message erreur de grub au démarrage

e4c5 · Le 20/01/2021, à 15:32

bonjour,

Ubuntu et w10 sont installés chacun sur leur disque
Tout fonctionnait bien et soudain grub n'arrive plus à démarrer w10

voici le message :

error: file '/EFI/Microsoft/Boot/bootmgfw.efi' not found

J'ai utilisé boot-repair
j'ai le fichier boot-info si nécessaire

Merci pour votre aide

Bonjour,
En effet montrer le Boot-info peut aider. Et surtout indiquer si le Boot-Repair a essayé de réparer.

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would purge (in order to sign-grub) and reinstall the grub-efi-amd64-signed of
sdb1,
using the following options: sdc1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix use-standard-efi-file restore-efi-backups

Final advice in case of suggested repair: ______________________________________

Please do not forget to make your UEFI firmware boot on the Ubuntu 20.04.1 LTS entry (sdc1/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)
