How To Get Back MOK Management Screen on Dual Boot Install without Disabling Secure Boot

Ubuntu 14

In this article, we will discuss how to get back the MOK (Machine Owner Key) Management screen on a dual boot install without disabling Secure Boot. This is a common issue faced by users who are running a dual boot system with Linux and Windows.

Quick Answer

To get back the MOK Management screen on a dual boot install without disabling Secure Boot, you can switch between the X.Org server driver and the NVIDIA driver in the "Software & Updates" application. This should trigger the appearance of the MOKManager program during the boot process, allowing you to enroll a key without disabling Secure Boot.

What is MOK Management?

MOK Management is a feature provided by Shim, which is a pre-bootloader that Microsoft uses in their Windows systems. Shim allows systems to boot with keys that Microsoft doesn’t directly sign. The MOK Management screen is part of the Shim system and is used to manage these keys.

What is Secure Boot?

Secure Boot is a security standard developed by members of the PC industry to help make sure that your PC boots using only software that is trusted by the PC manufacturer. When the PC starts, the firmware checks the signature of each piece of boot software, including firmware drivers (Option ROMs) and the operating system.

Getting Back the MOK Management Screen

Now let’s dive into the steps to get back the MOK Management screen without disabling Secure Boot.

Step 1: Open the “Software & Updates” Application

The first step is to open the “Software & Updates” application on your Ubuntu system. This can be done by searching for it in the applications menu.

Step 2: Switch to the X.Org Server Driver

Once you have opened the “Software & Updates” application, navigate to the “Additional Drivers” tab. Here, you should see a list of drivers that are available for your system. Find the NVIDIA driver that is currently in use and switch to the X.Org server driver.

The X.Org server driver is an open-source driver that can be used as an alternative to the proprietary NVIDIA driver. Click on “Apply Changes” to save your settings and then restart your computer.

Step 3: Switch Back to the NVIDIA Driver

After your system has restarted, open the “Software & Updates” application again and navigate back to the “Additional Drivers” tab. This time, switch back from the X.Org server driver to the NVIDIA driver.

Click on “Apply Changes” to save your settings and then restart your computer again.

Step 4: Enroll the Key

By switching back and forth between the X.Org server driver and the NVIDIA driver, you should trigger the MOKManager program to appear during the boot process. This will allow you to enroll a key without disabling Secure Boot.
