 │ The system will assist you in configuring UEFI Secure Boot. To permit the use of third-party drivers, a new Machine-Owner Key (MOK) has been generated. This key    │

 │ To ensure that this change is being made by you as an authorized user, and not by an attacker, you must choose a password now and then confirm the change after     │ 
 │ reboot using the same password, in both the "Enroll MOK" and "Change Secure Boot state" menus that will be presented to you when this system reboots.               │

Au reboot de ma machine, on m’a invité à inscrire le MOK

Entrer dedans, consulter la clé puis dites oui pour l’ajouter

Si vous ne le faites pas, le lancement d’une VM ne fonctionnera pas.

Il faudra relancer la commande suivante pour refaire la manip
