probleme de Grub ( RESOLU )

Bonjour ,

Je suis débutant en Linux et je me suis fait un dualboot win10 sur /dev/sda/ et Ubuntu sur /dev/sdb/.
Tout allait bien et j'ai voulu tester Kubuntu, donc j'ai migrer.
Mais j'avais un problème, l'affichage du bureau changeait toujours en 'bureau' a la place de 'vue de dossier'.
J'ai lu que ça venait du faite que j'ai migrer d'Ubuntu a Kubuntu.
Donc j'ai effacer complètement mon disque dur 'sdb' et réinstaller Kubuntu avec le Grub sur sdb ( je pense ).
Maintenant j'ai plus de Grub qui se lance au démarrage et discover ne fonctionne pas ( a part pour les mises a jour )(bizarre).
Si quelqu’un voudrait bien m'aider (et m'expliquer) car en cherchant les problèmes pour le Grub (J'ai trouvée mais je comprend rien du tout!)

D'avance merci

voici un boot info :

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to fix packages sign-grub enable-lvm) and reinstall the grub-efi-amd64-signed of sdb1, using the following options:        sda1/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 ([url=http://www.sourceforge.net/p/boot-repair-cd]www.sourceforge.net/p/boot-repair-cd[/url]), 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 sda1/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.

Re : probleme de Grub ( RESOLU )

Bonjour
De ce que je vois en premier, Tu évoques un dual boot Windows / OS libre
Ton Windows est installé pour booter avec un  BIOS positionnée sur EFI

sda1: __________________________________________________________________________
    File system:       vfat
    Boot sector type:  FAT32
    Boot sector info:  No errors found in the Boot Parameter Block.
    Operating System:  
    Boot files:        /EFI/Boot/bootx64.efi /EFI/ubuntu/MokManager.efi 
                       /EFI/ubuntu/fwupx64.efi /EFI/ubuntu/grubx64.efi 
                       /EFI/ubuntu/shimx64.efi 
                       /EFI/Microsoft/Boot/bootmgfw.efi 
                       /EFI/Microsoft/Boot/bootmgr.efi 
                       /EFI/Microsoft/Boot/memtest.efi

Ton OS est actuellement positionné en mode NON-EFI.  Tu n'as aucune chance d'avoir un dual boot opérationnel

=================== 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 ?

Mais, j'ai l'impression que tu as installé un OS  version 32 bits et non 64 bits

Re : probleme de Grub ( RESOLU )

Bonjour,
pour le EFI je pensait l'avoir installer en EFI mais j'ai peut-être commis une erreur.
Comment savoir si la clé que j'ai fait est un X32 ou X64 ?

D'avance merci

Re : probleme de Grub ( RESOLU )

J'ai fait uname -a,
et ca me repond : Linux sam-p6-2427eb 4.8.0-42-generic #45~16.04.1-Ubuntu SMP Thu Mar 9 14:10:16 UTC 2017 i686 i686 i686 GNU/Linux.
C'est X64 alors ?

Re : probleme de Grub ( RESOLU )

Bonsoir confirmation de ce que dit Bougron. L'os installé en /dev/sdb1 est un 32 bit

boot-info is executed in installed-session (Ubuntu 16.04.2 LTS, xenial, Ubuntu, i686)

BOOT_IMAGE=/boot/vmlinuz-4.8.0-42-generic root=UUID=6cd829af-be54-4782-8686-3ea66d59497e ro quiet splash vt.handoff=7

Ubuntu, i686 c'est du 32 bit.  i386 aussi pour info.

=============================== sdb1/etc/fstab: ================================

# /etc/fstab: static file system information.

# Use 'blkid' to print the universally unique identifier for a

L'installation est bien faite en Bios_Legacy, pas de partition /boot/efi  FAT32 dans le fstab de /sdb1.

Pour un Ubuntu en 64 bit, il faut prendre une iso  ...-amd64.iso    et non  ...-i668.iso .

Re : probleme de Grub ( RESOLU )

Bonsoir ,
ok et pour installer en mode EFI on fait comment ?
J'ai cru voir que ca a avoir avec la table de partitions .
est-ce que je doit effacer tout mon dd ?
est-ce que c'est normal que j'ai une partition grub dans sda ( linux en sdb )( ca me fait 2 partitions grub? )

Re : probleme de Grub ( RESOLU )

Ton disque dur est ok.   il a déjà booté en EFI.
il faut simplement que tu décides de prendre un OS se terminant par AMD64.ISO et si tu n'as pas modifié le bios, il bootera en EFI.

Bonjour.

Bougron a écrit :

Si çà n'a pas changé. On voit dans le boot info que la machine ne démarre pas en UEFI.

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

Re : probleme de Grub ( RESOLU )

Bonjour,
Kubuntu a été réinstaller en X64.
Le grub fonctionne comme il le faut.

Dernière petite question : discover ne fonctionne toujours pas mais j'ai vu que beaucoup de monde avait le mème problème ( discover fonctionne que pour les mise a jour ).
Je peut le remplacer par synaptic ( ou peut être les utiliser tout les 2? Moi j'aime bien la logithèque de Ubuntu )
