Minimal BASH-line editing is supported

DeMagot

Bonjour,
Suite à l'installation de Windows 10 en dual boot sur mon PC, il m'est devenu impossible de booter sur Ubuntu, je suis dans une console du grub, avec le message en haut "Minimal BASSH-line editing is supported", qui semble me réduire dans les commandes que je peux utiliser.
A partir d'un sujet du forum similaire, je suis tombé sur ce lien : https://doc.ubuntu-fr.org/boot-repair
J'ai suivi la démarche, et on me conseille de partager ce lien afin d'obtenir de l'aide et savoir si je peux utiliser l'option "réparation recommandée" : http://paste.ubuntu.com/p/sTsMVhR3ct/
Je peux démarrer sous Windows sans problème.
PS : contenu du lien ci-dessous :

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sda2, using the following options:        sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot use-standard-efi-file


=================== Final advice in case of suggested repair
Please do not forget to make your BIOS boot on sda1/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.

Merci ! 😃

montre qu'il suffit de réordonner la séquence de boot. Cela se règle dans le bios

Cependant, il suffit que tu bootes avec le support d'installation de ubuntu, que tu choisisses "essayer avant d'installer" et que tu fasses la commande suivante

sudo efibootmgr  -o  0,5

DeMagot

Merci pour cette réponse rapide, j'ai fait la commande, mais ai toujours la même erreur au démarrage, excepté que je n'ai pas à sélectionner Ubuntu au démarrage pour que le pc boot dessus.

Bonjour,
Tu peux faire la "Réparation recommandée" (appelée également "Réparation standard") de Boot-repair.
Tu nous diras ce que ça donne. Sachant que si tu ne t'en sors pas avec ça, il existe aussi Super Grub2 Disk (on t'en dira plus le cas échéant)
