[résolu]problème demarrage ubuntu dual boot Windows 10
Bonjour à tous,
J'ai installé récemment, en dual boot sur windows10, UbuntuStudio20.04. Tout marchait bien jusqu'à maintenant, au démarrage j'avais GRUB qui s'affichait pour me demander sur lequel des 2 je voulais booter. Mais, surement suite à une mise à jour Windows, mon ordi démarrage automatiquement sur Win10.
J'ai essayé de changer la priorité de boot dans le BIOS, mais rien y fait il démarre quand même sur Win10. Et quand je le démarre manuellement via le BIOS sur Ubuntu voici le message qu'il m'affiche :
"GNU GRUB version 2.04
Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere esle TAB lists possible device or file completions.
grub> "
voilà je suis relativement débutant sur ubuntu, et là je séche ... Pouvez vous m'aider ?
Merci

Bonjour
Si tu disposes d'un support d'installation de ubuntu, boote avec, installe boot-info et transmets l'URL qui sera générée. https://doc.ubuntu-fr.org/tutoriel/boot-info
Sinon, tu en fabriques un avec windows

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of
sda3,
using the following options: sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix use-standard-efi-file
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the Ubuntu 20.10 entry (sda1/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)Conseils pour les nouveaux demandeurs et pas qu'eux

Re : [résolu]problème demarrage ubuntu dual boot Windows 10
Problème résolu !!!!
J'ai booter mon ordi sur une clé-usb live avec Ubuntu dessus j'y ai installé boot-repair et j'ai lancer la réparation par défault. Le choix de boot est réapparu. Je crois pas avoir vraiment saisi le problème, au moins je saurais quoi faire si ça me refait le coup. En espèrant que je n'ai pas à refaire l'opération à chaque mise à jour de windows...
Merci à vous pour vos réponses aussi rapides qu'efficace, et pour avoir pris le temps de me répondre !!
J'utilise : Ubuntu 20.04 LTS _ Asus S551LN _ Dual Core Intel Core i7-4510U _ NVIDIA Corporation GM108M [GeForce 840M]
