=================== 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 mapper/mint--vg-root, using the following options: sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le fichier sda1/efi/.../grub*.efi !


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

mkdir: impossible de créer le répertoire «mnt/mint»: Aucun fichier ou dossier de ce type

Pour la 2 eme commande voila le resultat...

Installation en mode EFI de Ubuntu 16.04 64 bits en dual-boot avec Windows 10 préinstallé. Il est indispensable d'utiliser la fonctionnalité "select an uefi file as trusted" dans le "Bios" pour parvenir à démarrer sur Ubuntu.
Va voir dans le bios si tu as cette option.

Oui je l'ai!
