://paste.ubuntu.com/p/VQzkhspSKk/

Est-ce que je relance Ubuntu avec les deux commandes ? Si oui, j'utilise de nouveau boot-repair ?

Merci d'avance pour votre aide !

choumat

edit: Je précise que la MAJ W10 n'est pas finie, j'espère qu'elle ne va pas reproduire le problème encore après.

Le dÃ©marrage de l'ordinateur a Ã©tÃ© correctement rÃ©parÃ©.

Vous pouvez maintenant redÃ©marrer votre ordinateur.
N'oubliez pas de rÃ©gler votre BIOS pour qu'il amorce sur le fichier sda2/EFI/ubuntu/shimx64.efiÂ !

Si votre ordinateur redÃ©marre directement sur Windows, essayez de changer l'ordre de dÃ©marrage dans votre BIOS.
Si votre BIOS ne permet pas de changer l'ordre de dÃ©marrage, changez l'entrÃ©e de dÃ©marrage par dÃ©faut de l'amorceur Windows.
Par exemple, vous pouvez dÃ©marrer Windows, puis saisir la commande suivante dans une invite de commande en mode administrateurÂ :
bcdedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi

choumat a écrit Est-ce que je relance Ubuntu avec les deux commandes ? Si oui, j'utilise de nouveau boot-repair ?

Oui mais n'utilise plus Boot-repair : contente-toi de faire un Boot-info depuis la session Ubuntu et donne l'URL de ce Boot-info dans ta réponse (depuis cette même session Ubuntu)

D'autre part, ce serait utile que tu donnes le nom complet du modèle de ton ordi.

choumat

Bonjour et merci pour votre réponse,

J'ai dû appliquer de nouveau les corrections mentionnées, et voici le boot-info sans boot-repair :
http://paste.ubuntu.com/p/82RCbnYKpY/

Je n'ai pas fait de

sudo update-grub

à la fin, je préfère être sûr de ma manip d'abord.

Le modèle est un MSI GL62 6QF sur lequel j'ai changé le HDD d'origine en un gros SSD. Je ne sais plus s'il était fourni avec W8 ou W10, mais il a une puce OEM pour la license. J'ai juste les deux boots qui sont mentionnés : un W10 et un Ubuntu 18.04. C'est un peu le fouilli mais peut-être que ça vous aidera ?

Bonne journée,

choumat

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sda6, using the following options:        sda2/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot use-standard-efi-file  restore-efi-backups


=================== Final advice in case of suggested repair
N'oubliez pas de rÃ©gler votre BIOS pour qu'il amorce sur le fichier sda2/efi/.../grub*.efiÂ !

Si votre ordinateur redÃ©marre directement sur Windows, essayez de changer l'ordre de dÃ©marrage dans votre BIOS.
Si votre BIOS ne permet pas de changer l'ordre de dÃ©marrage, changez l'entrÃ©e de dÃ©marrage par dÃ©faut de l'amorceur Windows.
Par exemple, vous pouvez dÃ©marrer Windows, puis saisir la commande suivante dans une invite de commande en mode administrateurÂ :
bcdedit /set {bootmgr} path \EFI\...\grub*.efi


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

On fait le point :
Dans le boot-info que j'ai collé dans le post #2, on peut voir qu'au départ l'entrée "debian" est en priorité de démarrage (c'est la ligne BootOrder qui l'indique) :

=================== efibootmgr -v

Après réparation par Boot-repair, la ligne BootOrder montre que l'entrée "ubuntu" a été mise en priorité de démarrage (on le voit dans le post #2) :

efibootmgr -v
BootCurrent: 0001
Timeout: 2 seconds
BootOrder: 0002,0001,0000

Et dans le dernier Boot-info, on a :

=================== efibootmgr -v
BootCurrent: 0001
Timeout: 2 seconds
BootOrder: 0001,0000,0002

C'est à dire que la priorité de démarrage s'est remise sur l'entrée "debian". Pour moi, c'est de la magie. Je ne sais pas quoi te conseiller.

ikewdu

Salut,

Ton PC MSI devrait pouvoir booter depuis un menu de démarrage (touche F11, en principe). Dans la liste proposée par ce menu, l'entrée Ubuntu devrait fonctionner. Si oui, essaie de changer l'ordre de démarrage directement dans le bios.

choumat

Bonsoir à tous les deux,

@malbo, est-ce que ça pourrait être lié à la config que j'ai mise dans mon /etc/default/grub, à savoir que le dernier système est sélectionné par défaut ?

