=================== 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!

@Baroquiste :
Salut,
Ça serait pas plus simple de basculer en mode legacy si son bios le permet ?
Il n'a plus de Windows, il lui suffirait alors de créer une partition bios_boot de 1 Mo en début de disque et il pourrait conserver le format GPT du disque et les avantages qui vont avec ...

J'avais également pensé à cette piste. C'est aussi une bonne option.

Mais dans ce cas, autant passer le disque au format dos, à moins que caillou12 n'envisage de créer une ribambelle de partitions. Les installations Legacy sur gpt avec partition "bios-boot", je trouve ça toujours un peu bancal. Mais il est clair que c'est aussi parfaitement faisable.

Bonjour a tous,
Alors je comprend toujours pas la totalité des mots employés ;)
Alors les histoires de partitions je vais essayer d y répondre. Moi c est un Pc qui me va me servir a pas grand chose de foufou. Bureautique, internet et si possible de temps en temps (pendant le confinement par exemple) faire tourner un jeux (type Football manager, pas quelque chose de trop gros non plus).

J ai bien lu les liens envoyés et les explications de melbo qui ne sont pas tout a fait clair pour moi mais j ai une question, lui il parle d Ubuntu et si j ai bien suivi en dual boot. Moi c est mint (je suppose que le noyau est le même si j ai bien compris) et sans Windows. Faut il que j installé son Ubuntu qui ne présente pas de risque et ensuite que je migre sur mint?

C est ce dont tu parles?

Oui mais hélas ça ne m'aide pas beaucoup...
starting power-off... il ne me dit pas ce qu'il attend.

Et si tu tapes

sudo shutdown now

dans le terminal, est-ce qu'il s'arrête normalement ?

Qu'est-ce que tu as comme carte graphique sur ce pc ?

Sudo shutdown nos, ca me fait pareil. Ça bloqué sur le logo LM.
Je te joins la photo de ce qui est note sur le pc. Il y a noté Intel HD graphics.
Ça suffit comme indication ?
