Battlefield 6 How to Enable Secure Boot

08 Oct 2025

Turning on Secure Boot is the fastest way to stop Battlefield 6 from throwing anti-cheat errors and refusing to launch. This guide explains step by step how to check your Secure Boot status, enable it safely in BIOS/UEFI, fix common issues, and make sure everything works before jumping into matches.

Key Takeaways

Secure Boot is mandatory for Battlefield 6. EA Anti-Cheat will not initialize without it.
Check your status first with msinfo32 before touching BIOS settings.
UEFI only: Disable Legacy/CSM and ensure your boot drive uses the GPT partition style.
Most “toggle missing” issues = MBR disk. Convert to GPT to unlock Secure Boot.
After enabling, reboot twice. Some systems register Secure Boot only after the second cycle.
Once Secure Boot is active, Battlefield 6 launches cleanly with no anti-cheat pop-ups.

Why Secure Boot Matters for Battlefield 6

If you’re seeing “EA Anti-Cheat requires Secure Boot to be enabled,” your motherboard’s firmware security isn’t active. Secure Boot, part of UEFI, ensures your PC loads only trusted, signed code at startup. For Battlefield 6, this means:

EA Anti-Cheat depends on it. Without Secure Boot, integrity checks fail and the game won’t start.
It prevents tampering. Unsigned bootloaders, shady drivers, or rootkits are blocked.
It stabilizes your launch. No more error loops or stuck loading screens.

Bottom line: enable Secure Boot to keep your system secure and let Battlefield 6 run smoothly.

How to Check if Secure Boot Is Enabled

Press Win + R, type msinfo32, and hit Enter.
In System Information, find Secure Boot State on the right side.

You’ll see one of the following:

On — Secure Boot is enabled. You’re done.
Off — Supported but disabled. Enable it in BIOS/UEFI.
Unsupported — Your system uses Legacy BIOS or MBR.

Tip: “Unsupported” rarely means your hardware can’t do it — usually you just need UEFI + GPT.

How to Enable Secure Boot in BIOS/UEFI

If your status is Off or Unsupported, follow these steps:

Restart your PC and press Del, F2, or F10 to open BIOS.
Go to the Boot, Security, or Authentication tab.
Find Secure Boot and toggle it from Disabled to Enabled.
If it’s greyed out, disable Legacy/CSM to enforce UEFI mode.
Save changes and reboot (usually F10).

Heads-up: Some BIOS setups hide Secure Boot until UEFI mode and GPT are enabled. MBR drives won’t support Secure Boot.

Common Issues When Enabling Secure Boot

Option greyed out: Legacy/CSM still enabled. Turn it off and reboot.
Windows says “Unsupported”: Convert your drive to GPT using mbr2gpt.
Game still errors: Reboot twice, then repair EA Anti-Cheat via EA App or Steam.
No Secure Boot option: Update your BIOS firmware.
PC won’t boot: Check “Windows Boot Manager” and reinstall default keys.

Troubleshooting: Battlefield 6 Still Won’t Launch?

Restart twice. Some firmware locks settings on the second reboot.
Repair EA Anti-Cheat: EA App → Manage → Repair.
Run as admin: Right-click → Run as Administrator.
Update BIOS & Windows.
Recheck status: If “Off” again, disable CSM.
Reinstall Anti-Cheat: Uninstall, reboot, reinstall clean.

Tip: Windows 11 users have fewer problems — Secure Boot is on by default. On Windows 10, recheck it after major updates.

How do I verify Secure Boot is working?

Press Win + R → msinfo32 → check “Secure Boot State.” If it says On, you’re set.

Does Secure Boot affect performance?

No. It only protects the startup chain — it doesn’t touch CPU/GPU performance.

I don’t see Secure Boot in BIOS — what now?

Enable UEFI mode and ensure your boot drive uses GPT. The option appears once Legacy mode is disabled.
