Battlefield 6 is utilizing a strong anti-cheat solution called Javelin that operates at the kernel level to prevent low-level cheat methods. Secure Boot must be enabled in your PC’s UEFI firmware for Javelin to function.
Secure Boot only blocks legally signed operating system drivers and pieces from boot time loading. It blocks rootkits and other abuse loading ahead of the OS—a major attack entry point for top-end cheat games. When Secure Boot is disabled, Battlefield 6 will not even launch, and you’ll receive an error message sending you here to this system requirement.
Step 1: Check Your Current Secure Boot Status
Please ensure you are asked to do this before proceeding any further and making the changes.
- First, you need to ensure if Secure Boot is already disabled or not.
- Press Windows + R to open the Run window.
- Type in msinfo32 and press the Enter button.
- In the System Information window, search for the following entries:
- BIOS Mode – Should be UEFI.
- Secure Boot State – Should be On.
If Secure Boot State shows “Off” or “Unsupported,” then you will have to do the following.
Step 2: Prepare Your System for Secure Boot
- Ensure That You’re Using UEFI and Not Legacy BIOS
- Secure Boot works only with UEFI and not with the older Legacy BIOS mode. If your BIOS Mode shows Legacy, you’ll have to switch over.
- Convert Your Drive to GPT From MBR
- Secure Boot also requires your boot drive to be in the GPT (GUID Partition Table) format, not MBR (Master Boot Record).
How to convert without data loss:
- Open Command Prompt as Administrator.
- Run below command to validate:
bash
CopyEdit
mbr2gpt /validate /disk:0 /allowFullOS
- If validation, convert the drive:
bash
CopyEdit
mbr2gpt /convert /disk:0 /allowFullOS
- Restart your PC later and boot in UEFI firmware to change the boot mode from Legacy BIOS to UEFI.
Step 3: Configure Secure Boot in UEFI Firmware
Having verified that your machine boots in UEFI mode and from a GPT boot disk, you can now enable Secure Boot.
Accessing UEFI Firmware Settings
There are two methods in general to get into your UEFI/BIOS settings:
Method 1: From Windows
- Open Settings > System > Recovery (or Update & Security > Recovery in Windows 10).
- Click Restart now under Advanced startup.
- Restart at startup, and then press Troubleshoot > Advanced options > UEFI Firmware Settings.
Method 2: At Boot
- Restart your system.
- Press the BIOS access key (usually Del, F2, or F10) repeatedly during booting until you can see the firmware screen.
- In firmware setup, look for the Boot, Security, or Authentication tab—according to your motherboard brand.
- Enabling Secure Boot
- Find the Secure Boot option.
- Switch it to Enabled.
If it is grayed out, you might need to:
- Set a Supervisor or Admin Password first.
- Restore Factory Keys for Secure Boot.
- Change OS Type to Windows UEFI Mode.
- Save changes and reboot the firmware setup (typically with the F10 key).
Step 4: Secure Boot Must Be On
Restart once again into Windows and Open System Information window (msinfo32).
Make sure that:
- BIOS Mode = UEFI
- Secure Boot State = On
- If these are all set correctly, your system should now have Secure Boot enabled and Battlefield 6 should now run normally.
What If Secure Boot Is Not Available?
If Secure Boot is still marked as Unsupported or doesn’t show up at all:
Your machine might not be Secure Boot capable. This is common with pre-2012 machines.
You might have to get an update of firmware from your machine or motherboard manufacturer.
If you’re gaming on Linux, SteamOS, or Steam Deck—Secure Boot isn’t supported, and Battlefield 6 isn’t supported on any of them due to the anti-cheat limitations.
Secure Boot will be a scary thing to turn on for some of you, but it’s something you’ll have to do in order to turn on Battlefield 6’s anti-cheat technology. The good news is that most gaming PCs nowadays are compliant, and it’s typically an easy thing once you know how to do it.
If you are simply installing a new system or upgrading to Battlefield 6, make sure your storage and motherboard are already on UEFI mode with GPT partition, and you should not have any problems.