@ikewdu : là, on soulève un autre problème... J'ai eu la bonne idée de mettre un mot de passe de BIOS, et je l'ai bien sûr oublié. :/ Vu le modèle, il n'y a pas de solution immédiate (pas de checksum en cas d'erreur), donc je vais devoir reset depuis la motherboard (bien que certains forums soulignent que ça ne suffit pas). J'ai pas envie de me lancer là-dedans tout de suite, je testerai à la rentrée.

Le problème est donc dû à l'extension de la partition OEM par Windows 10 lors de la mise à jour. Est-ce que vous pensez qu'il y a moyen de résoudre le problème en supprimant cette nouvelle partition ? Je sais que c'est risqué ^^'

Sinon, est-ce que purger GRUB avant de le réinstaller pourrait suffire ? J'ai pas osé non plus aller au bout de cette procédure avec boot-repair.

Merci pour votre aide ! Et joyeux Noël !

choumat

edit: je précise qu'en attendant, j'ai tout de même accès à mon PC via la manip' présentée en post #1 ! Ouf !
Et la MAJ W10 est finie, j'ai supprimé la version de récupération en espérant que Windows allait supprimer la partition OEM, mais non. 🙁

malbo

choumat a écrit @malbo, est-ce que ça pourrait être lié à la config que j'ai mise dans mon /etc/default/grub, à savoir que le dernier système est sélectionné par défaut ?

C'est possible. J'ai vu que ça existe puisqu'on peut voir 2.8 Booter en automatique comme le choix précédent. dans la doc "Tutoriel GRUB 2 : paramétrage manuel". Mais je n'ai jamais pratiqué ce paramétrage.

ikewdu

Re,

Il est assez délicat de te donner le conseil de bricoler ton GRUB dès lors que le bios-uefi est inaccessible. Car si une intervention logicielle n'écrit pas dans la NVram ou la modifie de manière inattendue, les choses peuvent empirer. Perso, je botte en touche dans ces conditions. Bon courage.

geole

choumat a écritBonsoir,
......
J'ai changé les deuxième et troisième lignes en incrémentant gptY (de 5 à 6), après avoir trouvé les dossiers (hd1,gpt6)/boot/grub

cmdpath=(hd1,gpt2)/EFI/DEBIAN
prefix=(hd1,gpt6)/boot/grub
root=hd1,gpt6

Bonjour
Je suis très surpris que tu doives écrire HD1 et pas HD0 comme cela est indiqué dans le boot-info

========================== sda2/EFI/ubuntu/grub.cfg: ===========================
--------------------------------------------------------------------------------

Je te propose de modifier la première ligne du fichier /EFI/ubuntu/grub.cfg pour remplacer hd0 par hd1
On croyait que le bios a détecté un nouveau périphérique que le boot-info ne voit pas.

choumat

Bonjour,

@malbo : OK, je vais essayer de désactiver ça en premier lieu, au cas où ça serait en cause.

@ikewdu : je comprends. Je tenterai de supprimer le MDP du BIOS dès que je rentre de mes vacances, le 02/01/20, et je te tiens au courant !

