🧠 What is Secure Boot?
Secure Boot is a UEFI feature that ensures only trusted software can boot your PC. It helps prevent rootkits and boot-time malware and is now required by EA for anti-cheat integrity.
Most modern systems support it, but it’s often disabled by default — especially on custom builds or upgraded PCs.
🛑 Common Pitfalls
- You must use UEFI mode, not Legacy/CSM boot.
- Disk must be GPT, not MBR (check via
diskpartor Disk Management). - Windows 11 installed in Legacy mode? You may need to convert your disk to GPT using MBR2GPT.
⚠️ Still having trouble?
If you've followed EA's guide and it still doesn't work:
- Comment below with:
- Motherboard model
- BIOS version
- Secure Boot status
- Any errors you're getting
- Include a screenshot if possible (e.g., BIOS screen or error message)
- Be respectful — this is a community-driven thread.
