To enable Secure Boot on an ASUS laptop or desktop, you need to enter the BIOS/UEFI, switch to Advanced mode, and then turn on the Secure Boot option under the Security or Boot tab, saving changes before exiting so the setting actually takes effect.

What Secure Boot Does

  • Secure Boot checks bootloaders and drivers during startup and only allows those with trusted digital signatures to run, helping block rootkits and low-level malware.
  • On modern systems, Windows 11 and some anti-cheat or DRM systems require Secure Boot to be enabled for full compatibility and security features.

Basic ASUS Secure Boot steps

These steps are typical for many ASUS laptops and desktops, though the exact wording in BIOS may vary slightly by model.

  1. Enter BIOS/UEFI
    • Shut down the PC completely.
    • Power it on and repeatedly press F2 on a laptop, or Del/F2 on a desktop, until the ASUS BIOS screen appears.
  1. Switch to Advanced Mode
    • Press F7 or click Advanced Mode at the bottom of the BIOS screen.
  1. Find Secure Boot
    • On some ASUS laptops:
      • Go to the Security tab, then select Secure Boot.
 * On many ASUS desktops:
   * Go to the **Boot** tab, then select **Secure Boot**.
  1. Enable Secure Boot
    • If you see Secure Boot Control : set it to Enabled.
 * If you see **OS Type** : set it to **Windows UEFI mode** instead of **Other OS**.

 * Make sure the system is using **UEFI** (not Legacy) and that Compatibility Support Module (CSM) is disabled, as CSM often prevents Secure Boot from becoming active.
  1. Save and exit
    • Press F10 , confirm Save & Exit, and let the PC reboot.
 * After rebooting into Windows, you can confirm Secure Boot is on using the System Information app, which should show “Secure Boot State: On”.

If Secure Boot is greyed out

Sometimes the Secure Boot option cannot be changed until certain conditions are met.

  • Ensure Administrator/Supervisor password is set in BIOS on some models, which unlocks extra security settings including Secure Boot.
  • Disable Fast Boot and make sure CSM is disabled; these can interfere with toggling Secure Boot on some ASUS motherboards.
  • Confirm that the disk is set up for UEFI (GPT partition style); legacy/MBR setups may block Secure Boot on some configurations.
