Problème de démarage sur Live USB avec SG2D

Bonsoir,

J'ai sauté le pas et ai viré windows de mon portable PB mais peut être un peu trop vite !
Après plusieurs blocages j'ai enfin réussi à lancer Ubuntu via la clé usb + SG2D mais voila :
Sans la clé le PC indique :
NO BOOTABLE DEVICE et se bloque
Avec la clé :
Default boot device mission or boot failed
insert recovery media and hit any key
Then select "boot manager" to choose a new boot device or to boot recovery media
J'arrive enfin au boot manager ou je peut choisir entre :
1 unknown device : (st500lTD12-1DG142)
2 USB HDD USB DISK 2.0

Le choix 2 ne donne rien mais le choix 1 lance ubuntu grace à la clé usb que je peut retirer après le démarage.

Mon secure boot est disabled
le boot mode est UEFI
et le boot priority est :
1 HDD
2 USB

Comment puis- retrouver un démarage normal ?

merci d'avance
Baptiste

Re : Problème de démarage sur Live USB avec SG2D

Peux-tu préciser le nom COMPLET du modèle de ton ordi  Packard Bell ?
Depuis une session de ton Ubuntu installé, je te prie de faire un Boot-Info et de donner l'URL de ce Boot-Info dans ta réponse.

Re : Problème de démarage sur Live USB avec SG2D

Bonjour,
Désolé pour la réponse tardive : coupure internet !
Le modèle du pc est EASYNOTE ENTG71BM
Voici le boot-info : http://paste.ubuntu.com/13308416/
J'ai indiqué ne pas avoir de RAID sans en être sûr.

Merci

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to sign-grub enable-lvm) and reinstall the grub-efi-amd64-signed of mapper/ubuntu--vg-root, using the following options:        sda2/boot, sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s    use-standard-efi-file rename-ms-efi


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le disque sda (500GB) !


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

J'ai du mal à comprendre. S'agit-il d'une installation chiffrée (est-ce que tu dois rentrer une passphrase au démarrage) ?

EDIT : je te prie de passer la commande suivante dans un terminal (c'est un L minuscule au début) :

ls /boot/efi/

Puis celle-ci :

ls /boot/efi/EFI

et enfin cette dernière :

ls /boot/efi/EFI/ubuntu

Motif : ces commandes vont montrer le contenu de ta partition sda1. Celle-ci parait vide dans le rapport Boot-Info mais c'est peut-être un défaut du Boot-Info,

Re : Problème de démarage sur Live USB avec SG2D

Bonsoir,
Non je ne rentre pas de passphrase au démarrage.

Voici le résultat de la commande :
grub.cfg  grubx64.efi  MokManager.efi  shimx64.efi

Re : Problème de démarage sur Live USB avec SG2D

Normalement, en tapotant la touche F12 au démarrage tu dois avoir accès au Boot Menu et la possibilité de sélectionner "ubuntu". Peux-tu confirmer ?

Re : Problème de démarage sur Live USB avec SG2D

Et non !
le boot manager me propose :
1 unknown device : (st500lTD12-1DG142)
2 USB HDD USB DISK 2.0
Le choix 2 ne donne rien mais le choix 1 lance ubuntu grace à la clé usb que je peut retirer après le démarage.

Re : Problème de démarage sur Live USB avec SG2D

SG2D → supergrub ? pourquoi ?
la cle que tu utilises ? qu'est-ce ?
certains ordi sont incapables de booter sur les cles usb comme des disques où serait installé un os-linux , la procedure de boot est differente de celle d'un live usb (un vrai avec syslinux/isolinux)

@J5012 : moi j'ai compris que baptiste22 a réalisé une liveUSB de Super Grub2 Disk suivant la recette que j'indique dans ce post : http://forum.ubuntu-fr.org/viewtopic.ph … #p18288531

Re : Problème de démarage sur Live USB avec SG2D

@baptiste22 : je te suggère de mettre en œuvre la solution de Bougron : http://forum.ubuntu-fr.org/viewtopic.ph … #p17701501
Elle a marché pour un ordinateur de bureau HP Compaq 100-210ef mais il n'y a pas de raison pour que Compaq ne fasse pas la même merde pour un portable : ça devrait marcher aussi pour toi.

supergrubdisk dans cette configuration agit comme chargeur de boot
or j'ai dit que certains ordi sont incapables d'utiliser le chargeur de boot inscrit sur le peripherique usb ...

Mais mon PC démarre grâce à la présence de cette clé usb !... sinon rien !

Re : Problème de démarage sur Live USB avec SG2D

baptiste22,
Peux-tu essayer ce que j'ai proposé dans le post #10 ? S'il y a des choses que tu ne comprends pas dans la procédure à suivre, dis-le et je pourrai t'expliquer.
