1. Why is Battlefield 2042 not working?

Since late 2023, EA’s anti-cheat requires that Secure Boot is enabled on your system for Battlefield 2042 to run. If it’s not enabled (or you're using Legacy BIOS mode), the game will refuse to launch.

2. What is Secure Boot?

Secure Boot is a security feature in your PC’s UEFI/BIOS that only allows signed software to run during startup. It helps prevent cheats and rootkits from injecting at boot level — which is why EA Anti-Cheat now requires it.

3. How to Fix: Enable Secure Boot to Launch Battlefield 2042

Step 1: Check if You’re Using UEFI

1. Press Win + R, type msinfo32, hit Enter.

2. Look for BIOS Mode:

• If it says UEFI → you can enable Secure Boot.
• If it says Legacy → you’ll need to reinstall Windows in UEFI mode. (Secure Boot won’t work in Legacy mode.)

Step 2: Enter Your BIOS/UEFI

1. Restart your PC.

2. During startup, repeatedly press the key for BIOS (usually Del, F2, F10, or Esc depending on your motherboard).

3. Once in BIOS, look for the Secure Boot setting under the Boot, Security, or Advanced tab.

Step 3: Enable Secure Boot

1. Make sure CSM (Compatibility Support Module) is disabled — Secure Boot won’t activate with CSM on.

2. Set Secure Boot to Enabled.

3. If needed, change OS Type to “Windows UEFI mode.”

4. Save and exit (usually by pressing F10).

Step 4: Reboot and Launch the Game

After enabling Secure Boot, launch Battlefield 2042 again. The error should be gone, and the anti-cheat will now load properly.

Final Tip

Once you switch to UEFI mode and enable Secure Boot, Battlefield 2042 should work normally.
