Some Call of Duty players on Steam are facing frustration due to the game’s requirement that Secure Boot be enabled in their PC BIOS. This security feature, intended to protect system integrity, requires players to modify BIOS settings—a process many find complex and risky. For less technical players, this creates a barrier to entry that could reduce the active player base or increase support requests. Players should be aware that this hardware security prerequisite may affect their ability to launch or play the game smoothly as of October 2026.

  • Secure Boot must be enabled in BIOS to run Call of Duty on PC.
  • Some players hesitate to change BIOS settings due to complexity and risk.
