Grub n'apparaît plus - win10 + xubuntu 20.04 [RÉSOLU]

Salut,

L'écran de démarrage n'apparaît plus, le PC démarre systématiquement sur windows sans laisser le choix de l'OS.
Il s'agit d'une machine (Toshiba Satellite Pro C50-A-1C8) sur laquelle, il y a environ 2 ans, j'avais installé Xubuntu 20.04 à côté de windows 10. Le propriétaire du PC n'a pas réussi à me dire s'il y avait eu quelque chose en particulier (après mise à jour par exemple).

J'ai tenté de réparer le GRUB en lançant Ubuntu via Super Grub et lancer les commandes :

sudo grub-install /dev/sda
sudo update-grub

Mais au redémarrage, pas de GRUB, c'est windows qui prend la main.



J'ai également tenté de réparer avec Boot Repair mais pareil, le démarrage se fait sur windows.

Avant toute manip, j'ai pris la précaution de faire un rapport Boot-Info. Puis j'ai fait un rapport Boot-Info après la réparation Boot Repair.

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would reinstall the grub-efi of
sda5,
using the following options:  sda1/boot/efi
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file

Final advice in case of suggested repair: ______________________________________

Please do not forget to make your UEFI firmware boot on the Ubuntu 20.04.5 LTS entry (sda1/efi/****/grub****.efi (**** will be updated in the final message) file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.
If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\****\grub****.efi (**** will be updated in the final message)

Re : Grub n'apparaît plus - win10 + xubuntu 20.04 [RÉSOLU]

Bonjour lool_lauris,

As-tu essayé ce qui indiqué après boot-repair ?

Please do not forget to make your UEFI firmware boot on the Ubuntu 20.04.5 LTS entry (sda1/efi/ubuntu/grubx64.efi file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.
If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi

Ce qui donne ~ en français

N'oubliez pas de faire démarrer votre firmware UEFI sur l'entrée Ubuntu 20.04.5 LTS (fichier sda1/efi/ubuntu/grubx64.efi) !
Si votre ordinateur redémarre directement dans Windows, essayez de changer l'ordre de démarrage dans votre firmware UEFI.
Si votre firmware UEFI ne permet pas de changer l'ordre de démarrage, changez l'entrée de démarrage par défaut du chargeur de démarrage Windows.
Par exemple, vous pouvez démarrer dans Windows, puis taper la commande suivante dans une invite de commande administrateur :
bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi

Re : Grub n'apparaît plus - win10 + xubuntu 20.04 [RÉSOLU]

Bonsoir.
Windows a certainement fait une mise à jour de sa structure de boot.
tente la réparation de dernière chance

change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi

Ne pas oublier d'être en mode administratif.
La bonne écriture est certainement  devenue.

bcdedit /set '{bootmgr}' path  '\EFI\ubuntu\grubx64.efi'

@ f.x0 :
J'ai bien vu ce message en fin de réparation mais je n'ai pas compris ce qu'il fallait faire... ou plutôt, je ne vois pas où faire cette déclaration !?

EDIT : je parlais de ceci :

La bonne commande est :

bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi

celle avec les ' n'est pas reconnue.

Merci pour vos infos.

Oui oui, c'est OK.
Je n'ai peut-être pas été assez précis dans mon précédent message.
Merci bien, ça fonctionne correctement.

Bonjour,
Pourrais-tu donner le retour complet de la commande : 

efibootmgr -v

Afin qu'on puisse voir ce que ça donne ?

Désolé malbo, le propriétaire du PC a repris sa machine... hmm
Tu penses qu'il peut y avoir un problème résident ? Je ne suis pas sûr de pouvoir récupérer facilement la machine...

Non, pas de problème. Je demandais ça par curiosité.
D'autre part, comme geole l'a signalé plus haut, le problème devait être dû à une mise à jour de Windows. Donc si ça se reproduit que le démarrage par défaut se fasse sur Windows, il faudra refaire la manip avec bcdedit.
