Secure Boot is a security feature in UEFI (Unified Extensible Firmware Interface) that ensures only trusted software can boot on a PC. Battlefield 6 requires Secure Boot to be enabled to prevent cheating by enforcing trusted boot processes. If Battlefield 6 shows a Secure Boot error, enabling Secure Boot in your BIOS/UEFI settings is necessary. To enable Secure Boot for Battlefield 6:
- Enter BIOS/UEFI setup by pressing a key during startup (commonly F2, DEL, ESC, or F10 depending on the motherboard).
- Set boot mode to UEFI (not Legacy or CSM).
- Enable Secure Boot (may be under Security, Boot, or Authentication tab).
- Install default Secure Boot keys if available, then save and exit.
- Confirm your boot disk uses GPT format, not MBR. If MBR, convert it to GPT using Windows tools (e.g., the mbr2gpt command).
- Check Secure Boot state is "On" in Windows by running msinfo32.
If Secure Boot is disabled or not properly configured, Battlefield 6 will not launch. Additionally, TPM 2.0 is also often required together with Secure Boot for the game’s anti-cheat protection. This process enhances PC security by preventing rootkits and boot-time malware, which is why it’s mandated by Battlefield 6 for a secure and fair gaming experience. If issues persist after enabling Secure Boot, checking motherboard-specific details and BIOS updates is recommended.
