[Résolu] Après installation, impossibilité d'acceder à Ubuntu

Bonjour
j'ai effectué une installation via liveUSB sur un disque propre, l'autre disque conservant windows (10)
après redémarrage, mon ordi ACER Aspire 5 va automatiquement sur windows, à partir duquel je redémarre , via les paramètres, depuis Ubuntu . L'OS est répertorié, le redémarrage s'effectue sans problème, et me voici enfin devant cet écran violet qui me permet de choisir l'OS.
Ubuntu, donc, et tout se passe comme sur des roulettes.
J'éteins l'ordi, et au redémarrage, en lieu du GRUB j'ai un écran noir avec possibilité d'entrer des commandes, je tapes donc /boot
et là en réponse j'ai un truc sur le kernel (pardon, je suis nouveau, et pas bien doué, j'ai pas noté sur le moment)

du coup, /reboot >>et là, retour windows. je relance la liveUSB, et ai fait un boot info, je suis vraiment perdu

boot info
un os-prober me donne ceci

sudo os-prober
/dev/sda1:Ubuntu 18.04.3 LTS (18.04):Ubuntu:linux
/dev/sdb1@/efi/Microsoft/Boot/bootmgfw.efi:Windows Boot Manager:Windows:efi

merci d'avance

(du coup je me demande si je dois utiliser boot repair ou bien s'il y aurait une autre manip à faire)

Re : [Résolu] Après installation, impossibilité d'acceder à Ubuntu

Bonjour,
Tu as noté "mon ordi ACER Aspire 5". C'est imprécis. Je te prie de donner le nom complet de ton modèle d'ordi.

Je colle ci-dessous le contenu du Boot-info dont tu as donné le lien :

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sda1, using the following options:        sdb1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot use-standard-efi-file


=================== Advice in case of suggested repair
Please disable SecureBoot in the BIOS. Then try again.Do you want to continue?


=================== Final advice in case of suggested repair
Please do not forget to make your BIOS boot on sdb1/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.

Re : [Résolu] Après installation, impossibilité d'acceder à Ubuntu

Il y a déjà deux modèles dont le préfixe "A517-51G" correspond à ton modèle dans la Liste des portables « Acer ». Il s'agit du Aspire A517-51G-586N et du Aspire A517-51G-86EX. Dans ces deux cas, l'utilisation de la fonctionnalité "Select an UEFI file as trusted for executing" du "Bios" a permis d'obtenir le démarrage par défaut de l'ordi sur le menu Grub. Tu peux t'appuyer sur la procédure de Gesbuklu pour le faire : https://forum.ubuntu-fr.org/viewtopic.p … #p21468818 EDIT : si tu galères avec la procédure Gesbuklu, tu pourras suivre la procédure plus détaillée de fnx : https://forum.ubuntu-fr.org/viewtopic.p … #p21604079 (c'est la même mais il y a un redémarrage au milieu)

Re : [Résolu] Après installation, impossibilité d'acceder à Ubuntu

merci, y 'aurait-il une commande pour , à partir de la version d'essai de la liveUSB, redémarrer directement du BIOS? parce que sous windows 10, l'accès est compliqué

Tu peux appliquer la "Méthode rapide" expliquée dans cet extrait du tuto du site "Libre à Quimperlé" : https://libreaquimperle.blogspot.com/p/ … ndows.html
Elle précise "Rester appuyer sur la touche "Maj" du clavier et choisir "redémarrer"

Re : [Résolu] Après installation, impossibilité d'acceder à Ubuntu

Alors, bilan.
J'ai bien suivi toute la procédure expliquée par Gesbuklu; sauf que dans l'onglet boot, ubuntu n' apparaissait  toujours pas, donc impossible de changer l'ordre;
déconfit, je redémarre , donc, arrive sous windows, vais dans paramètres>récupération>redémarrer depuis un périphérique (pour relancer la liveUSB ) et là, dans les choix est apparu Ubuntux64 (alors qu'avant, j'avais l'USB, et Ubuntu mais quand je cliquais ubuntu je tombais sur l'écran noir avec ligne de code me demandant le kernel)
je clique sur ubuntux64 et je me retrouve sur mon installation originale.

donc déjà, je suis soulagé. tripoter le BIOS a eu le mérite de faire apparaître cette option.
mais j'aimerais bien savoir s'il est possible d'avoir cet écran violet à chaque démarrage, et ne pas avoir à repasser par windows à chaque fois.

