Background: Battlefield 2042’s Secure Boot Mandate​

When Battlefield 2042 launched, its anti-cheat protocols were in line with industry standards, utilizing advanced software to detect unfair play. However, as sophisticated cheats began slipping past defenses, developers responded with v8.8.0—a patch that enforces Secure Boot activation at the hardware level. This shift aims to close loopholes exploited by rootkit-level cheats that load before Windows boots, evading detection entirely.
Secure Boot works by leveraging the Unified Extensible Firmware Interface (UEFI) to ensure that only trusted, signed software is allowed to run when a PC starts up. By requiring this setting, Battlefield 2042 raises the bar for cheaters, but it also adds a new technical barrier for the average user.

Understanding Secure Boot and Why It’s Required​

What Is Secure Boot?​

Secure Boot is a security standard embedded within UEFI firmware. When enabled, Secure Boot checks each piece of boot software—including the operating system loader and drivers—against a database of approved signatures stored in the PC’s firmware. If unsigned or tampered code attempts to load, Secure Boot blocks the process, halting potentially malicious activity at startup.

Why Is It Required for Battlefield 2042?​

The reasoning is straightforward: modern cheats often employ kernel-level drivers or rootkits that inject themselves at or before boot, bypassing traditional anti-cheat tools. By requiring Secure Boot, EA effectively blocks these advanced attack vectors, as unsigned cheats can no longer run.

• Anti-rootkit defense: Eliminates a major class of cheats that operate outside Windows security boundaries.
• Enhanced trust: Players can be more confident matches are fair.
• System-wide protection: Secure Boot increases security for all users, not just gamers.

Step-by-Step: Enabling Secure Boot on Your Windows PC​

For many, Secure Boot is already active and no further steps are required. For the unlucky minority, getting it operational might seem daunting, especially given the technical jargon and BIOS intricacies involved. Here’s an actionable guide tailored for both tech-savvy users and newcomers.

Preliminary Checks​

Before diving into BIOS, determine if Secure Boot is already enabled:

• Press Windows + R to open the Run dialog.
• Type msinfo32 and hit Enter to launch System Information.
• In the window, look for:
• BIOS Mode: Must state UEFI (not Legacy or CSM).
• Secure Boot State: Must be On.

If both are correct, Battlefield 2042 should launch without error. If not, proceed to the enabling steps below.

---

Preparing Your System​

Secure Boot only functions in UEFI mode and requires a GUID Partition Table (GPT) rather than the older Master Boot Record (MBR).

• UEFI Boot Mode: Required, not Legacy or CSM.
• Partition Style: GPT, not MBR.
• TPM 2.0: Strongly recommended (required for some features).
• Legacy/CSM: Must be disabled.

Convert MBR to GPT (If Needed)​

If your disk uses MBR, Secure Boot cannot be enabled. Converting to GPT can be accomplished via the Windows MBR2GPT tool:

• Open Command Prompt as Administrator.
• Type mbr2gpt /convert /allowFullOS and hit Enter.
• Reboot and continue the BIOS configuration.

This process is generally non-destructive, but backing up data is always recommended.

Enabling Secure Boot via UEFI/BIOS​

Every PC manufacturer customizes UEFI menus, but the fundamentals are largely similar. The following procedure applies to most desktops and laptops from ASUS, MSI, Gigabyte, Dell, HP, Lenovo, and more.
Estimated time: About 6 minutes

• Restart your PC. Immediately press the BIOS entry key (DEL, F2, F10, etc.) as the manufacturer’s logo appears.
• Switch to UEFI Mode:
• Navigate to Boot settings.
• Change Boot Mode or Launch CSM to UEFI (sometimes labeled “Windows UEFI Mode” or “UEFI Only”).
• Disable Legacy/CSM:
• Locate “CSM” or “Legacy Boot.”
• Set to Disabled.
• Enable Secure Boot:
• Go to the Security or Boot tab.
• Find “Secure Boot Control” or “Secure Boot” and set to Enabled.
• Load Factory Keys (if prompted):
• If Secure Boot is greyed out or in “Setup Mode,” select “Restore Factory Keys” or “Enroll All Factory Keys.”
• This will populate the key database and switch Secure Boot from Setup Mode to Standard/User Mode.
• Save and Exit:
• Press F10 or use the Exit menu.
• Choose Save Changes and Exit.
• The PC will reboot with Secure Boot active.

Note: On certain brands like HP and Lenovo, Secure Boot remains greyed out until boot mode is switched to UEFI and factory keys are loaded.

Verifying Secure Boot Activation​

Once your system reboots:

• Open the Run dialog (Windows + R), type msinfo32, and hit Enter.
• Check:
• BIOS Mode: Should read UEFI.
• Secure Boot State: Should read On.

If so, Battlefield 2042 should allow access. If Secure Boot still displays as “Off,” re-examine the BIOS settings or revisit the prerequisites.

---

Troubleshooting Common Issues​

While enabling Secure Boot is straightforward for most, some systems present unique challenges that require additional steps or vigilance.

Secure Boot Option Is Greyed Out​

• BIOS Not in UEFI Mode: Switch from Legacy/CSM to UEFI.
• Missing Factory Keys: Initiate “Restore Factory Keys” or similar option.
• Unsupported Hardware: Some older motherboards (pre-2012) lack UEFI or Secure Boot support.

BitLocker Prompts​

If you use BitLocker drive encryption, changing BIOS settings can trigger a BitLocker recovery key request at next boot. Always ensure you know your recovery key before modifying Secure Boot or boot device configurations.

Disk Still Uses MBR​

Secure Boot cannot function with MBR partitions. Use Disk Management (right-click Start > Disk Management > Disk Properties > Volumes Tab) to check partition style and convert if needed.

BIOS Reverts Settings​

Some systems automatically switch back to Legacy/CSM after reboot if the disk isn’t GPT or if incompatible boot media is detected. Confirm all prerequisites before enabling Secure Boot.
