How to Enable Secure Boot on Your ASUS Device with Windows 11

How to Enable Secure Boot on Your ASUS Windows 11 Device

Looking to turn on Secure Boot on your ASUS computer running Windows 11? It’s not too tricky, but it does mean diving into your BIOS or UEFI settings — which can feel a bit intimidating at first. Enabling Secure Boot helps protect your system from sneaky malware and ensures only trusted software loads during startup. Here’s a straightforward guide to walk you through the process and keep that extra layer of security in place.

Restart and Access the BIOS

First up, restart your device. As soon as the screen goes dark, start pressing the F2 or Delete key (depends on your model; check your manual if unsure). Keep at it until you see the BIOS or UEFI menu pop up. Timing can be a bit tricky — if you miss it, your PC will boot into Windows instead, and that’s not what you want.
A hassle-free alternative? From within Windows 11:

  • Click the Start button or press Win + X
  • Select Settings
  • Navigate to System > Recovery
  • Under Advanced startup, click Restart now
  • When it restarts, go to Troubleshoot > Advanced options > UEFI Firmware Settings and click Restart

This method is often easier and less nerve-wracking than timing your key presses.

Navigating the BIOS/UEFI

Once you’re inside the BIOS/UEFI, proceed carefully. This is where mistakes can happen. Look for tabs labelled Security or Boot. Secure Boot options are usually located here. Some ASUS models feature graphical interfaces, making navigation a bit simpler, but stay attentive — menus can be a bit confusing.

Locating the Boot Settings

Search for a section related to boot options, often titled Boot or Boot Options. Use your arrow keys to navigate. If you’re unsure whether your system is in UEFI mode, you can check quickly via System Information:

  • Press Win + R and type msinfo32
  • Look for BIOS Mode — it should read UEFI

Enabling Secure Boot

Within the Boot settings, locate Secure Boot. If it’s currently set to Disabled, switch it to Enabled.
Not clickable? It might be greyed out, which usually indicates you’re in Legacy mode. To activate Secure Boot, you’ll need to switch from Legacy or CSM to UEFI. Head over to Boot Mode or Boot Priority to make that change.

Saving Your Changes

Once Secure Boot is enabled, find the option to save your settings — typically pressing F10 does the trick, or look for a Save & Exit option. Confirm when prompted by selecting Yes. Your PC will restart, and if all goes to plan, Secure Boot will now be active.
To verify in Windows, do this:

  • Open Windows Security (click the shield icon in the taskbar or go to Settings > Privacy & Security > Windows Security)
  • Select Device Security
  • Check under Core Isolation & Secure Boot for confirmation (if available)
  • Alternatively, run msinfo32 again and look for Secure Boot State; it should say On

Having trouble booting after this? Just revisit the BIOS to disable Secure Boot and troubleshoot from there.

Tips for Enabling Secure Boot

  • Make sure your BIOS is up to date before changing these settings. ASUS’s support site offers the latest firmware updates:

  • Back up any important data before tweaking BIOS settings — it’s a good safety net if things go awry.
  • If enabling Secure Boot causes issues, turn it off again and check for driver updates. Sometimes updating drivers solves compatibility problems.
  • Consult your specific ASUS model’s manual or official support pages if you get stuck.
  • For older machines stuck on Legacy mode, switching to UEFI is crucial for Secure Boot. You can do this with tools like mbr2gpt.exe:
    • Open Command Prompt or PowerShell as Administrator.
    • Run mbr2gpt /convert /allow-in-place.

Common Questions About Secure Boot on ASUS

What does Secure Boot do?

It ensures only trusted, verified software loads when your PC starts up — think of it as a bouncer checking IDs before letting anyone in.

Can older ASUS models use Secure Boot?

Not always. If your device doesn’t support UEFI firmware, it might not be possible. But firmware updates sometimes add support, so worth checking.

Will Secure Boot mess with my OS?

If set up correctly, it shouldn’t cause issues, but incompatible or unsigned drivers might trip you up. Make sure everything is compatible and signed before enabling it.

How do I check if Secure Boot is enabled?

Easy! Use msinfo32 again or look in the BIOS.

  • In System Information, look for Secure Boot State. If it says On, you’re good to go.
  • In BIOS, check under the Security or Boot tab.

What if my PC won’t boot after enabling Secure Boot?

If that happens, restart and go back into BIOS to disable Secure Boot.

  • Use Windows recovery options or go straight into UEFI settings.
  • Disable Secure Boot and see if that restores booting.

Then, troubleshoot any driver issues or verify hardware compatibility.

Quick Summary

  1. Restart your ASUS device.
  2. Enter BIOS/UEFI by pressing F2, Delete, or via the Windows Advanced Startup.
  3. Navigate to the Boot menu.
  4. If needed, switch to UEFI mode and turn on Secure Boot.
  5. Save your changes with F10 and restart.

In Closing

Enabling Secure Boot on your ASUS Windows 11 is well worth the effort — it provides peace of mind knowing your system only loads trusted software during startup. Follow these steps, and if you run into issues, just tweak the settings a bit. Remember to keep everything updated and back up your important data regularly.
