How To Enable Secure Boot to Play Battlefield 2042 on PC (Anti-Cheat Solution)

Okay, so if you’re trying to run Battlefield 2042 after that recent v8.8.0 update, you might run into the annoying requirement that Secure Boot has to be turned on. It’s kind of wild, but basically, this is part of EA’s anti-cheat system now, which means if Secure Boot is off, the game just refuses to launch without warning. No one told me how tricky this could be until I had to mess with BIOS settings myself. The good news? It’s mostly straightforward—assuming you’re comfortable poking around in BIOS and Windows. This little guide will walk you through checking if Secure Boot is enabled and, if not, how to turn it on. Get this done, and Battlefield should start up without that little “secure boot required” error.

How to Enable Secure Boot for Battlefield 2042

Check If Secure Boot Is Already Enabled

First things first, before diving into BIOS, it’s worth verifying whether Secure Boot is actually active. Sometimes, it’s technically enabled but not fully operational, which can cause confusion. Usually, the quickest way is through Windows info:

• Press Windows + R, type msinfo32, and press Enter.
• In the System Information window, look for BIOS Mode—it should say UEFI. If it’s on Legacy or CSM, Secure Boot probably isn’t supported or configured properly.
• Check the Secure Boot State — it should say On. If it’s Off or Disabled, then that’s your problem.

On some setups, Secure Boot might show as enabled but still not work properly, especially if the system is in Setup Mode instead of User Mode. If that’s the case, the next fixes will help.

How to Enable Secure Boot for Battlefield 2024?

Enabling Secure Boot isn’t exactly a walk in the park for everyone. Each motherboard brand has its quirks, but generally, it involves entering BIOS, switching some settings, and saving. Be aware that on some systems, you need to disable Legacy Boot (or CSM) first, then enable Secure Boot. Also, it’s a good idea to be prepared—back up your data if possible—because BIOS fiddling always carries a tiny risk of misconfiguration.

Here’s the usual process:

Time needed: about 6 minutes, maybe less if you’re experienced.

1. Enter BIOS/UEFI
• Restart your PC and keep pressing the BIOS key (it’s usually DEL, F2, or F10) right after the machine starts booting, until you see BIOS settings. If you’re not sure, check your motherboard’s manual or look up your brand online. It’s often a quick Google.
2. Switch to UEFI Mode
• In BIOS, find the “Boot” tab or something similar. Look for “Boot Mode, ” “Boot Priority, ” or “UEFI/Legacy Boot.” Switch it to UEFI. If you see an option called “Windows UEFI Mode” or simply “UEFI only, ” select that.
3. Disable Legacy/CSM
• Locate options like “Launch CSM” or “Legacy Boot” and set them to Disabled. This is crucial because Secure Boot prefers UEFI-only firmware.
4. Enable Secure Boot
• Go to the Security or Boot tab.
• Find “Secure Boot Control” or simply “Secure Boot” and set that to Enabled. Sometimes it’s greyed out if Secure Boot is disabled or in setup mode.
5. Load Factory Keys if Needed
• If Secure Boot is greyed out, look for options like “Restore Factory Keys” or “Enroll All Factory Keys.” This switches Secure Boot from a setup mode (where nothing is trusted) to the normal user mode.
6. Save & Exit
• Press F10 or go to the Exit menu and select “Save Changes and Exit.”
• Your PC will reboot, ideally with Secure Boot now turned on.

Sometimes, BIOS interfaces look different—especially on brands like HP, Lenovo, or custom builds. On some systems like Dell or ASUS, you might see a Secure Boot toggle directly. On others, you might need to toggle the “Secure Boot Mode” between “Setup” and “User”—just making sure it’s set to User mode is what counts.

Prerequisites Before Enabling Secure Boot

This whole Secure Boot thing only works smoothly if your system’s configured right. Here’s what to check before you get started:

• UEFI Boot Mode Must Be Enabled

Check in the BIOS if your Boot Mode is UEFI—not Legacy or Compatibility Support Module (CSM).Also, in Windows, you can verify this via Disk Management:

• Open Disk Management by right-clicking on the start button and selecting Manage Disks.
• Right-click your system drive and choose Properties.
• Go to the Volumes tab and look at Partition Style. If it says GPT, you’re good. If it’s MBR, you’ll need to convert it to GPT, which can be a pain without reinstalling. Tools like MBR2GPT make this easier.

If you’re unsure whether your BIOS supports UEFI or if it’s outdated, best to check the manufacturer’s site or update your BIOS first. Of course, that always comes with some risk, so proceed carefully.

• TPM 2.0 Module Is Recommended

Secure Boot isn’t just UEFI—having Trusted Platform Module (TPM) 2.0 is kinda recommended, especially on newer systems. Check if TPM is active by typing tpm.msc in the Run box (Windows + R).If it’s not enabled, reboot, head into BIOS, and enable “fTPM” (for AMD) or “PTT” (Intel).

• Disable CSM or Legacy Support

This is often the final barrier, especially on non-UEFI systems. Find the “CSM” or “Legacy Boot” options in BIOS and turn them off. On some motherboards, this disables Secure Boot until you re-enable it from scratch, so double check.

Final Check: Is Secure Boot Active?

Reboot after all this, then verify again:

• Press Windows + R, type msinfo32, press Enter.
• Make sure the BIOS Mode is UEFI and Secure Boot State says On.

If both are correct, your game shouldn’t complain anymore about Secure Boot. You’re ready to go.

Troubleshooting Tips

• Secure Boot still off? Revisit BIOS and double-check if settings stuck, or maybe your disk is still in MBR. Sometimes, Windows needs a reboot or BIOS reset.
• BitLocker users: If your drive is encrypted, BIOS changes might ask for your recovery key, so keep that handy.
• Older machines: Slower hardware or older BIOS versions might lack proper UEFI support or Secure Boot options; check for BIOS updates.

Once Secure Boot is active, Battlefield 2042 will stop giving you that error about anti-cheat. It’s kinda satisfying, but honestly, it feels like a lot just to play a game—because of course, Windows has to make it harder than necessary. Still, this method works on most systems, and once it’s set, it’s a one-and-done deal.
