installation ubuntu16.04 double boot de windowsEFI impossible résolu

Le PC est un ACER Aspire E5 30V4
Windows10 64 bits installé en mode UEFI.
Après avoir réduit le disque dur C, j'ai utilisé GParted pour mettre en place les partitions home, systeme Ubuntu et swap pour obtenir:

sda1: Edit system partition fat32 100mib  (inchangé)
sda2: microsoft reservet 16 mib (inchnagé
sda3: basic data partition ntfs 475 giga (était ~950giga) systeme windows
sda4: basic data partition ntfs 1 giga (inchangé: pour restauration systeme windows)
nouveau:
sda6 : ext4 en Home 385 giga
sda7: ext4 en system (ubuntu): 50giga

Puis j'ai installé une 1ere fois Ubuntu par un iso 64bit sur DVD sans désactiver le boot secur du bios EFI.
Rebbot apres fin d'install, ça boot en windows.
Le lancement de boot-repair n'a rien donné.
nb: j'ai eu à un moment donné, cette information:

Go back to the menu and correct this problem
the partition table format in use on your disks normally requires you to create a separatepartition for boot loader code. This partition should be marked for use asan "EFI boot partition" and should be at least 35MB in size. Note that this is not the same as a partition mounted on /boot.
if you do not go back to the partitioning menu and corrct this error, boot laeder installation may fail later, although it may still be possible to install the boot loader a partition.

et comme je ne comprenais pas j'ai relu des discussions puis refait une 2ième installation de ubuntu en partant d'un ubuntu installé sur clé USB et non DVD..

L'installation s'est bien passée. J'ai bien vérifié que j'étais en mode efi pour le lancement d'ubuntu (4 lignes en haut d'écran me demandant ce que je désirais: Essayer ubuntu ou installer.ou ....ou....
Puis j'ai lancé boot-repair en l'installant sur le live USB d'ubuntu.
Résultats:  ça boot directement sur windows.... donc toujours pas de présence ubuntu.
et cette fois j'ai lancé boot info et j'ai les résultats suivants:

Boot successfully repaired.

Please write on a paper the following URL:
http://paste.ubuntu.com/25948390/
In case you still experience boot problem, indicate this URL to:
boot.repair@gmail.com or to your favorite support forum.
You can now reboot your computer.
Please do not forget to make your BIOS boot on sda1/EFI/ubuntu/shimx64.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\ubuntu\shimx64.efi

Le boot serait réparé mais il faudrait que je boote sur sda1/EFI/ubuntu/shimx64.efi  ????

Je ne sais plus ce qu'il faut faire sachant que j'ai reouvert le bios mais que je n'ai toujours que windows manager de proposé..

J'ai bien une piste que je n'ose pas réaliser par peur de détruire l'acces au windows10:
C'est de soit:
1-quand je monte les partitions "/ "et "/home" dans le type d'installation, je devrais également "oser" monter la partition sda1 en "/boot/efi" sans formater... ou
2-il y a une ligne en bas de fenetre du type d'installation qui précise :
"périphérique où sera installer le programme de démarrage" Par defaut il est mis en sda.. Faut-il le modifier pour lui dire sda1.......

Je remarque que la reponse du boot repair

Pouvez-vous me donner votre avis et me guider dans la suite à donner....

merci..

Re : installation ubuntu16.04 double boot de windowsEFI impossible résolu

Bonjour,
Tu dois réinstaller Grub, en utilisant une clé usb ubuntu live, en mode EFI.
Arrivé dans ubuntu live, monte la partition de ton linux. Puis, tape cette commande, en remplaçant le nom d'utilisateur par celui de la session live de ubuntu et le point de montage. Attention, à la fin c'est sda sans chiffre.

sudo grub-install --root-directory=/media/NomUtilisateur/pointMontagePartitionContenantBoot /dev/sda # Sans chiffre à la fin
# exemple : sudo grub-install --root-directory=/media/ubuntu-live/564980254 /dev/sda # sda SANS chiffre
sudo update-grub

C'est facile, la seule difficulté est de récupérer le bon chemin de ta partition monté de ton linux. J'ai pourtant vue plusieurs membre débutants échoué... Prends ton temps

Boot successfully repaired.

You can now reboot your computer.
Please do not forget to make your BIOS boot on sda1/EFI/ubuntu/shimx64.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\ubuntu\shimx64.efi

Tu as écrit dans le post #1 : "Le PC est un ACER Aspire E5 30V4" mais je pense que tu t'es trompé : la désignation exacte de ton modèle est "Acer Aspire E5-774G-30V4" et on peut voir ses caractéristiques sur cette page du site Laptopspirit : http://www.laptopspirit.fr/189772/acer- … 10-go.html
En examinant la Liste des portables « Acer », on peut voir que les quelques modèles dont le nom commence par "Aspire E5-774G" ont tous été installés en utilisant la fonctionnalité "select an uefi file as trusted" dans le "Bios" pour parvenir à démarrer sur Ubuntu. Je te prie donc de faire de même en utilisant la procédure de Gesbuklu : https://forum.ubuntu-fr.org/viewtopic.p … #p21468818

