Step 1: Check if Your PC Supports Secure Boot
Method 1 – Windows System Information
  1. Press Windows key + R.

  2. Type msinfo32 and press Enter.

  3. Look for BIOS Mode and Secure Boot State.

    • UEFI + Off → Supported, needs enabling in BIOS.

    • UEFI + On → Already active.

    • Legacy → Not supported until Windows is reinstalled in UEFI mode with a GPT disk.

    Method 2 – Check Partition Style

    1. Press Windows key + X → Disk Management.

    2. Right-click your boot drive (C:) → Properties → Volumes tab.

    3. Look for Partition Style:

      • GPT → Compatible.

      • MBR → Needs conversion to GPT (backup and reinstall or use conversion tools).

      If your system is not UEFI or is MBR-formatted, you must fix that before Secure Boot will work.
Step 2: Enable Secure Boot in BIOS
  • Restart your PC and press the BIOS/UEFI access key (Esc, F1, F2, Del, F10 depending on brand).

  • Go to the Boot or Security tab.

  • Set Secure Boot to Enabled.

  • If available, set Secure Boot Mode to Standard or Windows UEFI Mode.

  • Save changes and exit.
Step 3: Confirm Secure Boot in Windows
  1. Launch Command Prompt as administrator.

  2. Run this command:
    powershell Confirm-SecureBootUEFI

    • If output shows True, Secure Boot is active.
    • If False, return to UEFI and confirm you saved the setting correctly.
Step 4: Update Graphics Drivers
  • Secure Boot can block unsigned drivers. Use drivers signed by Microsoft.

  • Open Device Manager.

  • Expand Display adapters.

  • Right-click your GPU → Update driver → Search automatically.

  • Confirm the update is signed in driver details. If unsigned, go to your GPU vendor’s website and download the latest signed driver manually. Examples:

  • Nvidia: Driver Page [www.nvidia.com]

  • AMD: Driver Page [www.amd.com]
Step 5: Verify Game Files in Steam
  • Launch Steam.

  • Go to your Library → right-click Battlefield 6 → Properties.

  • Choose Installed Files → Verify integrity of game files.

  • Steam confirms all files remain signed and intact.
Step 6: Launch Battlefield 6 with Secure Boot Active
  • Secure Boot helps block tampered game or mod files.

  • Open Battlefield 6 in Steam.

  • Monitor for errors. If the game fails to launch:
    - Return to BIOS and toggle Secure Boot off.
    - Test again. If the game demands Secure Boot to be off, follow developer guidance.
Step 7: Maintain System Integrity
  • Use only Microsoft-signed drivers and updates.

  • Avoid unsigned kernel modules or patches.

  • Use tools like sfc /scannow or DISM /Cleanup-Image to verify system files stay clean.
Checklist
  • Secure Boot enabled in BIOS/UEFI
  • Windows confirms Secure Boot true
  • Graphics drivers signed and updated
  • Battlefield 6 game files verified in Steam
  • Game launches without conflict under Secure Boot
  • No unsigned components in your system
Troubleshooting
  • Recheck BIOS settings for Standard/Windows UEFI mode.
  • Verify game files in Steam again.
  • Update all drivers with Microsoft-signed versions.
  • Remove mods, overlays, or unsigned software.
  • If it only runs with Secure Boot off, an unsigned driver or anti-cheat issue is likely. Contact EA Support.
Incompatability?
in some cases your PC might be incompatible with Secure Boot for Battlefield 6.

Reasons include:
  • Legacy BIOS instead of UEFI firmware. Secure Boot only works with UEFI.
  • Boot drive formatted as MBR instead of GPT. Secure Boot requires GPT.
  • Unsigned hardware drivers for critical components like GPU or storage controllers.
  • Old hardware that lacks firmware support for Secure Boot.
  • Custom hardware mods or unsupported PCIe devices.
