Battlefield 6 Secure Boot Error | Step-by-Step Fix Guide

The “Secure Boot error” in Battlefield 6 is a common issue for PC players. This error occurs because the game’s anti-cheat system requires Secure Boot to be enabled in your computer’s BIOS/UEFI settings.

If you receive this error, you need to enable Secure Boot to play the game.

Here’s how to resolve it:

Step-by-Step Fix Guide

1. Confirm the Issue

• Press Windows + R, type msinfo32, and hit Enter.

• Check:

  • BIOS Mode: should display UEFI

  • Secure Boot State: should display On

• If either is incorrect (e.g., Legacy, off, or unsupported), you’ll need to adjust BIOS settings.

2. Enable Secure Boot (Using BIOS/UEFI)

1. Restart your PC and enter BIOS/UEFI (commonly via F2, DEL, or ESC during boot).

2. Go to Boot or Security tab.

3. Ensure:

   • Boot Mode is set to UEFI, not Legacy or CSM.

   • Secure Boot is Enabled.

   • If the option is grayed out, try resetting Secure Boot keys to factory defaults, or toggling mode: switch from Setup to Custom, then back to Standard.

4. Enable TPM 2.0 (Intel PTT or AMD fTPM) if available.

5. Save changes and exit BIOS. Restart your PC.

3. Verify in Windows

• Repeat the msinfo32 check: confirm Secure Boot State: On and BIOS Mode: UEFI.
