Secure Boot issues with Battlefield 6 typically come from mismatches between your PC’s firmware settings and the game’s anti-cheat requirements. The general fix is to ensure your system is using UEFI boot, the disk is GPT, and Secure Boot is enabled, with TPM/TPM2.0 active when required by the anti- cheat. What to check and steps to try
- Verify your system is booting in UEFI mode
- In Windows, run msinfo32 and look for “BIOS Mode: UEFI.” If it shows Legacy, you’ll need to switch to UEFI, which may require converting the system disk to GPT.
- Ensure the boot disk is GPT
- If your disk is MBR, convert to GPT safely (e.g., using built-in tooling in Windows such as mbr2gpt) before enabling Secure Boot.
- Enable Secure Boot in BIOS/UEFI
- Enter your motherboard’s firmware interface during boot (commonly F2, Del, or Esc). Find Secure Boot and enable it.
- If there is an OS Type option, set it to Windows UEFI Mode or a similar Windows-friendly setting.
- Disable CSM/Legacy support to enforce full UEFI mode if available.
- Enable TPM 2.0 or equivalent
- In BIOS/UEFI, turn on TPM 2.0 (AMD fTPM or Intel PTT) as required by the anti-cheat.
- Return to Windows and verify
- After applying BIOS changes, boot into Windows and confirm Secure Boot is enabled and the disk is GPT. You can check Disk Management (diskmgmt.msc) to see if the boot drive is GPT.
- Reinstall or repair if needed
- If Battlefield 6 still reports Secure Boot is not enabled, consider repairing the game files via your platform (EA app/Steam) and ensure there are no BIOS passwords or Secure Boot key policies blocking the boot process.
Common caveats
- Some systems with certain OEM configurations or older hardware may have Secure Boot options greyed out until other settings are adjusted (e.g., enabling TPM, setting OS Type to Windows UEFI, or switching from Compatibility Support Module to pure UEFI).
- If the system previously used Legacy BIOS with MBR and you don’t want to or cannot convert, you may need to back up data and perform a clean OS install in UEFI mode with a GPT disk.
- After changing firmware settings, ensure you save changes and reboot completely; partial or failed reboots can lead to black screen or boot loops.
If you’d like, share details about your PC model, motherboard/firmware brand, current BIOS/UEFI options available, and whether your Windows installation is on a GPT disk or MBR. With that, a more precise, step-by-step checklist tailored to the exact BIOS layout can be provided.
