How to Fix Secure Boot Not Working Issues in Windows 11: Step-by-Step Guide

Secure Boot is an important security feature in Windows 11 that helps protect your PC from malware during startup. Sometimes, users may encounter issues where Secure Boot is not working as expected. This can cause problems with system security and software compatibility.

Fixing Secure Boot issues usually involves checking BIOS settings and ensuring your system firmware supports it. With a few simple steps, you can troubleshoot and resolve most common problems.

This guide will walk you through each step in a clear and detailed way, so you can restore Secure Boot functionality on your Windows 11 PC. No advanced technical knowledge is required.

Let’s begin by understanding what you should verify before diving into the fixes.

Quick Note Before You Start

Before attempting to fix Secure Boot, please check the following:

  • Your PC supports Secure Boot: Most modern systems with UEFI firmware support Secure Boot. Older BIOS-only systems do not.
  • Windows 11 requires UEFI mode: Secure Boot only works when your system is booting in UEFI mode, not legacy BIOS mode.
  • Backup important data: Changing BIOS settings can sometimes cause boot issues. It’s safe to back up your important files first.
  • Access to BIOS/UEFI settings: You will need to enter your computer’s firmware settings to check and change Secure Boot options.

Step 1: Verify Secure Boot Status in Windows 11

Before making changes, check if Secure Boot is enabled or disabled in Windows:

  1. Press Windows + R to open the Run dialog.
  2. Type msinfo32 and press Enter to open System Information.
  3. In the System Summary, look for Secure Boot State.

If it says On, Secure Boot is enabled and working. If it says Off or Unsupported, you will need to troubleshoot further.

Step 2: Enter BIOS/UEFI Settings

Secure Boot is controlled from your PC’s firmware settings. To access these:

  1. Click Start and select Settings.
  2. Go to System > Recovery.
  3. Under Advanced startup, click Restart now.
  4. After restarting, select Troubleshoot > Advanced options > UEFI Firmware Settings.
  5. Click Restart to enter BIOS/UEFI.

Alternatively, you can press a specific key (like F2, Del, or Esc) during boot to access the BIOS, depending on your manufacturer.

Step 3: Enable UEFI Boot Mode

Secure Boot requires your PC to boot in UEFI mode. Here’s how to confirm or change it:

  • In BIOS/UEFI, look for the Boot tab or section.
  • Find the option labeled Boot Mode, Boot List Option, or similar.
  • Make sure it is set to UEFI and not Legacy or CSM.
  • Save your changes and exit BIOS (usually by pressing F10).

Switching to UEFI mode is essential because Secure Boot cannot function in legacy BIOS mode.

Step 4: Enable Secure Boot in BIOS/UEFI

Once UEFI mode is active, enable Secure Boot:

  1. Re-enter BIOS/UEFI settings (see Step 2).
  2. Navigate to the Security or Boot tab.
  3. Locate the Secure Boot option.
  4. Set Secure Boot to Enabled.
  5. If Secure Boot keys are required, choose to Install Default Keys or Reset to Factory Keys.
  6. Save changes and exit BIOS.

Enabling Secure Boot helps your system verify the integrity of the operating system during startup.

Step 5: Update Your BIOS/UEFI Firmware

If Secure Boot still doesn’t work, your BIOS/UEFI firmware may be outdated. Updating firmware can add compatibility and fix bugs:

  • Identify your motherboard or system model (found in System Information or on the device).
  • Go to the manufacturer’s official website.
  • Download the latest BIOS/UEFI update for your model.
  • Follow the manufacturer’s instructions carefully to update the firmware.

Firmware updates can improve Secure Boot support and overall system stability. Be cautious and follow instructions exactly to avoid system damage.

Step 6: Check for Windows Updates

Microsoft regularly releases updates that improve system features and security. To ensure Secure Boot works properly:

  1. Open Settings > Windows Update.
  2. Click Check for updates.
  3. Install all available updates and restart your PC if prompted.

Keeping Windows updated helps maintain Secure Boot compatibility and fixes related glitches.

Alternative Method: Disable and Re-enable Secure Boot

If Secure Boot seems stuck or unresponsive, try this alternative:

  1. Enter BIOS/UEFI settings.
  2. Disable Secure Boot and save changes.
  3. Restart your PC and enter BIOS again.
  4. Enable Secure Boot and save changes.
  5. Restart and check Secure Boot status in Windows.

This process can reset Secure Boot configurations and resolve minor issues.
