You just want to play. You’ve got the latest hardware, the hype is real, and you finally click "Play" on Steam or the EA app. Then, it hits you. A cryptic popup window tells you that secure boot is not enabled battlefield 6 cannot launch. It’s frustrating. It feels like your computer is lying to you, especially if you know for a fact that your PC is modern.
This isn't just a random glitch. It’s a direct result of how modern anti-cheat systems, specifically EA Anti-Cheat (EAAC), interact with your motherboard’s firmware. Since the shift toward Windows 11 as the standard gaming OS, the requirements for "trusted" environments have become incredibly strict. If your BIOS isn't whispering the right secrets to your operating system, the game simply won't open.
Why EA Cares About Your BIOS Settings
Modern cheating has evolved. It’s no longer just simple memory hacks. High-level cheats now operate at the "kernel" level—essentially the basement of your operating system where the most sensitive data lives. To combat this, EA implemented a system that demands a chain of trust from the moment you hit the power button.
Secure Boot is a protocol where your PC’s firmware checks that the system boot loader is signed with a cryptographic key authorized by the hardware manufacturer. If Secure Boot is off, the anti-cheat assumes your system might be compromised by a "rootkit" or a hypervisor-based cheat. It’s a "guilty until proven innocent" approach. Honestly, it’s a bit of a headache for legitimate players who just happened to have an older BIOS configuration or a custom-built rig where these settings weren't toggled by default.
The Windows 11 Complication
Most people ran into this when upgrading. Windows 11 technically requires Secure Boot to install, but many users bypassed this using various workarounds or "Rufus" hacks. While Windows 11 might run fine without it, Battlefield 6's anti-cheat checks the hardware state directly. It doesn't care if Windows is happy; it cares if the hardware is locked down.

If you're on Windows 10, you might think you're safe. You're not. Even on the older OS, EA’s latest security updates for the Battlefield franchise have started enforcing these firmware checks to ensure a level playing field across the entire player base.
How to Actually Fix the Secure Boot Error
Fixing this isn't about changing a setting in the game menu. You have to go deeper. You need to enter your BIOS (Basic Input/Output System) or UEFI.
First, restart your computer. As it’s booting up, spam the Delete key or F2. Different motherboards use different keys. ASUS usually likes F2, while MSI and Gigabyte often prefer Delete. Once you’re in that scary-looking blue or black menu, don't panic. You're looking for a tab usually labeled "Boot" or "Security."
Switching from CSM to UEFI
This is the part where most people get stuck. If your BIOS is set to "CSM" (Compatibility Support Module), you cannot enable Secure Boot. CSM is an old-school mode that lets your PC act like a computer from 2010.
Go to the Boot tab. Find "CSM Support" and set it to Disabled.
Wait. Before you save and exit, there is a massive catch. If your hard drive was formatted using the old MBR (Master Boot Record) system, disabling CSM will make your computer stop booting into Windows entirely. You'll just loop back to the BIOS. If that happens, you’ll need to convert your drive to GPT (GUID Partition Table) using a tool like MBR2GPT in the Windows command prompt, but that’s a whole different rabbit hole. Assuming your PC is relatively new, it’s likely already on GPT.
Turning on Secure Boot
Once CSM is disabled, find the Secure Boot option. Set it to Enabled.
On some motherboards, like those from Gigabyte, you might see the status say "Enabled" but "Active: Off." This is maddening. To fix this, you often have to change the "Secure Boot Mode" from "Standard" to "Custom," then back to "Standard." It might ask you to "Install Default Factory Keys." Say yes. This loads the cryptographic keys that let Windows and the game’s anti-cheat verify your system is legit.
Common Obstacles and False Positives
Sometimes you do everything right and the secure boot is not enabled battlefield 6 error still haunts you. Why?

Sometimes the EA Anti-Cheat service itself is corrupted. Navigate to the game folder, find the installer folder, and look for the EA Anti-Cheat executable. Run it as an administrator and choose "Repair." This forces the software to re-scan your system's hardware state.
Another weird one? Overlays. Sometimes, third-party overlays from software like Discord or specialized GPU overclocking tools can interfere with the initial handshake between the anti-cheat and the BIOS. Try turning them off just to see if the game launches.
The "System Information" Check
Before you go tearing into your hardware, check what Windows actually sees.
- Press the
Windows Key. - Type
msinfo32and hit Enter. - Look for "BIOS Mode" and "Secure Boot State."
If BIOS Mode says "Legacy," you're in trouble—you'll need to reinstall Windows or convert your drive to GPT. If it says "UEFI" but Secure Boot says "Off," then a quick trip to the BIOS will fix your Battlefield 6 issues.
Beyond the Technical: Why This Matters for the Franchise
Let’s be real. Battlefield has had a rough time with cheaters in the past. Battlefield V and Battlefield 2042 were plagued by "rage hackers" flying around or shooting through walls. EA is betting the farm on this new security layer for Battlefield 6. By forcing Secure Boot, they are raising the "cost of entry" for cheat developers.
It’s a trade-off. We lose a bit of convenience and some older hardware support, but we gain a game where we aren't getting headshotted by a guy spinning in circles from across the map. Is it worth it? Most players would say yes, provided the fix actually works.
Actionable Steps for a Clean Launch
If you are staring at that error message right now, follow this exact sequence:
- Check your drive format: Open Disk Management, right-click "Disk 0," and check Properties > Volumes. If it’s MBR, don't touch BIOS yet. You need to convert to GPT first.
- Update your BIOS: Sometimes older BIOS versions have "broken" Secure Boot keys. Check your motherboard manufacturer’s website. A quick flash can solve everything.
- The "Factory Keys" Reset: Inside your BIOS, if Secure Boot is "Enabled" but not "Active," find the option to "Reset to Factory Keys" or "Restore Factory Keys." This is the most common fix for Gigabyte and ASUS boards.
- Clear the Cache: Delete the EA App cache. Sometimes the app "remembers" the error even after you've fixed the hardware setting.
- Run as Admin: Always ensure the EA App and the Battlefield 6 executable are running with administrative privileges to ensure they have the "clearance" to check your hardware status.
By ensuring your firmware is correctly configured and your cryptographic keys are properly installed, you bridge the gap between your hardware and the game's security requirements. This isn't just a suggestion from the developers; it's a hard gate. Once that gate is open, you can finally get back to the actual game.