Re : installation ubuntu16.04 double boot de windowsEFI impossible résolu

merci pour vos 2 réponses.
Je vais commencer par réaliser la procédure de Gesbuklu proposée par Malbo (en espérant que je trouverai les bons chemins)
En ce qui concerne la procédure de lukeperp il y a des dénominations que je n'ai pas bien intégré; aussi je traduis:
Quand vous dites  "utiliser une clé usb ubuntu live en mode EFI", je comprends "Mettre le bios en mode EFI et booter le PC (par F2) sur une clé bootable sur laquelle Ubuntu 16.04 64 bits a été installée et lancer la version essayer ubuntu "
Quand vous dites: "Arrivé dans ubuntu live", je comprends, la version try étant installé , "monter la version de ton linux" , je comprends "aller dans le gestionnaire de fichier et cliquer sur "ordinateur"  ou lancer le gestionnaire de disque, et..... (pouvez-vous me confirmer ce qu'il faut faire?) 
En ce qui concerne le nom de l'utilisateur, en version "essai", il n'y a pas de nom d'utilisateur; aussi est-ce le nom donné lors de l'install qui a été faite précédemment?
Et le point de montage le nom de la partition sur laquelle est installé ubuntu: sda7 pour moi.

Je fais les manipulations en fin d'après midi
bonne fin de matinée

Re : installation ubuntu16.04 double boot de windowsEFI impossible résolu

Oui, commence par la procédure de Gesbuklu parce qu'il est très probable que la réinstallation de Grub proposée par LukePerp ne soit pas nécessaire.

Re : installation ubuntu16.04 double boot de windowsEFI impossible résolu

j'essaie d'appliquer mais je bloque:  pas acces au "select an UEFI....."
Par F2 je boote bien sur le bios.
Par contre, le "select an UEFI file as trusted" reste grisé, malgré l'entrée d'un mot de psse (le même) sur SET superviseur passeword, Set user Password et Set HDDO Passeword;
le passeword de boot restant sur Enabeled.
donc je n'ai pas acces au Secure boot mode et les lignes suivantes

Pouvez-vous m'aider?
merci

Re : installation ubuntu16.04 double boot de windowsEFI impossible résolu

Tu n'es pas le premier à avoir un souci de "select an UEFI file as trusted" qui reste grisé. Essaie la méthode Anthagonas (il avait ce même pb) dans ce post : https://forum.ubuntu-fr.org/viewtopic.p … #p21789830
C'est ce passage :

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

Pour l'étape "rebooté", il s'agit simplement de quitter Windows par "Redémarrer"

Inutile de répondre que vous allez faire le plus rapidement possible  l'action qui vous est demandée, vous perdez du temps à répondre, je perds du temps à consulter votre réponse. Pourtant c'est sympathique mais ce n'est pas pratique.

Re : installation ubuntu16.04 double boot de windowsEFI impossible résolu

J'ai pu terminer la procédure de Gesbuklu; il fallait effectivement remettre le secure boot.
et supprimer les mots de pass dans le bios
Cependant lors de la remise en ordre du boot, je m'aperçois:
1: que je n'ai plus "windows boot manager"
Donc j'ai mis en 1:  EFI File Boot 0 : UbuntuShimx64
et en 2: hddO

Mais en bootant: outre un temps long de 2 à 3 mn,
la selection ubuntu /windows n'apparait pas
et le PC relance windows10.   qui heureusement n'est pas perdue.

Comment continuer pour faire apparaitre les 2 systemes d'exploitation avec ubuntu en 1er bien sur?

Nouveauté:
En voulant lancer un boot repair, j'ai fait F12 en redémarrant le PC
et là, apparait la fenêtre BOOT MANAGER
avec sous boot option manager :
1-windows boot manager
2-Ubuntushimx64
Je sélectionne la 2ième ligne et j'ai alors la fenetre de sélection du grub qui s'ouvre et je peux choisir " ubuntu ou windows manager

Donc la solution ne doit pas être bien loin

J'attends votre réponse
Merci

voici le contenu de la commande efibootmgr:

Je m'aperçois qu'il y a maintenant en boot3 Windows manager

Je viens donc de relancer le bios et dans le boot, il apparait maintenant (certainement suite à un redémarrage de windows et de ou de ubuntu via le boot manager (F2).


donc grand merci, tout est remis en ordre et maintenant le démarrage est normal: la mire (grub) apparait de suite et je peux lancer ubuntu ou windows10

Grand merci à vous tous. Je penserai à alimenter la cagnotte...
et je vais mettre la question en résolu.

Re : installation ubuntu16.04 double boot de windowsEFI impossible résolu

Bonjour.
Tu pourrais épurer une entrée via la commande

sudo efibootmgr  -B -b 2

et réordonner via la commande

sudo efi bootmgr -o  1,3
