[Résolu] Grub donne son invite de commande et c'est tout

Bonjour,

Après avoir essayé de créer un réseau local, Ubuntu ne démarrait plus.
Je l'ai donc ré-installé : Ubuntu 18.04.3 LTS

Maintenant au lancement, j'obtiens l'invite de commande de Grub :

GRUB >

Mais si avant ça je fais F9, j'ai la sélection du périphérique de démarrage, dans laquelle j'ai la possibilité de choisir une source de démarrage UEFI : ubuntu, que ne démarra pas plus, ou une source de démarrage héritée, soit le CD-ROM, soit le disque dur SATA1, qui lui lance Ubuntu tout-à-fait correctement.

Je comprends avec ça (mais est-ce que je comprends juste ?) que je n'ai pas de partition EFI, mais uniquement "legacy" (je en sais pas bien ce que ça veut dire).

J'ai essayé Boot-Repair, qui ne parvient pas à réparer Grub. J'ai demandé un rapport de boot-info, que voici :

Boot Info Script 8f991e4 + Boot-Repair extra info      [Boot-Info 25oct2017]

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to fix packages) and reinstall the grub-efi-amd64-signed of sda1, using the following options:        sda7/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s    use-standard-efi-file  restore-efi-backups


=================== Blockers in case of suggested repair
La session actuelle est en mode Legacy. Veuillez redémarrer l'ordinateur, et utiliser ce logiciel dans une session EFI. Cela vous permettra d'utiliser cette fonctionnalité. Par exemple, utilisez un live-USB de Boot-Repair-Disk-64bit (www.sourceforge.net/p/boot-repair-cd), après avoir vérifié que votre BIOS est réglé pour démarrer l'USB en mode EFI.


=================== Advice in case of suggested repair
Le démarrage de votre ordinateur est en mode Legacy. Vous voudrez peut-être ré-essayer après l'avoir changé en mode EFI.
Alternativement, vous souhaiterez peut-être ré-essayer après avoir désactivé l'option [Partition /boot/efi séparée :].
Voulez-vous continuer ?


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le fichier sda7/efi/.../grub*.efi !

Le démarrage de votre ordinateur est en mode Legacy. Vous voudrez peut-être ré-essayer après l'avoir changé en mode EFI.


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

Si je comprends juste, sda7 est bien UEFI ?

J'ai déjà essayé de ré-installer Ubuntu, avec le même résultat.

Avez-vous une idée de ce que je pourrais faire ?

Merci et bonne après-midi,
L.

Règles ton bios afin qu'il lance le disque dur en mode legacy et ça devrait le faire.

Gaulois Matter !

Re : [Résolu] Grub donne son invite de commande et c'est tout

Merci lucmars,

J'avais déjà essayé, mais je ne trouve dans aucun des menus du BIOS référence à UEFI ou à legacy. Peux-tu m'en dire plus ?

Merci,
L.

Bonjour
extrait du boot-info

================== Blockers in case of suggested repair
La session actuelle est en mode Legacy....... 

avant que la ligne contenant le mot grub? s'affiche, n'aurait-tu pas d'autres lignes plus explicatives?

Re : [Résolu] Grub donne son invite de commande et c'est tout

Oui, parfois il y a deux ou trois lignes qui s'affichent mais ça ne dure que moins d'une seconde, impossible de les lire.
Est-ce que ça serait écrit dans un journal quelque part ?

Re : [Résolu] Grub donne son invite de commande et c'est tout

Lorsque l'invite de commande GRUB est affichée, il y a en haut de page :

            GNU GRUB version 2.04
Minimal BASH-like line editing is supported.

puis quelques indications sur la complétion automatique des commandes.
Je ne pense pas que ce soit de ça dont tu veux parler.

Les lignes dont je parlais dans mon message précédent s'affichent avant ça, puis s'effacent à peu près immédiatemment.

Re : [Résolu] Grub donne son invite de commande et c'est tout

Cela pourrait être avant ces quelques lignes

avec une seule ligne   disant qu'il manque une partition intitulée
search.fs_uuid 29643a4f-445b-491c-b239-b26364067dc2 root hd0,msdos1

Je crois avoir vu mi-janvier que ton ordinateur était assez particulier.
Peut-être devrais-tu booter en EFI et faire la réparation recommandée et la poster surtout si elle ne fonctionne pas.

Re : [Résolu] Grub donne son invite de commande et c'est tout

@ geole : le problème, c'est que je ne sais pas démarrer en EFI

@ xubu1957 : je vais essayer de reprendre les messages de janvier pour voir comment je m'en étais tiré. Je vous tiens au courant.

Merci et bonne soirée,

Re : [Résolu] Grub donne son invite de commande et c'est tout

Re - bonsoir,

Comme en janvier, j'ai supprimé la partition sda7 et ÇA MARCHE !
Mais je ne comprends pas pourquoi.

Enfin, si ça fonctionne, c'est l'essentiel

Alors, merci à tous les trois de votre aide précieuse.

Bonne soirée à tous,
L.
