BO7, referring to Call of Duty: Black Ops 7, requires Secure Boot as part of its enhanced security protocols to prevent cheating. Secure Boot is a security standard in modern PCs that ensures only trusted software is loaded during system startup. To enable Secure Boot for BO7 (and TPM 2.0), users need to enter their computer's BIOS or UEFI settings, typically by restarting the PC and pressing a key such as DEL, F2, F10, or ESC during boot. In the BIOS/UEFI, Secure Boot can usually be found under the Security, Boot, or Authentication tab and must be enabled. It is important that the BIOS Boot Mode is set to UEFI, not Legacy, and that the disk partition style is GPT instead of MBR. Secure Boot may be greyed out unless UEFI mode is enabled and other conditions are met. After enabling, saving the changes and rebooting confirms it is active when checked in the System Information window under "Secure Boot State" (which should say On) and "BIOS Mode" (which should say UEFI). This setup is mandatory to access BO7 beta on Windows PCs because it helps protect against cheats by ensuring only trusted software loads during startup.
If needed, BIOS conversion from Legacy to UEFI and disk partition conversion to GPT may be required to enable Secure Boot. Detailed instructions vary by motherboard manufacturer, so consulting official manuals or support websites is recommended.
In summary, BO7 Secure Boot means enabling a PC startup security feature in BIOS that validates software authenticity at boot to comply with the game's anti-cheat requirements.