@geole : Oui, j'ai vu ça aussi, mais c'est bizarre que mon grub rescue le détecte aussi, non ?
Autre chose, le boot-info montre des noms d'OS en minuscules ou CamelCase, mais il n'y a pas d'entrée /EFI/DEBIAN/ comme affichée par la ligne cmdpath donnée par

grub rescue> set
cmdpath=(hd1,gpt2)/EFI/DEBIAN
prefix=(hd1,gpt5)/boot/grub
root=hd1,gpt5

Est-ce que c'est sensible à la casse ? Et à quoi sert cette ligne cmdpath ?

Bonjour
Il est peut-être inutile de garnir cmdpath lors d'un boot en EFI
Les noms de fichiers stockés dans une partition FAT32 sont effectivement insensibles à la casse.

malbo

choumat a écrit grub rescue> set
cmdpath=(hd1,gpt2)/EFI/DEBIAN

Cette ligne correspond à cette entrée extraite de la partie "efibootmgr -v" du Boot-info :

Boot0001* debian	HD(2,GPT,2e025587-7ef2-4c54-91bc-ac91508ba7ad,0xfa000,0x31800)/File(EFIDEBIANGRUBX64.EFI)

le terme 2e025587-7ef2-4c54-91bc-ac91508ba7ad est le PARTUUID (un identifiant unique) de la partition /dev/sda2. La partie finale EFIDEBIANGRUBX64.EFI indique la cible /EFI/debian/grubx64.efi qui se trouve sur cette partition /dev/sda2

malbo

Bonjour,
Il y a une question qui me turlupine : malgré ton "Bios" verrouillé, est-ce que tu parviens à démarrer ton ordi sur une LiveUSB ou un LiveDVD de Ubuntu ?

choumat

Bonjour et bonne année 2020 !

malbo a écritBonjour,
Il y a une question qui me turlupine : malgré ton "Bios" verrouillé, est-ce que tu parviens à démarrer ton ordi sur une LiveUSB ou un LiveDVD de Ubuntu ?

Je dois pouvoir, en ouvrant le laptop et en retirant le SSD.

Pourquoi ? Utiliser la version installée a des conséquences sur le boot-repair ?

choumat

EDIT: j'ai testé ta solution, geole, mais c'était sans effet =( Est-ce qu'après cette modification, je dois faire un grub-update pour mettre à jour le fichier dans /boot/grub/grub.cfg ?

Nuliel

Qu'est ce qu'il se passe si tu te trompes 3 fois de mot de passe? Que te propose t'il? Quel modèle de pc?

choumat

Bonsoir Naziel !

- Après 3 essais, j'ai juste un "Invalid password" statique, sans autre indication (notamment pas de checksum, donc a priori pas de master pwd)
- C'est un laptop MSI GL62 6QF !

Je l'ai ouvert ce matin et j'ai retiré la batterie, mais pas la pile bouton (c'est celle du BIOS, non ?) : j'ai préféré ne pas forcer, car elle est bien attachée. A la place, j'ai appuyé une 15aine de secondes sur un bouton à côté de la pile, en espérant que ça reviendrait au même...

En images (ce n'est pas ma photo, mais ça correspond à ce que j'avais ce matin) : le 1 est la pile bouton, le 2 le bouton.

Apparemment, il reste la possibilité de flasher soit-même une autre version du BIOS via une clé bootable, ou sinon je passerai par le Support MSI.

choumat

Nuliel

Pas la peine d'enlever la pile bios, c'était valable lorsque ce n'était pas des eeprom qui étaient utilisées.
Tu as retesté l'accès au bios après avoir appuyé sur le bouton?

Le reflash c'est casse gueule honnêtement.

choumat

Oui, j'ai testé de nouveau l'accès au bios, mais j'avais encore le champ de saisie du mdp.

Nuliel

As tu suivi ceci: "tu peux tenter d'enlever la batterie et le cordon d'alimentation, laisser la pile bouton, appuyer pendant au moins 10 s sur le bouton"

As tu une inscription JBAT1 pas loin de la puce bios?
Pourrais tu prendre une photo de la zone où se trouve la puce bios sur ton pc?

Quel bios as tu: Insyde H20, Phoenix, ...?
