HP, Grub, et amorçage bizarre... [RESOLU]

Bonjour à tous,

j'utilise depuis près d'un an un portable en dual boot Ubuntu 18.04 / Windows 10 sur un HP Portable. Les deux systèmes fonctionnent bien. Cependant, lorsque j'avais fais mon partitionnement et la configuration de démarrage, j'ai dû merder quelque part. En effet, par défaut, l'ordi démarre sous Windows. Pour accéder à Ubuntu, je dois appuyer sur "ESC"' au moment du boot. Un message s'affiche "PROCESSUS DE DEMARRAGE EN PAUSE".

Puis, je dois cliquer sur F9, "OPTION DU PERIPHERIQUE d'AMORCAGE"
https://zupimages.net/up/19/06/kbmw.jpg

Ensuite, il me faut descendre sur Ubuntu, dans le "GESTIONNAIRE d'AMORCAGE"
https://zupimages.net/up/19/06/826j.jpg

Enfin j'arrive sur Grub, qui me permet d'appuyer sur ENTREE pour choisir Ubuntu
https://zupimages.net/up/19/06/3b1a.jpg

Vous comprendrez que c'est un peu fastidieux, surtout, que je passe 95% de mon temps sous Linux. J'aimerais réparer cela et démarrer par défaut sous Linux, sans passer par ces intermédiaires, mais J''AI PEUR de tout casser, n'étant pas du tout spécialiste du partitionnement système etc.

J'aimerais bien un peu d'aide. Voilà ce que donne "sudo fdisk -l" :

Re : HP, Grub, et amorçage bizarre... [RESOLU]

Bonjour,
Sur la vue que tu as donnée (ici), on peut voir "Gestionnaire de démarrage du SE". Je te propose d'essayer la technique de winux qu'il a exposée dans ce post : https://forum.ubuntu-fr.org/viewtopic.p … #p21481290
Attention : je pense qu'au préalable il doit falloir activer "Secure Boot" dans le Bios mais je n'en suis pas certain. Si tu as actuellement "Secure Boot" désactivé, je te suggère d'essayer quand même la manip de winux. Si ça merde, tu actives "Secure Boot", tu redémarres l'ordi et tu vas dans le Bios pour vérifier que "Secure Boot" est bien toujours activé et tu fais la manip de winux.

Re : HP, Grub, et amorçage bizarre... [RESOLU]

Merci Malbo ! C'est étrange. Il semble que je sois en Legacy et non en UEFI. J'ai essayé en UEFI, ca démarre direct sur Windows. Dans les 2 cas, le "MODE SECURISE" dans le Bios est grisé ! Je ne peux pas le sélectionner...

Bonjour.

Si tu veux bien poster un boot-info fait depuis ton Ubuntu?. Que l'on puisse voir comment tout ce"ci est installé.

Merci.

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sda7, using the following options:        sda2/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot use-standard-efi-file  restore-efi-backups


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le fichier sda2/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 peut y voir que ton Ubuntu installé démarre en mode EFI (et pas en mode Legacy comme tu le croyais) :

=================== UEFI/Legacy mode:
BIOS is EFI-compatible, and is setup in EFI-mode for this installed-session.
SecureBoot disabled. (maybe sec-boot, Veuillez indiquer ce message à boot.repair@gmail.com)

Re : HP, Grub, et amorçage bizarre... [RESOLU]

Oui j'ai essayé de passer en EFI pour voir si ça changeait quelque chose. Mais je ne peux PAS activer le SECURE BOOT, et, concernant le lien que tu as montré plus haut, je ne vois pas comment "enregistrer" UBUNTU comme choix par défaut dans le gestionnaire de démarrage SE. Tout se passe comme si un secteur de boot était chargé, puis passait la main, sur un autre disque (ou une autre partition), à un autre secteur de boot.

Re : HP, Grub, et amorçage bizarre... [RESOLU]

S'agissant du "Secure Boot", c'est toi-même qui l'a désactivé en juillet 2017 : https://forum.ubuntu-fr.org/viewtopic.p … #p21767882
Si tu ne sais pas le réactiver, moi non plus.

Re : HP, Grub, et amorçage bizarre... [RESOLU]

Bonjour  à tous,
alors je vais peut-être enfin bientôt marquer RESOLU sur ce thread... La semaine passée, mon disque dur a lâché, sans vraiment prévenir, ce qui est relativement discourtois de sa part mais bref...
J'ai acheté un disque (chez Auchan grrr confinement...), créé 4 partitions, installé Windows (pour le montage vidéo et la Pao essentiellement), puis installé Ubuntu 18.04.

=> Il ne trouvait pas le boot car apparamment situé "trop loin" sur le disque. Du coup j'ai rajouté une partition EFI au début du disque, puis réinstallé Ubuntu, et enfin, tout est rentré dans l'ordre.
Après quelques jours à customiser et rajouter mes logiciels, je me rends compte que Grub ne fait pas apparaître Windows ! Bon ce n'est pas un manque si grave pour le moment, mais ça risque d'arriver bientôt. Du coup pour finaliser mon install, j'aimerais savoir comment modifier Grub pour qu'il me lance l'autre système.

Voici ce que me donne sudo fdisk -l :

La partition 2 ne commence pas sur une frontière de cylindre physique.
Les entrées de la table de partitions ne sont pas dans l'ordre du disque.

et ici le Boot-info.

Re : HP, Grub, et amorçage bizarre... [RESOLU]

Salut,

Tu es victime d'une des incohérences des dernières versions d'Ubuntu qui est capable de s'installer en mode efi sur un disque dos. Ca te conduit à l'agréable surprise de faire sauter le drapeau boot de ta partition de démarrage de Windows, et celui-ci ne peut plus démarrer, tant en mode Legacy qu'en mode uefi.

