[Résolu] Boot d'Ubuntu introuvable

Bonjour, je vais tenter d'expliquer au mieux mon problème.
J'ai un PC portable Acer Aspire VX 15 VX5-591G-5497 avec un SSD (Contenant Windows 10 pré-installé) et un HDD 1To (Sur lequel je tente d'installer Ubuntu en Dual Boot) qui me sert actuellement de stockage.
j'ai donc partitionné mon HDD via gparted sur un Live USB afin de créer les partitions swap et ext4 pour les points de montage / et /home.
Lancement de l'installation d'Ubuntu, ne voulant pas toucher à mon SSD je ne sélectionne pas l'installation automatique mais passe par l'option "autre" , je sélectionne mes points de montage, tout se passe bien, l'installation se termine.

Problème : au redemarrage, l'ordinateur boot sur Win 10.
Le menu Boot Option (F12 au demarrage) ne me propose que le boot windows. J'ai donc désactivé le secure boot, j'ai désactivé le "démarrage rapide" dans windows 10, mais le problème persiste.
Après avoir fait quelques recherches, j'ai lu qu'il était possible que mon boot ubuntu ne soit pas visible s'il était trop loin sur le HDD ( > 200Go je crois) j'ai donc réinstallé Ubuntu en suivant la même méthode, mais en ajoutant un point de montage /boot.
J'ai tenté cette méthode Cependant "select an uefi as trusted for executing " est grisé et inaccessible.
J'ai aussi tenté ceci Mais Ubuntu n'était pas proposé et les autres choix n'ont pas aboutis a un boot.

Voici le boot-info que j'ai obtenu via le Live USB (sdc étant le live USB)

Je n'aime pas vraiment polluer les forums mais je suis dans une impasse.

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sdb2, using the following options:        sdb5/boot, sda1/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
Please do not forget to make your BIOS boot on sdb (1000GB) disk!

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.

Tu as indiqué que le modèle de ton ordi est "Acer Aspire VX 15" mais ce n'est pas correct parce que "Aspire VX 15" désigne une famille de modèle mais pas un modèle particulier. Je te prie de donner le nom complet de ton modèle du genre "Acer Aspire VX5-591G-584Z" comme on peut voir sur cette page : http://www.laptopspirit.fr/185504/promo … -799e.html (je sais que ce n'est pas ton modèle mais c'est un exemple)

Re : [Résolu] Boot d'Ubuntu introuvable

OK
Je te propose de réactiver Secure Boot afin de voir si ça te permet d'utiliser la fonctionnalité "select an uefi file as trusted for executing"

Re : [Résolu] Boot d'Ubuntu introuvable

J'ai donc réactivé secure boot, et suivi cette procédure , après reboot Ubuntu n'apparait pas dans l'onglet Boot, impossible donc de le mettre en tête de liste.

Essaie cette procédure légèrement différente : https://forum.ubuntu-fr.org/viewtopic.p … #p21604079

Re : [Résolu] Boot d'Ubuntu introuvable

Même résultat avec cette procédure

UPDATE :
Ubuntu apparaît désormais dans la liste,
ce que j'ai fait : j'ai re désactivé le secure boot, lancé windows, rebooté, ré-activer le secure boot puis re-commencer la procédure que vous m'avez demandé


Tout fonctionne désormais parfaitement, je marque le sujet comme résolu, un grand merci pour votre aide !!

Re : [Résolu] Boot d'Ubuntu introuvable

Comme souvent, on a du mal à isoler l'action déterminante qui a permis de débloquer le truc. Est-ce que c'est le passage par Windows ("lancé windows, rebooté") qui est est la clé du succès ? Difficile à dire. Cependant, je te remercie d'avoir décrit précisément tes actions.
Je viens d'ajouter ton modèle Aspire VX5-591G-5497 dans la Liste des portables « Acer ». Pour mémoire ce modèle visible sur cette page est équipé d'un processeur Intel Core i5-7300HQ et d'une carte graphique dédiée NVIDIA GeForce GTX 1050
Je te prie de faire un Boot-Info depuis une session de ton Ubuntu installé afin qu'on ait l'état final de ton install. Tu donneras l'URL de ce Boot-Info dans ta réponse.

Re : [Résolu] Boot d'Ubuntu introuvable

Bonjour, désolé du retard, je viens de finir ma journée.

Voici comme convenu mon Boot-info depuis ma session Ubuntu.
Oui ce modèle possède bien l'intel core i5-7300HQ et une carte graphique NVIDIA GeForce GTX 1050 Mobile.

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sdb2, using the following options:        sdb5/boot, sda1/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 régler votre BIOS pour qu'il amorce sur le disque sdb (1000GB) !

Si votre ordinateur redémarre directement sur Windows, essayez de changer l'ordre de démarrage dans votre BIOS.
Si votre BIOS ne permet pas de changer l'ordre de démarrage, changez l'entrée de démarrage par défaut de l'amorceur Windows.
Par exemple, vous pouvez démarrer Windows, puis saisir la commande suivante dans une invite de commande en mode administrateur :
bcdedit /set {bootmgr} path \EFI\...\grub*.efi


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

J'analyse la partie qui m'intéresse le plus, c'est le paramétrage du système UEFI :

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

=================== UEFI/Legacy mode:
BIOS is EFI-compatible, and is setup in EFI-mode for this installed-session.
SecureBoot disabled. (maybe sec-boot, Veuillez indiquer ce message à boot.repair@gmail.com)

On voit que le démarrage se fait par défaut sur l'entrée 0000, laquelle est décrite dans cette ligne :

Boot0000* Ubuntu	PciRoot(0x0)/Pci(0x17,0x0)/Sata(0,0,0)/HD(1,GPT,685d67f9-57f6-4519-826b-b5c7fce54bd0,0x800,0x32000)/File(EFIubuntushimx64.efi)A01 ..

Par identification avec d'autres install, je peux savoir - grâce à la présence de la mention "PciRoot" - que cette entrée est l'entrée que tu as créée avec la fonctionnalité "select an uefi file as trusted for executing" et à laquelle tu as choisi de donner le nom "Ubuntu". Malgré la bagarre que tu as dû faire pour ça, je crois que tu as bien réussi ta mise au point du dual-boot.
Une dernière remarque : il aurait mieux valu installer Ubuntu 16.04.3 64 bits que Ubuntu 17.04 64 bits parce que Ubuntu 16.04.3 64 bits est soutenue jusqu'en Avril 2021 alors que Ubuntu 17.04 ne sera plus soutenue après Janvier 2018 (source). Alors que Ubuntu 16.04.3 64 bits a le même noyau et la même gestion de l'affichage que Ubuntu 17.04 64 bits.
