PC gaming enthusiasts faced technical challenges accessing the Battlefield 6 beta due to a security error indicating that "Secure Boot is not enabled." Secure Boot is a feature in Windows 10 and 11 that ensures only safe software loads during startup, but enabling it requires navigating the BIOS menu, which can be complex and risky. EA's guidance on enabling Secure Boot led to further complications, including issues with disk partition compatibility that required converting from MBR to GPT. Additionally, EA's anti-cheat software, Javelin, necessitates Secure Boot for enhanced security against cheating, a trend also seen in other gaming companies' anti-cheat systems. EA reported blocking over 330,000 cheat attempts during the beta weekend, though concerns about the effectiveness of these measures remain.
