[RESOLU] GRUB UEFI- Installation 18.04 en // avec Win10

duo737 · Le 21/10/2018, à 01:48

Bonjour à tous,
je viens d'acheter un desktop ACER Aspire C24-865 avec SSD 256 gB + HD 1TB , windows 10 pré-installé.
Via une clé boot USB j'ai installé en parallèle Ubuntu 18.04 LTS en suivant ce tuto : https://lecrabeinfo.net/installer-ubunt … ws-10.html .
Tout s'est bien déroulé, mais dans le BIOS Setup Utility ( touche Delete), ou dans le boot order UEFI ( touche F12) il n’apparaît aucune option autre que ma clé USB Ubuntu , ou le chargeur de Windows.

Après consultation de ce forum, j'ai installé Boot-info, dont voici le résultat :
http://paste.ubuntu.com/p/CBNqFWxHhy/

J'ai suivi ses recommandations et, après avoir inhibé le mode 'secure boot' , installé et exécuté ensuite boot-repair , qui a tout réparé , dont voici le résultat :
http://paste.ubuntu.com/p/yhXHQdSwGQ/

Malheureusement sans résultat , je peux booter soit sur Win10, soit sur ma clé Ubuntu , mais pas d'autre choix....

Oh puissants experts, pourrais-je bénéficier de vos lumières ?

Grand merci d'avance.

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sdb5, using the following options:        sdb1/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 sdb1/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.

Boot successfully repaired.

You can now reboot your computer.
Please do not forget to make your BIOS boot on sdb1/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

A l'étape 5 du tuto du site lecrabeinfo.net que tu as suivi, il y a un passage intitulé "PC Acer + UEFI". Il faut que tu appliques ce qui est décrit là-dedans. EDIT : si ça ne marche pas avec cette procédure du tuto du site lecrabeinfo.net, je t'indiquerai une autre procédure qu'on propose généralement sur notre forum (en fait, c'est quasiment la même procédure mais expliquée autrement)

Merci pour ta réponse rapide.

Le problème est justement celui-là : l'étape 5 du tuto "PC ACER + UEFI" n'est pas possible , car dans mon BIOS utility il n'y a pas d'options permettant de préciser :
Rendez-vous sur la page Security et sélectionnez : Select an UEFI file as trusted for executing (vous devez activer le Secure Boot pour y accéder).

(J'ai ici 3 photos des pages du Bios Setup , comment les publier par copier/coller )

Pour parvenir à mettre des photos dans ton post, des indications sont données dans Insérer une image (qui renvoie un peu plus bas vers "Balise [lMG] : Image" )

J'avais évoqué dans le post #2 l'existence d'une procédure "maison". Il s'agit de la procédure de Gesbuklu : https://forum.ubuntu-fr.org/viewtopic.p … #p21468818
On y voit une indication importante : "sélectionner le 3è onglet Security, définir un mot de passe pour pouvoir accéder à select an uefi as trusted for executing". Ta 2ème photo montre que tu n'as pas encore défini un mot de passe puisqu'on voit "Supervisor Password Not installed". Il faut donc que tu définisses ce mot de passe de superviseur et quand ce sera fait, tu devrais avoir accès au paramètre "Select an UEFI file as trusted for executing". Si ce n'est pas le cas, pas de désespoir, on a encore d'autres combines à proposer...

Bonjour Malbo,
après avoir créé un mot de passe Superviseur et redémarré le Bios utility , hélas rien n'a changé sur les 3 écrans ci-dessus du post #5.
Une autre suggestion ?
Merci.

malbo · Le 22/10/2018, à 10:38

Essaie la technique de kokotx qu'il a détaillée dans ce post : https://forum.ubuntu-fr.org/viewtopic.p … #p17756581
Cette technique a bien marché pour un ordinateur de bureau Acer Aspire TC-710 qui n'avait pas non plus de fonctionnalité "select an uefi file as trusted" dans son Bios : https://forum.ubuntu-fr.org/viewtopic.php?id=1998266
EDIT : elle a bien marché aussi pour cet ordinateur de bureau ACER Aspire XC-780 : https://forum.ubuntu-fr.org/viewtopic.php?id=2011275

Bonsoir, voici le résultat de la commande recommandée en mode administrateur Win :

PS C:\WINDOWS\system32> bcdedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi
La commande de définition spécifiée n’est pas valide.
Exécutez « bcdedit /? » pour obtenir de l’aide sur la ligne de commande.
Paramètre incorrect.

