[Résolu] Grub a disparu suite à une simple ouverture du menu boot

Bonjour,
Ce matin, sans raison particulière, je suis allé dans les options de boot de mon ordinateur portable ACER.
Je n'ai rien changé, mais j'ai remarqué que Windows était premier dans la liste des ordres de boot, alors qu'Ubuntu n'y figurait pas.
J'ai quitté le menu, et à ma grande surprise, au lieu de voir apparaître Grub, c'est Windows qui a booté.

Depuis, impossible de booter sur Ubuntu. Windows boot automatiquement et Grub n'apparaît plus.

Ce qui m'étonne vraiment c'est que tout marchait très bien jusque là ! Je n'ai absolument rien changé dans les options de boot.

Suite à ça je suis allé dans le menu de boot, mais il n'y a que Windows de listé, pas de trace d'Ubuntu.

Ne me dites pas qu'il faut que je réinstalle Ubuntu simplement parce que j'ai appuyé sur F2 au démarrage de ma machine ??????

Re : [Résolu] Grub a disparu suite à une simple ouverture du menu boot

Et hier, tu étais sur windows ? Aurait-il fait une mise à jour ?

Bon si t'as toujours ta clef/dvd live, faudra que tu fasses un boot-info pour comprendre.

Effectivement hier Windows a fait une mise à jour, mais ça n'a pas eu l'air d'affecter grub, j'ai pu booté sur ubuntu après.

Pour le boot-info je dois suivre ce tutoriel : https://doc.ubuntu-fr.org/tutoriel/boot-info ?
Et je peux refaire une clé Live, pas besoin de réutiliser celle avec laquelle j'ai installé Ubuntu à la base ?

C'est le bon tuto

Pas nécessaire de refaire une clef, mais c'est comme tu veux

Re : [Résolu] Grub a disparu suite à une simple ouverture du menu boot

Si j'ai bien compris la partie à la fin, il faut que :
- je désactive le secure boot
- je boot sur windows et tape bcdedit /set {bootmgr} path \EFI\...\grub*.efi
- je boot sur live usb et je lance boot-repair
C'est bien ça ?

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sda5, using the following options:        sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot use-standard-efi-file


=================== Advice in case of suggested repair
Please disable SecureBoot in the BIOS. Then try again.Do you want to continue?


=================== Final advice in case of suggested repair
Please do not forget to make your BIOS boot on sda1/efi/.../grub*.efi file!

If your computer reboots directly into Windows, try to change the boot order in your BIOS.
If your BIOS 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


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

Re : [Résolu] Grub a disparu suite à une simple ouverture du menu boot

windows (0003) en premier, puis ton support live (0001) mais quant a ton ubuntu(0002) nul mention.

T'as plusieurs options :

Déjà dans le bios acer avais tu désigné un fichier efi d'ubuntu dans la partie "securité" / "select a trusted efi file" ?

Utiliser la commande efibootmgr pour passer ubuntu en priorité (ça marche ou ça marche pas)

Appliquer boot-repair

Re : [Résolu] Grub a disparu suite à une simple ouverture du menu boot

Merci pour la réponse. Non je n'ai pas désigné de fichier efi dans le bios.
Je vais tenter efibootmgr, mais comme je suis sur Windows pour l'instant, je me demandais s'il fallait que j'en profite pour essayer de rentrer la commande 

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

dans la console admin, j'ai cru comprendre qu'elle permettait de booter automatiquement sur grub ?

Essaies toujours mais dans ton installe ce serait plutot

bcedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi

En fait je suis étonné que ton dual-boot eut fonctionné du premier coup, mais pourquoi pas.

Cela-dit de mémoire, n'aurais-tu pas eu à faire des manips genre bcedit ou utiliser easyuefi, toute chose qu'une màj windows fout en l'air ?

Re : [Résolu] Grub a disparu suite à une simple ouverture du menu boot

Merci beaucoup pour ton aide lucmars, j'ai finalement trouvé la solution.

En fait, comme tu l'avais évoqué, je crois que le problème venait du fait que lors de l'installation d'Ubuntu, je n'ai pas fait la manip suivant : https://forum.ubuntu-fr.org/viewtopic.p … #p21468818 qui permet d'indiquer au bios le fichier EFI à utiliser.

Après avoir fait cette manip me voilà de retour sur Ubuntu. Je ne comprends pas vraiment pourquoi j'ai réussi à dual-boot et à alterner entre Windows et Ubuntu pendant des mois sans problème et que le simple fait d'ouvrir le menu de boot a tout déclenché.... mais bon, c'est réglé !

Tant mieux ! Acer est gentil par ailleurs.
