It’s pretty frustrating when you try to launch Battlefield 6 and get a Secure Boot error instead of the game. You click Play, but the EA Anti-Cheat stops everything because your PC isn’t meeting its security check. This guide explains what the Secure Boot error means, why it shows up, and how you can fix it fast so you can get back into the game.
What Is The Battlefield 6 Secure Boot Error?
Secure Boot is a Windows feature inside your UEFI firmware. It checks that your PC is running trusted system files. Battlefield 6 uses EA Anti-Cheat, and that anti-cheat needs Secure Boot to confirm your system hasn’t been modified.
You’ll see the error inside the EA App, the Origin launcher (if using the old client), or when the Battlefield 6 window tries to load. This happens on Windows 10 and Windows 11 across different motherboards like ASUS, MSI, Gigabyte, ASRock, and others.
Common Causes Of Battlefield 6 Secure Boot Error
This issue appears for different reasons depending on your system:
- Secure Boot is disabled in BIOS
- Your PC is using Legacy Boot instead of UEFI
- TPM 2.0 is turned off
- EFI partition is missing or corrupted
- Motherboard firmware is old
- Windows updates broke Secure Boot
- EA Anti-Cheat can’t verify your boot state
How to Fix Battlefield 6 Secure Boot Error?
These fixes depend on your hardware and Windows setup, but most players solve the error with the steps below.
Fix 1: Restart Into BIOS And Enable Secure Boot
Battlefield 6 anti-cheat checks if Secure Boot is active. If it’s off, the game blocks you.
Here are the following steps which help you turn it on:
- Restart your PC
- Press the BIOS key (Del, F2, F10, or Esc)
- Enter BIOS Setup
- Go to Security or Boot tab
- Look for Secure Boot
- Set it to Enabled
- Save and exit BIOS
- Try launching Battlefield 6 again
Fix 2: Switch Boot Mode From Legacy To UEFI
EA Anti-Cheat does not accept Legacy Boot. Battlefield 6 needs your system in UEFI mode.
Follow the steps below to check your boot mode:
- Open System Information in Windows
- Check BIOS Mode
- If it says Legacy, you must convert to UEFI
Converting usually requires GPT and not MBR. Windows has a tool called mbr2gpt, but use it carefully.
Fix 3: Enable TPM 2.0 (Intel PTT / AMD fTPM)
TPM 2.0 is part of the security system EA Anti-Cheat checks before launching Battlefield 6.
You can perform the following steps to enable TPM:
- Restart your PC and open BIOS
- Go to Security or Advanced settings
- Find Intel PTT (Intel CPUs) or AMD fTPM (AMD CPUs)
- Turn it on
- Save and exit
After that, launch Battlefield 6 again to see if the error is gone.
Fix 4: Reset Secure Boot Keys (Standard Keys)
Secure Boot needs security keys to verify Windows. If the keys are missing, Secure Boot fails.
Try these simple steps to reset keys:
- Boot into BIOS
- Find Secure Boot menu
- Select Install Default or Standard Keys
- Save and exit
This restores factory keys and often fixes the error.
Fix 5: Repair Windows Bootloader / EFI Partition
If the EFI partition is damaged, Secure Boot cannot verify Windows correctly. You can repair the boot files using Windows recovery tools. Open the Windows Recovery Environment and use Startup Repair. This usually fixes missing boot signatures.
Fix 6: Update Motherboard BIOS / UEFI Firmware
Old firmware sometimes can’t handle Secure Boot or TPM correctly. Updating UEFI often fixes the error.
Visit your motherboard brand website, download the latest BIOS update, and follow their instructions. After the update, try Battlefield 6 again.
Fix 7: Disable Fast Boot
Fast Boot skips some hardware checks. That can confuse Secure Boot and cause the error. Turn it off in BIOS, restart your PC, and try launching the game again.
Fix 8: Run Windows Update And Check Device Security
Windows updates install new Secure Boot signatures and anti-cheat support.
Open Windows Update, install available patches, then open Windows Security and check Device Security to confirm Secure Boot and TPM are active.
Fix 9: Reinstall EA Anti-Cheat
If EA Anti-Cheat fails to verify your boot state, you may need to reinstall it. Uninstall EA Anti-Cheat from the game folder, then launch Battlefield 6. It will reinstall automatically. This fresh install fixes signature issues.
Prevention Tips to Avoid Errors in Game
Keep your system stable with these habits:
- Keep BIOS and drivers updated
- Don’t switch to Legacy Boot
- Avoid deleting EFI partitions
- Keep TPM 2.0 enabled
- Install Windows updates often
- Avoid unsigned drivers
- Restart your PC after EA Anti-Cheat updates
Conclusion
The Battlefield 6 Secure Boot error usually appears because your system isn’t running in a verified mode. This can happen from wrong BIOS settings, disabled TPM, wrong boot mode, or corrupted boot files. Most players fix the error by enabling Secure Boot, switching to UEFI, or updating BIOS firmware.
Try the fixes one at a time until Battlefield 6 launches normally. If nothing works, contact EA Support or your motherboard manufacturer for help. And if this guide helped you, feel free to share it with other players.
