Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub-efi of
nvme0n1p2,
using the following options: kernel-purge nvme0n1p1/boot/efi
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file restore-efi-backups
Blockers in case of suggested repair: __________________________________________
Please use this software in a live-session (live-CD or live-USB). This will enable this feature.
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the Ubuntu 22.04.3 LTS (boot) entry (nvme0n1p1/efi/****/grub****.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\****\grub****.efi (**** will be updated in the final message)Conseils pour les nouveaux demandeurs et pas qu'eux

Il me semble bien que le grub du disque dur propose aussi de booter windows et le ubuntu du nvme.

Re : problemes de démarrage (résolu)
Merci Geole , le problème est que depuis j'ai essayé de réinstaller Grub avec boot repair avec un livecd et maintenant je ne sais plus démarrer que sur win10 ou je suis actuellement .
Quand j'essaie de démarrer sur ubuntu j'ai une fenêtre noire avec Grub , qui attend apparemment une commande mais laquelle ?

Re : problemes de démarrage (résolu)
Bonsoir.
Tu as du mal commander la réparation.
Cette fois-ci, il faudra faire un boot-info depuis un live-usb. On verra ce qu'il propose en standard.

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub-efi of
nvme0n1p2,
using the following options: kernel-purge nvme0n1p1/boot/efi
Additional repair would be performed: unhide-bootmenu-10s 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 22.04.3 LTS (boot) entry (nvme0n1p1/efi/****/grub****.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\****\grub****.efi (**** will be updated in the final message)Hors ligne

Re : problemes de démarrage (résolu)
Hello Henri56
J'ai eu un problème un peu similaire avec Grub, j'avais résolu mon problème avec ces pages :
https://doc.ubuntu-fr.org/tutoriel/comm … aurer_grub
et
https://lecrabeinfo.net/reparer-restaur … -plus.html
Si ca peux t'aider enfin j'espère !