Ça se répare, bien sûr. Mais dans ton cas, comme il reste des traces d'un GRUB Legacy dans le mbr du disque sda, la remise du drapeau boot au bon endroit ne conduira probablement qu'à un "GRUB recue>". J'ai bien un idée d'une procédure de réparation, mais comme elle est fastidieuse, j'attends pour le cas où quelqu'un aurait une idée simple.

Re : HP, Grub, et amorçage bizarre... [RESOLU]

Re,

Première chose à tenter : démarrer ton PC le mode Legacy (et non uefi) pour voir si ton  Linux démarre tout de même. Si oui, nouveau rapport boot-info.

Sinon, démarrer sur le live-cd (ou USB) en mode Legacy et faire également un rapport boot-info.

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sda5 into the MBR of sda.
Grub-efi would not be selected by default because: no-win-efi
Additional repair would be performed: unhide-bootmenu-10s


=================== Final advice in case of suggested repair


Les fichiers de démarrage de [L'OS actuellement utilisé - Ubuntu 18.04.2 LTS] sont loin du début du disque. Votre BIOS pourrait ne pas les détecter. Vous voudrez peut-être réessayer 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.

Quel bordel !
Et cette andouille de Boot-info qui affiche fièrement que la session est démarrée en mode EFI alors qu'elle est démarrée en mode non-EFI c'est sans doute moi l'andouille. Je crois bien que c'est vrai qu'elle est démarrée en mode EFI  :

=================== UEFI/Legacy mode:
BIOS is EFI-compatible, and is setup in EFI-mode for this installed-session.
SecureBoot disabled. (maybe sec-boot, Veuillez indiquer ce message à boot.repair@gmail.com)

Re : HP, Grub, et amorçage bizarre... [RESOLU]

Merci de m'aider les gens !!!

Alors trois petites choses. Je suis retourné dans le BIOS et j'ai activé le mode LEGACY (qui était désactivé). Ce que je trouve bizarre, c'est que les DEUX modes semblent toujours disponibles (?), et je ne vois pas où mettre la préférence sur Legacy. Bref, le PC démarre toujours. J'ai fait un nouveau Boot-info, mais j'ai l'impression qu'ils sont parfaitement identiques...
J'ai voulu rajouter ces lignes manuellement dans /etc/grub.d/40_custom et fait un grub-update : 

menuentry "Windows 8" {
set root=(/dev/sda4,3)
chainloader +1
} 

Du coup, en tapant ESC au démarrage, je trouve l'entrée Windows 8, mais en le choisissant, et ben ca donne peu ou prou ce que prévoyait Ikewdu : rien !

Re : HP, Grub, et amorçage bizarre... [RESOLU]

En effet, tu bootes toujours en uefi. Démarre depuis le liveUSB en legacy (par esc + F9) ; vérifie que c'est bon via la commande :

[ -d /sys/firmware/efi ] && echo "Session EFI" || echo "Session non-EFI"

Et si ça retourne "session non efi", nouveau rapport.

Edit : si tu veux forcer la clé à booter en mode Legacy, tu peux renommer le dossier efi de la clé en toto. Elle ne bootera plus en uefi.

EDIT ; en tapant F9 (options du périphérique d'amorçage), j'arrive apparement sur mon Grub customisé.
grub
Si je choisis Windows 8, je confirme, pas de démarrage possible...

Re : HP, Grub, et amorçage bizarre... [RESOLU]

Encore une fois, vérifie que tu bootes en Legacy. Tu as la commande pour le vérifier. Ton entrée W8 ne peut pas fonctionner pour l'instant. Oublie -la provisoirement...

Ok je viens de démarrer en Live-USB. Le retour de ta commande est bien "session non-EFI". Voici le nouveau rapport.

Re : HP, Grub, et amorçage bizarre... [RESOLU]

Bon,

Avec gparted, tu remets le drapeau boot sur sda4 ( par clic droit sur la partition et "manage flags"). Tu supprimes carrément la partition sda1.et tu valides tout ça. Une fois que c'est fait, tu relances cette fois boot-repair, et tu fais la réparation recommandée.

Normalement, si tout se passe bien, GRUB pour Legacy va être réinstallé il va détecter bootmgr sur sda4 et il ajoutera une entree à GRUB.  Et tu pourras réessayer. Tu auras 2 entrées Windows que tu pourras tester.

Et là, on verra si WS boote ou non... Et sera alors un problème Windows.

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sda5 into the MBR of sda.
Grub-efi would not be selected by default because: no-win-efi
Additional repair would be performed: unhide-bootmenu-10s


=================== Final advice in case of suggested repair


Les fichiers de démarrage de [Ubuntu 18.04.2 LTS] sont loin du début du disque. Votre BIOS pourrait ne pas les détecter. Vous voudrez peut-être réessayer 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.

On peut voir dans cet extrait que la session live n'a pas été démarrée en mode EFI (donc elle a bien été démarrée en mode Legacy) :

=================== UEFI/Legacy mode:
BIOS is EFI-compatible, but it is not setup in EFI-mode for this live-session.
EFI in dmesg.
[    0.000000] ACPI: UEFI 0x000000009CFFD000 000236 (v01 HPQOEM 21B8     00000001 HP   00040000)
SecureBoot maybe enabled.

Vous pouvez maintenant redémarrer votre ordinateur.


Les fichiers de démarrage de [Ubuntu 18.04.2 LTS] sont loin du début du disque. Votre BIOS pourrait ne pas les détecter. Vous voudrez peut-être réessayer 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)
