Fixed : Battlefield 6 Secure Boot Not Enabled but it is Enabled in Bios

October 11, 2025 Freddy Error Fix 0

If you’re getting the “Secure Boot not enabled” error in Battlefield 6, even though Secure Boot is enabled in your BIOS because of a mismatch between your system’s boot configuration and what the anti-cheat is looking for.

Here’s what’s going on and how to fix it:

🧠 Why This Happens

Battlefield 6 (and some other modern games using EA Anti-Cheat or Denuvo) checks for Secure Boot status as part of its anti-cheat verification. However:

  • Even if Secure Boot is enabled in the BIOS, Windows might not detect it properly if:

    • The system was originally installed in Legacy (MBR) mode, not UEFI (GPT)

    • Boot keys or Secure Boot certificates are missing

    • There’s a glitch in the anti-cheat detection

✅ Fixes That Work for Most Users

🔹 1. Check If Secure Boot is Actually Active in Windows

Even if BIOS says it’s “Enabled,” Windows may not actually be using it.

Do this:

  1. Press Windows + R → type msinfo32 → Enter

  2. Look for Secure Boot State

    • If it says ON → you’re fine

    • If it says OFF or Unsupported → there’s an issue

🔹 2. System Was Installed in Legacy Mode (MBR), Not UEFI (GPT)

Secure Boot requires Windows to be installed in UEFI mode, not Legacy.

Check:

  1. In msinfo32, look at BIOS Mode

    • If it says Legacy, Secure Boot won’t function even if enabled in BIOS.

Fix:

  • You’ll need to convert your disk from MBR to GPT and reinstall or repair Windows in UEFI mode. This is a bit advanced but here are your options:

    ✅ Use MBR2GPT tool (safe, command-line utility):

    mbr2gpt /convert /allowfullos

    ⚠️ This only works if your partition structure is compatible. Backup your data first!

🔹 3. Clear Secure Boot Keys and Reinstall Them

Sometimes Secure Boot keys are missing or corrupted.

How:

  1. Reboot into BIOS

  2. Navigate to Secure Boot > Key Management

  3. Select Clear Keys

  4. Then choose Install Factory Default Keys

  5. Save and Exit

Boot into Windows and recheck msinfo32.

🔹 4. Disable and Re-Enable Secure Boot

  • Disable Secure Boot in BIOS

  • Boot into Windows normally once

  • Then restart and re-enable Secure Boot

  • This can help the system reinitialize detection

🔹 5. Run EA App as Administrator

If Secure Boot is properly enabled, but Battlefield 6 still throws an error:

  1. Right-click the EA App shortcut

  2. Click Run as administrator

  3. Launch the game from the EA App directly

🔹 6. Check for TPM and Platform Trust

Some Secure Boot checks rely on TPM 2.0 or Platform Trust being enabled.

  • In BIOS: look for TPM / fTPM and ensure it’s Enabled

  • On Intel, this may be called PTT (Platform Trust Technology)

🔹 7. Reinstall EA Anti-Cheat

  1. Navigate to:

    C:\Program Files\EA\AC

  2. Run the Uninstall.exe

  3. Reboot

  4. Launch Battlefield 6 again — it should reinstall EA Anti-Cheat

🛠 Final Option: Reinstall Windows in UEFI Mode (if in Legacy)

If your BIOS is in UEFI but Windows was installed in Legacy, games won’t detect Secure Boot.

You’ll need to:

  • Backup your data

  • Boot from a UEFI USB installer

  • Reinstall Windows using GPT partition scheme
