[RÉSOLU] Ordinateur Uefi demarre une fois sur deux!!!

Salut ubunteros!
J'ai un Gateway model SX2185 avec uefi. Je me suis fait le plaisir de totalement supprimer Wiwdows 8. Jỳ ai installer Kubuntu 14.04, tout fonctionne à merveille sauf le démarrage. Au premier démarrage l'ordi signal qu'il n'y as de disque pour booter, j’éteins et rallume et à la seconde tentative kubuntu démarre C'est chaque fois la même chose....
Malgré l'installation de boot repair  rien n'a encore changé.
Voici mon boot-info
Merci a tous pour votre aide.

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sda2, using the following options:        sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s


=================== 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 !

Les fichiers de démarrage de [L'OS actuellement utilisé - Ubuntu 14.04.1 LTS] sont loin du début du disque. Votre BIOS pourrait ne pas les détecter. Vous voudrez peut-être re-essayer après avoir créé une partition /boot (EXT4, >200MB, en début de disque). Cela peut être réalisé via des outils tels que gParted. Puis sélectionnez cette partition via l'option [Partition /boot séparée :] de [Réparateur de démarrage]. (http://doc.ubuntu-fr.org/tutoriel/partition_boot)


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

Re : [RÉSOLU] Ordinateur Uefi demarre une fois sur deux!!!

Bonjour,

Peux-tu ouvrir ta partition sda1 via ton gestionnaire de fichiers et copier/coller cette commande dans un terminal :

lsblk

Puis, copie/colle le retour.

malbo

Re : [RÉSOLU] Ordinateur Uefi demarre une fois sur deux!!!

Depuis une session de ton Kubuntu installé, pourrais-tu passer la commande suivante :

sudo efibootmgr -v

puis le commande :

sudo grub-install 

et enfin (pour comparer avec le résultat de la première commande) :

sudo efibootmgr -v

Je te prie de coller tout ce qui s'affiche dans le terminal (colle le pavé complet) dans ta réponse pour qu'on puisse bien voir les commandes passées et leur résultat.

Re : [RÉSOLU] Ordinateur Uefi demarre une fois sur deux!!!

OK, le résultat de la dernière commande indique que le démarrage par défaut de ton ordi devrait se faire sur l'entrée "Boot0002* ubuntu" qui a été créée dans ton système UEFI. Vérifie si tes symptômes au démarrage sont toujours là.

Re : [RÉSOLU] Ordinateur Uefi demarre une fois sur deux!!!

Au démarrage de l'ordi, tu appuies sur la touche E quand tu vois le menu Grub afin d'éditer le choix sélectionné par défaut (l'entrée "ubuntu"),
tu navigues avec les flèches jusqu’à la ligne "gfxmode $linux_gfx_mode" et tu supprimes cette ligne puis tu valides ça par la touche F10. Vérifie si avec cette procédure - lourdingue mais c'est pour investiguer le pb, ce ne sera pas à faire à chaque fois - tu n'as plus la problème d'échec au premier démarrage. Je te propose ça parce que j'ai déjà vu le cas ici : http://forum.ubuntu-fr.org/viewtopic.php?id=1076111

Salut Salut
J'ai bien supprimé la ligne "gfxmode \$linux_gfx_mode". Mais, désolé c'est toujours le même problème...

Re : [RÉSOLU] Ordinateur Uefi demarre une fois sur deux!!!

Salut,

Ca ressemble pas mal au problème de souen ici (à la différence que la chose semble se produire une fois sur 2).
http://forum.ubuntu-fr.org/viewtopic.ph … #p18783141

L'entrée Ubuntu disparaît du démarrage, et WBM est remis en place :

efibootmgr -v
BootCurrent: 0001
Timeout: 1 seconds
BootOrder: 0001,0000

Perso, je penche toujours pour un blocage inhérent au bios ("fast boot" ou autre cochonnerie active ou inactive)... Bizarrement, ces bios semblent chercher leurs entrées de boot ailleurs que dans la partition EFI.

Le test de démarrage avec SGD2 permettrait de confirmer que la situation est similaire.

Re : [RÉSOLU] Ordinateur Uefi demarre une fois sur deux!!!

Pourrais-tu passer la commande :

sudo update-grub 

Puis refaire un Boot-Info depuis ta session de Kubuntu installé et donner l'URL du Boot-Info dans ta réponse.

D'autre part, tu as écrit dans le post #1 : "Au premier démarrage l'ordi signale qu'il n'y as de disque pour booter". Pourrais-tu noter sur un bout de papier le contenu complet du message qui s'affiche et le donner dans ta réponse ?

Re : [RÉSOLU] Ordinateur Uefi demarre une fois sur deux!!!

Salut et merci pour les efforts que vous faites.
Dans le bios j'ai mis launch CSM sous Always. Secure boot et quiet boot sont sur disable.
Au demarrage c'est ecrit;

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sda2, using the following options:        sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s


=================== 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 !

Les fichiers de démarrage de [L'OS actuellement utilisé - Ubuntu 14.04.1 LTS] sont loin du début du disque. Votre BIOS pourrait ne pas les détecter. Vous voudrez peut-être re-essayer après avoir créé une partition /boot (EXT4, >200MB, en début de disque). Cela peut être réalisé via des outils tels que gParted. Puis sélectionnez cette partition via l'option [Partition /boot séparée :] de [Réparateur de démarrage]. (http://doc.ubuntu-fr.org/tutoriel/partition_boot)


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

Re : [RÉSOLU] Ordinateur Uefi demarre une fois sur deux!!!

