UEFI - Disable Secure Boot

From Manjaro Linux
Jump to: navigation, search


Warning: Secure Boot is still only optional for now. Unless users complain, then it is possible that it may become permanent in future.

A particularly nasty "feature" implemented by Microsoft - in collusion with various hardware manufacturers - in the new UEFI system is the Secure Boot option, which is enabled by default. This in essence ensures that your computer will not boot any operating systems that have not been authorised and consequently given permission by Microsoft to be used by you. Competitors must also pay for this permission.

Fortunately, Secure Boot can be disabled to allow you to freely choose which operating system(s) to install and run on your own computer.

Step 1: Access The BIOS Settings

Tip: You do not need to go through the complex and confusing process provided by Windows 8 to access your BIOS or UEFI. You can also click on the images provided below to enlarge them.

The UEFI system sits on top of your computer BIOS. As such, it is necessary to go into the BIOS settings in order to disable the UEFI Secure Boot option in turn. This is achieved by tapping the appropriate Function (F) key - usually <F10> - immediately after turning on or rebooting your system. The <F9> key will usually access the UEFI system itself.


If you accidentally end up in the UEFI menu, then you may see a screen that looks like this.

As illustrated however, it should still be possible to access the BIOS settings from here, on this occasion by pressing the <F10> key.


Upon entering your BIOS settings, then you may see a screen that looks like this.

Step 2: Access The Boot Settings


Once in the BIOS settings, you should be able to use the <left> and <right> arrow keys to navigate the top menu tabs (usually Main, Security, System Configuration and Exit). You can then use the <up> or <down> arrow keys to highlight and select the options provided in these tabs.

1. Navigate using the <left> / <right> arrow keys to the System Configuration tab.

2. The Boot Options section should be now visible. Highlight this by using the <up> / <down> arrow keys.

3. Once highlighted, press <enter> to access it.

Step 3: Disable Secure Boot


Once in the Boot Options, the Secure Boot option should be visible.

1. Highlight the Secure Boot option by using the <up> / <down> arrow keys.

2. Once highlighted, press <enter> to access it.

3. As illustrated, a new menu will pop up, where 'Disabled' or 'Enabled' may be selected. Highlight Disabled by using the <up> / <down> arrow keys, and then press <enter> to confirm.


As illustrated, Secure Boot has now been disabled. Now press the appropriate Function key to Save and Exit. In this instance, the <F10> key must be pressed to do so.


note: You will likely be warned and requested to enter a code displayed on the screen after exiting. There is no need to be intimidated by this.

A confirmation message should appear asking if you want to Exit Saving Changes.

1. Highlight Yes by using the <left> / <right> arrow keys, and then press <enter> to confirm.

2. A black screen should appear, providing a warning and requesting that a code displayed be entered to further confirm your choice. Just type in the code presented and press <enter> to fully complete the process.

Your computer will now begin to boot, and you will be able to install any operating system you want (hint: Manjaro) from now on!