Et voici ce qu'affiche l'aide sur cette commande :

PS C:\WINDOWS\system32> bcdedit /? TYPES BOOTMGR

GESTIONNAIRE DE DÉMARRAGE

Les types suivants s’appliquent uniquement aux entrées du gestionnaire
de démarrage. Pour plus d’informations sur le format de données de ces
types, exécutez « bcdedit /? FORMATS ».

Démarrage
=========
BOOTSEQUENCE (liste) Définit la séquence de démarrage
unique.
PERSISTBOOTSEQUENCE (booléen) Permet la persistance d’une séquence de
démarrage sur plusieurs démarrages.

DEFAULT (identificateur) Définit l’entrée de démarrage par
défaut.
TIMEOUT (entier) Définit le temps d’attente du
gestionnaire de démarrage en secondes
avant que le gestionnaire de démarrage
sélectionne une entrée par défaut.

Reprise
=======
RESUME (booléen) Indique qu’une opération de reprise
doit être tentée.

RESUMEOBJECT (identificateur) Fournit l’identificateur de l’objet
d’application de reprise.

HIBERBOOT (booléen) Indique qu’une reprise à partir de la veille prolongée doit
être tentée. Utilisé avec le paramètre RESUME
et ne doit pas être modifié.

Affichage
=========
DISPLAYBOOTMENU (booléen) Active l’affichage du menu de
démarrage.
DISPLAYORDER (liste) Définit la liste d’ordre d’affichage
du gestionnaire de démarrage.
TOOLSDISPLAYORDER (liste) Définit la liste d’ordre d’affichage
des outils du gestionnaire de
démarrage.

Pour les types supplémentaires qui s’appliquent au gestionnaire de
démarrage, exécutez « bcdedit /? TYPES BOOTAPP ».

[RESOLU ] La syntaxe de la commande bcdedit de Windows 10 a changé ( voir ce post en anglais : https://superuser.com/questions/979695/ … otmgr-path ) , il suffit tout simplement d'encadrer {bootmgr} entre apostrophes .

Voici la commande Windows et le résultat :

PS C:\WINDOWS\system32> bcdedit /set '{bootmgr}' path \EFI\ubuntu\shimx64.efi
L’opération a réussi.
Encore merci à malbo pour son aide , c'est bien GRUB qui s'affiche au démarrage et permet de choisir Ubuntu ou Win10.

Dernière question , il y a plusieurs entrées Win dans Grub , comment choisir parmi elles ?

malbo · Le 23/10/2018, à 06:00

Bonjour,
Merci pour la rectification de la commande.

Au sujet des entrées Win dans Grub, je te prie de jeter un œil dans le rapport que tu as obtenu à l'issue de la réparation recommandée de Boot-repair que j'ai collé dans le post #2. Dans la partie "sdb5/boot/grub/grub.cfg" de ce rapport, tu trouveras toutes ces entrées indésirables qui se trouvent entre la ligne :

### BEGIN /etc/grub.d/25_custom ###

et la ligne :

### END /etc/grub.d/25_custom ###

Ces lignes indésirables ont été crées par la réparation faite par Boot-Repair qui a créé un script /etc/grub.d/25_custom qui ajoute ces entrées à chaque mise à jour de Grub. Elles sont indésirables parce qu'elles ne sont pas adaptées à ton cas (elles peuvent être utiles pour un autre type de verrouillage du Bios que le tien)
Pour résoudre le problème, il suffit de rendre le script non-exécutable en passant la commande suivante (je l'ai pompée dans ce post de ikewdu) :

sudo chmod -x /etc/grub.d/25_custom

Puis la commande de mise à jour de Grub (afin que ces lignes disparaissent du menu Grub) :

sudo update-grub

Après cela, tu verras au prochain démarrage qu'il n'y aura qu'une seule entrée pour démarrer Windows 10 dans le menu Grub :

Windows Boot Manager (on /dev/sdb1)
