To secure boot Battlefield (specifically Battlefield 6, as the requirement is prominent for this game), you need to enable Secure Boot in your PC's BIOS/UEFI settings. Here's a step-by-step guide:
- Restart your PC and enter BIOS/UEFI setup by pressing the designated key during boot (commonly F2, DEL, ESC, or F10 depending on your motherboard or laptop brand).
- In BIOS, locate the Boot Mode or Boot Configuration setting and set it to UEFI mode, not Legacy or CSM.
- Find the Secure Boot option, usually under the Security, Boot, or Authentication tab, and set it to "Enabled." If this option is greyed out, ensure your system is using UEFI mode and that your boot disk is formatted with the GPT partition scheme (not MBR).
- Install default Secure Boot keys if prompted.
- Save your changes and exit BIOS (often by pressing F10).
- After booting into Windows, verify Secure Boot status by running "msinfo32" to open System Information and look for Secure Boot State—it should be "On."
If your disk is in MBR format and Secure Boot fails to enable, you will need to convert it to GPT. You can convert using the built-in Windows tool with the following commands in an elevated Command Prompt:
- mbr2gpt /validate /allowFullOS
- mbr2gpt /convert /allowFullOS
Then reboot and enforce Secure Boot again. Battlefield requires Secure Boot to prevent cheating by ensuring only trusted software loads during boot. It works alongside TPM and other anti-cheat measures. In summary:
- Enter BIOS/UEFI
- Switch Boot Mode to UEFI
- Enable Secure Boot and install keys
- Ensure disk is GPT, converting if necessary
- Save and reboot
- Verify Secure Boot is active in Windows
This will secure boot Battlefield and allow you to launch and play the game without Secure Boot errors.
