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.