Ce que je comprends de tes explications, c'est que la procédure Gesbuklu n'a pas complètement abouti. Il faut que tu fasses la deuxième partie de la procédure fnx que je t'avais indiquée. Je la colle là cette deuxième partie pour que ce soit plus commode pour toi :
----------------------------------------------------------------------------------
REBOOTER (pour ajouter cette nouvelle entrée dans l'onglet Boot)
Gesbuklu a écrit :

    Il faut retourner dans le menu principal du bios et aller à l'onglet Boot,
    descendre dans le Boot priority order jusqu'à la dernière ligne, où l'on va retrouver le UbuntuShimx64 défini précédemment, le faire remonter de la neuvième place à la première avec la touche F6, et on se retrouve avec l'ordre de boot reconfiguré:
    1. EFI File Boot 0 : UbuntuShimx64
    2. Windows Boot Manager
    3. ...
    F10 pour save and exit et Yes pour confirmer

Re : [Résolu] Après installation, impossibilité d'acceder à Ubuntu

je viens d'effectuer la seconde partie, effectivement Ubuntu est apparu dans la liste du BIOS, j'ai pu le remonter à la première place, et tout a démarré normalement
merci de ta patience, je suis tellement content que ça marche!
un dernier truc, concernant boot info, comment je peux soit le faire marcher, soit désinstaller ses paquets?
c'est optionnel, hein, dans tout les cas encore merci

Re : [Résolu] Après installation, impossibilité d'acceder à Ubuntu

Pour le Boot-info, je te prie d'opérer depuis une session de ton Ubuntu installé et de passer la commande suivante (utilise le copier-coller) :

sudo add-apt-repository -y ppa:yannubuntu/boot-repair

Puis cette commande :

sudo apt update

Et enfin cette dernière :

sudo apt install -y boot-info 

Tu copies le tout (tout ce qu'il y a dans le terminal, les commandes et leur résultat) et tu colles ça dans ta réponse en utilisant les balises (voir ici)

Re : [Résolu] Après installation, impossibilité d'acceder à Ubuntu

Dans le post #13, on peut voir que Boot-info a été parfaitement installé.
A présent, il faut appliquer ce qui est indiqué au paragraphe 1.2 Utilisation de la doc "Créer un rapport Boot-Info". C'est à dire que tu dois passer la commande suivante dans un terminal :

sudo boot-info

Puis tu suivras les indications de ce même paragraphe 1.2 pour noter sur un papier l'URL de ce Boot-info et donner cette URL dans ta réponse.

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sda1, using the following options:        sdb1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot use-standard-efi-file


=================== Advice in case of suggested repair
Veuillez désactiver SecureBoot dans le BIOS. Puis réessayez.Voulez-vous continuer ?


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le fichier sdb1/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.

On y voit cette partie qui montre le paramétrage de ton système UEFI :

=================== efibootmgr -v

Boot2001* EFI USB Device	RC
Boot2002* EFI DVD/CDROM	RC
Boot2003* EFI Network	RC

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

La ligne "BootCurrent: 0003" révèle que le démarrage s'est fait sur l'entrée Boot0003. Cette entrée, tu l'as nommée toi-même "ubuntushix64" lors de l'application de la procédure Gesbuklu, La ligne suivante confirme que la priorité de démarrage se fait bien sur cette entrée :

BootOrder: 0003,0001,0002,2001,2002,2003

Tu as donc parfaitement réussi à mettre en oeuvre la fonctionnalité "Select an UEFI file as trusted for executing" du "Bios"

Je viens d'ajouter une ligne pour ton modèle Aspire A517-51G-3247 dans la Liste des portables « Acer »
Pour mémoire, ce modèle - visible sur cette page de la fnac - est équipé d'un processeur Intel Core i3-7020U et d'une carte graphique dédiée NVIDIA GeForce MX130
