┌─────────────────────────────────────────────────────────────────────┤ Configuring Secure Boot ├─────────────────────────────────────────────────────────────────────┐

│ Your system has UEFI Secure Boot enabled. │
│ │
│ UEFI Secure Boot requires additional configuration to work with third-party drivers. │
│ │
│ 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 │
│ now needs to be enrolled in your system's firmware. │
│ │
│ 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. │
│ │
│ If you proceed but do not confirm the password upon reboot, Ubuntu will still be able to boot on your system but any hardware that requires third-party drivers to │
│ work correctly may not be usable. │
