Secure Boot needs to be enabled in your PC’s BIOS/UEFI before launching Battlefield, and the exact steps depend on your motherboard/PC brand. Here’s a straightforward, practical guide you can follow. What Secure Boot is and why it matters
- Secure Boot is a UEFI feature that helps ensure your system boots with trusted software, which some modern games (including Battlefield editions) require for anti-cheat and security reasons. If Secure Boot is off or not properly configured, you may see startup errors or be blocked from launching the game. [Reasonable assumption for context, no external source cited here]
Steps to enable Secure Boot (general procedure)
- Reboot your PC and enter the BIOS/UEFI settings. Common keys to press during boot are F2, Del, Esc, or F10; the key varies by manufacturer. If unsure, check the on-screen prompt during startup or your PC’s manual.
- Ensure the system is using UEFI mode (not Legacy/CSM). In the BIOS, look for settings labeled Boot Mode, Boot Configuration, or something similar. Set it to UEFI only.
- Verify the drive is using GPT partitioning. Secure Boot typically requires GPT, not MBR. If your disk is MBR, you’ll need to convert it to GPT. This can be done without data loss on Windows using the MBR2GPT tool, or via Disk Management after backing up important data.
- Enable Secure Boot. Find the Secure Boot option, often under a Security, Boot, or Authentication tab, and set it to Enabled. If the option is greyed out, ensure you’re in UEFI mode and that the drive uses GPT.
- Save changes and reboot. Exit the BIOS/UEFI, choosing to save changes.
Troubleshooting common issues
- If the PC won’t boot after enabling Secure Boot, you likely have MBR/BIOS-compatibility issues. Convert the drive to GPT and switch back to UEFI if necessary, then re-enable Secure Boot.
- If you encounter a “Secure Boot not active” warning in-game, re-check that the system is in UEFI mode with a GPT disk, and that Secure Boot is set to Enabled.
- Some systems require additional TPM or virtualization-related settings (e.g., TPM 2.0, VBS/HVCI) to be enabled for compatibility with Battlefield 6; consult your motherboard/PC vendor’s guidance if you see those prompts.
Notes and caveats
- The exact menu labels and steps can vary by motherboard brand (ASUS, MSI, Gigabyte, Dell, HP, Lenovo, etc.). If you get stuck, search for “How to enable Secure Boot on [your motherboard model or PC brand]” for precise, brand-specific instructions.
- If you need to convert a Windows disk from MBR to GPT, back up important data first and use the recommended tool or command sequence for your OS version.
If you’d like, share your PC’s brand (or motherboard model) and your current boot mode (UEFI vs Legacy) and I can tailor the step-by-step instructions to your exact system.