Dans ce dernier Boot-Info, on peut voir que tu as toujours une entrée pour Ubuntu dans ton UEFI :

efibootmgr -v
BootCurrent: 0001
Timeout: 1 seconds
BootOrder: 0002,0001,0000

Boot0001* UEFI: ST500DM002-1BD142	ACPI(a0341d0,0)PCI(11,0)03120a000000ffff0000HD(1,800,100000,51433955-6c1f-4c1c-98da-b7ba77cd1ea1)..BO

Le démarrage par défaut devrait se faire sur l'entrée "Boot0002* ubuntu" conformément à la ligne "BootOrder: 0002,0001,0000" mais comme le démarrage de ton ordi doit être bridé, ça démarre sur l'entrée "Boot0001* UEFI" comme en atteste la ligne "BootCurrent: 0001", c'est à dire que ça démarre systématiquement sur le fichier /EFI/Boot/bootx64.efi. Moi, je ne sais pas trop ce qu'il y a dans ce fichier bootx64.efi mais tout ce que je sais c'est qu'il parvient à lancer ton Ubuntu.

EDIT : pourrais-tu vérifier que si tu presses la touche F12 au démarrage(*) et que tu la maintiens pressée, tu arrives au "Boot Menu", c'est à dire que tu peux voir un menu qui te propose :

ubuntu
UEFI: ST500DM002
Windows Boot Manager

Si oui, je te prie de sélectionner "ubuntu" et dire si tu parviens bien à démarrer Ubuntu par ce chemin.

(*) j'ai vu dans ce lien que c'était possible d'utiliser cette touche F12 dans ton modèle Gateway SX2185 (même si ce n'est peut-être pas exactement le même modèle que le tien)

Re : [RÉSOLU] Ordinateur Uefi demarre une fois sur deux!!!

Bonjour à tous,

@soujaa: remets CSM à sa valeur initiale sinon tu ne pourras jamais démarrer, CSM=Always démarre le PC en mode BIOS
@malbo: je pense que tu as raison c'est l'entrée Boot0001 qui semble casser la baraque.

Peut-être qu'en la supprimant?
Mais j'ai peur que le PC ne démarre plus du tout.

Une solution serait de convertir l'installation en mode Legacy.

Edit: Ce serait une bonne chose de supprimer les reliquats de Windows dans /boot/efi même si ce n'est pas vraiment le problème

Re : [RÉSOLU] Ordinateur Uefi demarre une fois sur deux!!!

@maxire : merci pour ton intervention, je n'avais pas lu le début du post #12 ("Dans le bios j'ai mis launch CSM sous Always")
@soujaa : le paramètre "launch CSM" étant remis sur "Never" dans le "Bios", peux-tu répondre à ma question dans EDIT du post #13 ?

Re : [RÉSOLU] Ordinateur Uefi demarre une fois sur deux!!!

Bonsoir,
@malbo
Quand j’appuie sur F12 au démarrage il n'y que la ligne UEFI: ST500DM002-1BD142 qui s'affiche. Il n'y a pas UBUNTU ni WINDOWS Boot Manager.
Mais quand je valide UEFI: ST500DM002 alors le grub ubuntu apparait.

malbo

Re : [RÉSOLU] Ordinateur Uefi demarre une fois sur deux!!!

Bonjour,
Depuis une session de ton Ubuntu installé sur disque dur, je te prie de passer les commandes suivantes (valide chaque commande par la touche Entrée. Utilise le copier-coller, ça t'évitera les erreurs de frappe):

md5sum /boot/efi/EFI/Boot/bootx64.efi

md5sum /boot/efi/EFI/ubuntu/grubx64.efi

md5sum /boot/efi/EFI/ubuntu/shimx64.efi

Quand ce sera fait, colle tout ce qui est affiché dans le terminal (les trois commandes et leur résultat) dans ta réponse.

Re : [RÉSOLU] Ordinateur Uefi demarre une fois sur deux!!!

Bonjour,

En plus:

md5sum /boot/efi/EFI/Microsoft/Boot/bootx64.efi

Je pense que cela pourrait être intéressant.
Lorsque tu écris «grub ubuntu apparaît», est-ce le menu, un prompt grub ou un prompt grub-rescue?

donnent la même valeur de clé donc ce sont des fichiers identiques censés lancer le boot manager windows.

C'est le menu grub qui s'affiche lors de la sélection de «UEFI: ST500DM002-1BD142» via le menu F12, je ne comprends pas très bien pourquoi si cette option correspond bien au lancement d'un périphérique censé utiliser bootx64.efi.

Mystère...

Attendons de savoir ce qu'en pense Malbo.

Bonjour,

Supprime ce répertoire "Microsoft" via cette commande :

sudo rm -r /boot/efi/EFI/Microsoft

Puis l'entrée EFI via cette commande :

sudo efibootmgr -b 0000 -B

@soujaa : je ne vois pas du tout l'intérêt des commandes proposées par kalunux pour résoudre ton problème mais comme je ne maîtrise pas le fonctionnement de ton UEFI, il est possible que kalunux ait trouvé l'épine qui est dans ton pied. Passe les commandes qu'il propose, on verra bien.
