Boot impossible sur Live CD ou clé USB

Bonjour et merci à ceux qui pourront me répondre,
J'ai un portable Samsung NP300E5A qui fonctionne en dual boot sous Windows 7 et Ubuntu depuis que je l'ai acheté, soit en 2012.
La version d'Ubuntu actuelle est la 14.04. J'ai essayé de faire la mise à niveau vers la 16.04 quand elle est sorti, en utilisant le logiciel qui fait les mises à jour, mais l'ordi ne démarrait pas avec la 16.04. J'ai donc réinstallé la 14.04.
J'aimerais passer à la 18.04 mais, comme je n'ai pas envie de tout planter, j'ai voulu voir ce que ça donnait avec un live CD. J'ai configuré le Bios pour qu'il boote prioritairement sur le CD mais l'ordi ne le voit pas et démarre normalement sur le disque dur. J'ai même supprimé la possibilité de démarrer sur le disque dur, pour être sûr, et là plus du tout de boot. J'ai aussi essayé de booter sur une clé USB avec la version18.04 sans plus de succès.
Quelqu'un aurait-il une idée ?
Merci

Re : Boot impossible sur Live CD ou clé USB

Bonjour,
Démarre une session sur ton Ubuntu 14.04 installé sur disque dur. Connecte ta LiveUSB 18.04 puis fais un Boot-Info depuis cette session de Ubuntu 14.04 et donne l'URL de ce Boot-Info dans ta réponse.
Motif de ma demande :
1) voir l'allure de ton dual-boot actuel
2) voir comment apparaît ta LiveUSB montée (vérifier si elle est bien adaptée pour la future install en cohabitation avec Windows)

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sda6 into the MBRs of all disks (except live-disks and removable disks without OS).
Grub-efi would not be selected by default because: no-win-efi
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot


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

Les fichiers de démarrage de [L'OS actuellement utilisé - Ubuntu 14.04.5 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 [Boot-Repair]. (http://doc.ubuntu-fr.org/tutoriel/partition_boot)


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

Tout parait correcte dans ce Boot-Info, y compris la LiveUSB.
Je te prie de vérifier dans l'onglet Advanced du Bios que le paramètre Fast BIOS Mode est bien sur Disabled (au lieu de Enabled). Sur ce sujet, tu peux voir cette vidéo : https://www.youtube.com/watch?v=JHmZX-Kk_zI

A noter : en principe, pour aller dans le Bios de ton modèle, il faut mettre sous tension et tapoter immédiatement la touche F2

Re : Boot impossible sur Live CD ou clé USB

Bonjour,

Je n'ai pas de Fast Bios Mode dans l'onglet Advanced du Bios. J'ai juste :

CPU Power Saving Mode : enabled
Hyperthreading : enabled
Execute Disable Bit : enabled

Legacy USB Support : enabled
UEFI Boot Support : enabled
AHCI Mode Control : auto
SATA GEN3 Mode : disabled

Battery Life Cycle Extension : disabled
USB S3 wake-up : disabled

Je ne sais pas si ça te dit quelque chose mais en tout cas merci pour ton aide.

Re : Boot impossible sur Live CD ou clé USB

eric01 a écrit :

UEFI Boot Support : enabled

Repasse ce paramètre sur Disabled afin d’empêcher le démarrage en mode UEFI (le mode de démarrage doit rester le mode Bios classique). Il faut valider cette modif en pressant la touche F10 pour sortir du Bios.

Re : Boot impossible sur Live CD ou clé USB

Trouve un ordi assez ancien qui n'est pas équipé du système UEFI (un modèle d'ordi sorti avant 2011 fait l'affaire) et démarre cet ordi sur ta LiveUSB pour faire une session live (essayer sans installer). Si cet ordi n'est pas capable de démarrer dessus en session live, essaie sur un troisième ordi non équipé du système UEFI. Si ça ne veut toujours pas, c'est que ta LiveUSB est nase. A ce moment là, tu prends une autre clé USB pour faire une nouvelle LiveUSB et c'est reparti...
Par contre, si ça marche super avec un autre ordi - non équipé du système UEFI - que ton samsung, je donne ma langue au chat.

Re : Boot impossible sur Live CD ou clé USB

Salut,
Le chat va être content. J'ai trouvé un autre ordi sur lequel la clé marche très bien.  Je pense que je vais essayer avec d'autres distributions linux. Merci pour ton aide en tout cas

Re : Boot impossible sur Live CD ou clé USB

Bonjour.
Peut-être que le boot via ta clé USB commence bien .....
Sans succès est assez vaque.
Ton ordinateur étant assez ancien, il faut certainement que tu utilises un paramètrage  adapté.
je pense à acpi=off  noapic  nomodeset voir chapitre sept de https://doc.ubuntu-fr.org/kernel

Par la suite, je te suggère de faire une installation "à côté de" afin de ne pas éliminer une version qui fonctionne avant d'être certain que la mise à jour 18.04.0 en 18.04.1 s'est bien passée  donc courant août.

Utiliser REFIND au lieu du GRUB https://doc.ubuntu-fr.org/refind . Aidez à vous faire dépanner en suivant le guide et en utilisant les outils de diagnostic J'ai perdu ma gomme. Désolé pour les fautes d'orthographes non corrigées.
