[Résolu] installation sur MSI avec cle usb

Bonjour à toute l'équipe
J'ai fait l'acquisition un MSI GE75 raider RGB 8RE-068XFR en Free Dos.
Intel Core i7-8750H (Hexa-Core 2.2 GHz / 4.1 GHz Turbo - Cache 9 Mo)
NVIDIA GeForce GTX 1060
SSD 256 Go + HDD 1 To

Je ne suis pas un Pro, mais j'avais déjà installé Ubuntu sur d'autres machines et je n'avais pas relevé de difficultés particulières et suivi les instructions du forum...
Mais là ca fait deux jours que je suis dessus, j'ai essayé plein de trucs, j'ai plein de page du forum d'ouverte et je vous avoues que là , bah je sais plus.

J'ai installé Ubuntu via la cle usb crée avec unetbootin, ok
dans le bios , le dd où est ubuntu en tête.
A l'ouverture de ubuntu écran noir ... donc j'ai mis l'option modprobe.blacklist=nouveau
mais je n'arrive pas à l'inscrire dans le Grub ... /cow
j'ai essaye la solution : le chroot... erreur
Pour finir j'ai du faire plus de bêtises qu'autre chose...

Voici le boot info http://paste.ubuntu.com/p/C6rfm9hNkt/

Merci de votre aide

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of nvme0n1p2, using the following options:        nvme0n1p1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s    use-standard-efi-file


=================== Final advice in case of suggested repair
Please do not forget to make your BIOS boot on nvme0n1p1/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.

Au démarrage de l'ordi, presse la touche SHIFT pour faire apparaitre le menu Grub et ajoute le paramètre de noyau modprobe.blacklist=nouveau comme expliqué dans le paragraphe 7.3.1 Modification temporaire de la doc "Le Noyau : cœur du système d'exploitation"
Cette action te permettra de démarrer une session graphique sur ton Ubuntu installé. Depuis cette session graphique, tu installeras le pilote propriétaire pour ta carte graphique en suivant les indications du paragraphe 1. Utilisation en mode graphique

Re : [Résolu] installation sur MSI avec cle usb

Bonjour malbo,
Merci de m'avoir ouvert les yeux...
J'avais déjà fait cette manip mais avec la cle live usb, parceque je n'arrivais pas à lancer le grub avec shift... et la , avec echap ca fonctionne...et oui ! débutant....!!!
Au lancement j'ai eu une fenetre pour la config de secure boot ...
Le lancement d'ubuntu c'est cool ca fonctionne, maintenant le reste....

Je te laisse mon nouveau boot info si jamais tu vois un truc... http:/paste.ubuntu.com/p/VBNWh3wBdF/

Parfois il faudrait prendre plus de recul et poser sur la table.....

MERCI merci

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of nvme0n1p2, using the following options:        nvme0n1p1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s    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 fichier nvme0n1p1/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


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

Cet extrait montre le paramétrage de ton système UEFI :

=================== efibootmgr -v
BootCurrent: 0001
Timeout: 1 seconds
BootOrder: 0001,0006,0004
Boot0001* ubuntu	HD(1,GPT,28964d43-6e0b-4170-a641-96f13015d3c3,0x800,0x100000)/File(EFIUBUNTUSHIMX64.EFI)
Boot0004* Windows Boot Manager	HD(1,GPT,0f85358c-1569-4b08-90c7-ae130a76850d,0x800,0xaf000)/File(EFIMICROSOFTBOOTBOOTMGFW.EFI)..BO
Boot0006* ubuntu	HD(1,GPT,0f85358c-1569-4b08-90c7-ae130a76850d,0x800,0xaf000)/File(EFIUBUNTUSHIMX64.EFI)..BO

=================== UEFI/Legacy mode:
BIOS is EFI-compatible, and is setup in EFI-mode for this installed-session.
No EFI in dmseg.
SecureBoot enabled.

On y voit que le démarrage se fait par défaut sur l'entrée Boot0001 :

Boot0001* ubuntu	HD(1,GPT,28964d43-6e0b-4170-a641-96f13015d3c3,0x800,0x100000)/File(EFIUBUNTUSHIMX64.EFI)

Cette entrée pointe sur la partition 28964d43-6e0b-4170-a641-96f13015d3c3 laquelle est la partition EFI de ton SSD comme on peut voir dans cet autre extrait :

/dev/nvme0n1p1: UUID="F9D5-145E" TYPE="vfat" PARTLABEL="EFI System Partition" PARTUUID="28964d43-6e0b-4170-a641-96f13015d3c3"

On voit une autre entrée nommée également "ubuntu" (Boot0006) qui pointe vers la partition sda1 : je pense que tu as fait une réparation avec Boot-repair qui a créé cette entrée inutile. Ce qui me fait accuser Boot-repair, c'est la présence de "25_custom" dans la partie "/etc/grub.d/" du Boot-info (c'est l'empreinte de la semelle des grosses galoches de Boot-repair)

EDIT : je viens d'ajouter ton modèle GE75 Raider 8RE-068XFR dans la Liste des portables « MSI »
Pour le lecteur qui passe, ce modèle est visible sur cette page du site LDLC : https://www.ldlc.com/fiche/PB00281104.html
Les composants principaux de ce modèle ont été détaillés dans le post #1

Re : [Résolu] installation sur MSI avec cle usb

Merci pour ton interprétation
Effectivement j'ai fait un Boot-repair , on ne peut rien te cacher smile, est ce que c'est gênant cette entrée inutile? si oui comment la supprimer?

Re : [Résolu] installation sur MSI avec cle usb

Tu peux passer la commande suivante :

sudo efibootmgr  -B -b 0006

Pour vérifier que l'entrée est supprimée, passe la commande suivante :

sudo efibootmgr -v

et donne le retour complet de cette commande dans ta réponse.
