How to Turn on Secure Boot Windows 11: A Step-by-Step Guide

Turning on Secure Boot in Windows 11 is a simple process that can greatly enhance the security of your computer. Secure Boot is a feature that helps prevent malicious software from loading during the system startup process. By enabling Secure Boot, you can ensure that only trusted software with the correct digital signature is allowed to run on your system.

Step by Step Tutorial: Enabling Secure Boot on Windows 11

Before we dive into the steps, it’s important to understand that enabling Secure Boot will ensure that your system boots using only software that is trusted by the motherboard manufacturer. This is a security measure designed to protect your system from malware and other unauthorized software.

Step 1: Enter the BIOS or UEFI Settings

The first step is to enter the BIOS or UEFI settings on your computer.

To do this, you will need to restart your computer and press a specific key during the startup process. This key is usually one of the function keys (F1, F2, F10, etc.), the ESC key, or the DEL key. The exact key depends on your computer’s manufacturer, and it is often displayed on the screen during the startup process. If you’re not sure, consult your computer’s manual or the manufacturer’s website.

Step 2: Navigate to the Secure Boot Option

Once you are in the BIOS or UEFI settings, you need to find the Secure Boot option.

This option is typically located under the "Security", "Boot", or "Authentication" tab. Use the arrow keys to navigate through the menus and look for a setting named "Secure Boot", "Secure Boot Control", "Secure Boot Mode", or something similar.

Step 3: Enable Secure Boot

After locating the Secure Boot option, you will need to enable it.

Select the Secure Boot option and change its status to "Enabled". Depending on your system, you may need to use the enter key to open a submenu where you can change the setting.

Step 4: Save Changes and Exit

The final step is to save your changes and exit the BIOS or UEFI settings.

Look for an option that says "Save & Exit", "Exit Saving Changes", or something similar. Confirm that you want to save the changes you made and your computer will restart with Secure Boot enabled.

After you have enabled Secure Boot, your computer will be better protected against security threats. It will only allow software that is signed and trusted to run during the startup process. This can prevent malware from compromising your system before the operating system even loads.
