(resolu)Impossible de démarrer sur Ubuntu
Bonjour,
Après plusieurs désagréments, j'ai du réinstaller ubuntu mate 20.04. J'ai du faire aussi un boot-repair en CD Live mais sans succès.
Le problème vient du Bios UEFI de mon PC. En effet, je modifie l'ordre de démarrage pour avoir Ubuntu en tête pour démarrer sur Grub. Mais cet ordre de démarrage n'est pas mémorisé malgré que je clique sur enregistrer et quitter. Dès que je sors du Bios, l'entrée Ubuntu est remise à sa position avant modification.
Le PC démarre alors sur la première entrée trouvée dans le Bios soit le CD soit Windows. Donc impossible de démarrer Ubuntu
A quoi celà est du ? Que faire ?
Merci de vos conseils.

Re : (resolu)Impossible de démarrer sur Ubuntu
Bonjour,
J'ai installé UBUNTU Mate 20.04.
Au démarrage du PC, si Ubuntu est bien en tête dans le Bios, j'ai un écran noir qui s'affiche avec une ligne "grub>" et du texte en anglais sur le haut qui donne les instructions pour entrer une commande.
Si je tape exit, au bout de quelques secondes, l'écran de boot GRUB s'affiche alors avec le choix du système à charger.
Malgré plusieurs "Boot repair" en session Live avec le CD, cet écran noir apparait toujours.
Si je fais un tour dans le bios au préalable, pas d'écran noir, le menu de boot s'affiche.
A quoi est-ce dû ? Comment supprimer cet écran noir ?
Mon PC est un HP Pavillions 500-365 NF avec bios UEFI et carte graphique Nvidia GeForce GT 705.
Ubuntu est installé avec pilotes NVIDIA.
Cordialement

Re : (resolu)Impossible de démarrer sur Ubuntu
Depuis ton buntu installé fais-nous un boot-info (voir la doc).
Possible que ton disque ait un pète quelque part, on verra cela plus tard.

Re : (resolu)Impossible de démarrer sur Ubuntu
Avec le problème du bios qui ne garde pas en mémoire la séquence de boot.

Avec certain modèle HP c'est parfois le cas.

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would purge (in order to sign-grub) and reinstall the grub-efi-amd64-signed of
sde5,
using the following options: sde3/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file restore-efi-backups
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the L'OS actuellement utilisé - Ubuntu 20.04.1 LTS CurrentSession entry (sde3/efi/****/shim****.efi (**** will be updated in the final message) file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.
If your UEFI firmware 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\****\shim****.efi (**** will be updated in the final message)Gaulois Matter !

Re : (resolu)Impossible de démarrer sur Ubuntu
Le problème est que je suis le mauvais cheval pour ton cas; mais je ne suis pas seul ici.
T'as plus d'un disque, au plus 5 ; rien d'anormal. Par contre niveau grub, sembles que t'ais créé des fichiers custom, est-ce exact ?

Re : (resolu)Impossible de démarrer sur Ubuntu
Salut,
Si tu tapotes F9 au démarrage, peux-tu me dire ce qui s'affiche ? Car, hormis une mauvaise partition efi montée en fstab, je ne vois pas de raison significative pour expliquer ce GRUB inopérant. Trois choses tout de même :
Comme l'installation en mode uefi sur sdc (qui est un disque msdos) est un peu foireuse, peut-être pourrais-tu déjà refaire cette installation proprement.... On verrait peut-être une évolution : disque gpt + uefi.
Idem pour sdb que tu pourrais débrancher, car il contient, selon le rapport, un boot-loader inconnu. C'est peut-être lui qui met le bazar si le PC démarre en Legacy en priorité, et que l'uefi se lance dans un second temps.
Enfin, tu as utilisé un logiciel tiers (grub-customizer ?) qui a laissé des traces de scripts. C'est peut-être lui le responsable.

Re : (resolu)Impossible de démarrer sur Ubuntu
Comment savoir à quel disque physique correspond le sdb ?
Et F9 c'est quand j'allume le PC (comme quand je fais F10 pour accéder au Bios) ?

Si je fais un tour dans le bios au préalable, pas d'écran noir, le menu de boot s'affiche.
Le chargeur d'amorçage qui est utilisé se trouve sur le disque dur interne sda. On peut voir ça dans cet extrait :

Ce chargeur d'amorçage doit rechercher la partition racine de Ubuntu qui se trouve sur le disque dur externe sde.
Quand tu fais un démarrage normal sans faire un tour dans le Bios, le disque dur externe sde n'est pas encore opérationnel, ce qui fait que le chargeur d'amorçage de Grub déclare forfait et que tu obtiens l'écran noir avec une ligne "grub>"
Par contre, en faisant un tour par le Bios, tu laisses le temps au disque externe sde de s'établir.
Cela étant, je n'ai pas de solution à proposer si ce n'est de presser la touche F9 au démarrage quand tu dois démarrer sur Ubuntu : ainsi, ça laisse le temps au disque dur externe de s'établir et tu peux démarrer sur l'entrée "ubuntu" sans problème.

Re : (resolu)Impossible de démarrer sur Ubuntu
C'est donc le disque dur externe sde qui n'est pas assez rapide ?
Quand j'appuie sur F9 au démarrage j'ai un écran qui me demande de confirmer le disque sur lequel demarrer.
Si je démarre sur ubuntu et que je choisis alors Windows dans le menu Grub, je constate lors d'un prochain démarrage que l'ordre est changé dans le bios et que Windows boot manager est alors en premier. Si je ne remodifie pas l'ordre le pc démarre directement sur Windows sans menu Grub. Pourquoi cela ?

Ce n'est pas exact : l'écran demande sur quelle entrée démarrer et non pas sur quel disque démarrer. Toi tu sélectionnes l'entrée "ubuntu" pour démarrer dessus.

Je ne suis pas certain de la réponse donc je préfère m'abstenir.

Salut,
J'avoue que je n'avais pas envisagé cette piste... Si elle se confirme, il ne te restera plus qu'à avoir la partition efi et ton Linux sur le même disque et à placer tout ça en tête au démarrage. C'est déjà le cas pour la première partie, mais comme l'entrée correspondant au grub présent sur sde3 n'apparaît pas dans la listes des éléments bootables, il faudrait l'ajouter. Peut-être que la commande efibootmgr autorisera cet ajout. Sans certitude.
Qu'a donné le débranchement de sdb ?

Re : (resolu)Impossible de démarrer sur Ubuntu
Après réexamen du Boot-info, je pense que la meilleure solution serait d'abandonner l'installation merdique actuelle (sur un disque dur externe) et de faire une installation sur le même disque (sda) que Windows. J'ai vu qu'il y a un taux d'occupation modéré des partitions sda4 (la partition système de Windows) et sda7 (la partition dont le label est "Documents"), ce qui pourrait permettre de réduire la taille de l'une ou l'autre de ces partitions afin de libérer 30 Go pour installer Ubuntu.

Re : (resolu)Impossible de démarrer sur Ubuntu
Bonsoir. Merci malbo, j'ai finalement mis en place ta solution. J'ai installé Ubuntu sur le même disque Windows 10. Tout semble fonctionner, plus d'écran noir Grub mais le menu de boot normal.
J'ai enlevé 2 disques externes dont celui sur lequel était installé Ubuntu auparavant que j'ai formatés.
De plus, le chargement de Ubuntu est plus rapide.
