[résolu] Dual boot W10 ubuntu mate 18.04 problème EFI

bonjour!

je viens d'installer Ubuntu mate 18.04 en dual boot avec windows 10 sur un dell optiplex 990.

Le problème 'est que j'ai l'impression que ubuntu n'est pas installé en EFI alors que windows oui.

Lors du boot, si je choisi UEFI comme mode de boot dans le bios, il lane diretement windows. Et je n'ai pas reuissi a trouvé ubuntu comme autre boot.

si je met légacy, il boot diretement sur ubuntu mate, mais ans passer par un menu de grub qui me permettrait de choisir mon OS.
Je suposse que j'ai dû me tromper durant l'installation... Faut il que je réinstalle ubuntu?

EDIT: j'ai essayé d'utiliser boot repair depuis ma live usb, mais je ne peux pas booter cette clé en efi (C'est d'ailleurs probablement pour cela que j'ai du faire l'installation en legacy).
j'ai e message qui s'affiche: failed to set moklistRT Out of ressoures

Merci par avance

Re : [résolu] Dual boot W10 ubuntu mate 18.04 problème EFI

bon, j'ai bien essayé de contourner le problème et essayant de voir si je peux me passer du dual boot e utilisat windows sous virtualbox, mais je 'arrive pas a me servir de l'inprimante depuis le système invité.

donc retour a la case départ, il va bien falloir que j'arrive a booter une session live en efi si je veux résoudre mon problème...

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to fix packages) and reinstall the grub-efi-amd64-signed of sda6, using the following options:        sda2/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot use-standard-efi-file


=================== Blockers in case of suggested repair
La session actuelle est en mode Legacy. Veuillez redémarrer l'ordinateur, et utiliser ce logiciel dans une session EFI. Cela vous permettra d'utiliser cette fonctionnalité. Par exemple, utilisez un live-USB de Boot-Repair-Disk-64bit (www.sourceforge.net/p/boot-repair-cd), après avoir vérifié que votre BIOS est réglé pour démarrer l'USB en mode EFI.


=================== Advice in case of suggested repair
Le démarrage de votre ordinateur est en mode Legacy. Vous voudrez peut-être ré-essayer après l'avoir changé en mode EFI.
Voulez-vous continuer ?


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le fichier sda2/efi/.../grub*.efi !

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

Le démarrage de votre ordinateur est en mode Legacy. Vous voudrez peut-être ré-essayer après l'avoir changé en mode EFI.


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

Comme tu le supposais, tu t'es planté pour l'installation. Il fallait installer Ubuntu en mode UEFI parce que Windows était déjà installé dans le mode UEFI : on doit installer tous les OS dans le même mode (voir mon tuto sur le sujet)
On peut voir que ton Ubuntu est installé en mode non-EFI (mode Bios traditionnel) dans cet extrait :

=================== UEFI/Legacy mode:
BIOS is EFI-compatible, but it is not setup in EFI-mode for this installed-session.
SecureBoot disabled.

C'est la mention "is not setup in EFI-mode" qui le précise.

Re : [résolu] Dual boot W10 ubuntu mate 18.04 problème EFI

Tant que tu ne parviendra pas à démarrer en mode UEFI sur ta LiveUSB, tu ne pourras pas avancer. Il y a plein de choses à tenter, y compris refaire ta LiveUSB en utilisant une autre clé USB. Tu peux essayer aussi un autre moyen de réaliser la LiveUSB (moi j'utilise UNetbootin)

Re : [résolu] Dual boot W10 ubuntu mate 18.04 problème EFI

Tu penses qu'il y'a des chances que le problème vienne de la clé ? Je peux essayer de la refaire depuis Ubuntu.
Je peux aussi faire une clé d'une autre distribution. Voir de boot repair...
Je tente et je te tiens au courant, merci !

Re : [résolu] Dual boot W10 ubuntu mate 18.04 problème EFI

Bon, je viens d'essayer de faire une live USB de boot repair, mais la le bios me l'a proposé tout simplement pas en boot UEFI.
Je vais essayer une autre distribution (debian peut être ?)

Re : [résolu] Dual boot W10 ubuntu mate 18.04 problème EFI

Sur Lubuntu, même résultat, si je lance en UEFI j'ai droit au même message.

Pareil en utilisant unetbootin et etcher.

Je dois me rendre à l'évidence, cet ordinateur ne veut pas de Linux en UEFI.
Après plusieurs années sur Ubuntu, je vais devoir repasser à Windows (ma femme en a besoin).

Bon, c'est juste quelques habitudes à changer, je m'e' remettrais !

Merci encore pour votre aide ! wink

Bonjour,
Le message que tu as mentionné dans le post #1 et dans le post #6 est exactement celui-ci (tu as écrit "ressoures" alors que c'est "resources") :

Failed to set MokListRT: Out of Resources

On arrive à trouver des cas sur la toile mais je n'arrive pas à en tirer la moindre piste. Et quand il y a un gus qui a résolu le pb comme ici, ça concerne un modèle particulier et je ne pense pas que ça puisse s'appliquer à ton modèle d'ordi.

Oui, j'ai bien sur cherché de mon côté.

Désolé pour l'erreur, la touche "c" de mon clavier déconne.

Si j'étais vraiment motivé, je réformaterais tout, j'installerai W10 en legacy, puis Ubuntu, mais je dois avouer que la foi me manque...

Ah moins qu'il y'a ait un moyen pour modifier le mode de boot de Windows ?

Merci en tout cas !

Re : [résolu] Dual boot W10 ubuntu mate 18.04 problème EFI

Re!

bien que n'ayant pas compris l'ordinateur refuse de booter une clé en efi, j'ai contourné le problème: j'ai tout simplement tout réinstallé, windows et ubuntu en legacy.
ça ne me pose pas de problème, je ne compte pas mettre de disques durs de plus de 2To.

encore merci!
