What is Secure Boot and its Purpose?

Secure Boot is a feature that ensures your computer boots using only software that is trusted by the PC manufacturer.

Attaching and inserting Secure Boot keys on your ASRock B550M PRO/CB4 motherboard guarantees that the system boots with only trusted software and operating systems, reducing the risk of malware or unauthorized access. Secure Boot checks every piece of firmware or software during startup, promoting a more robust security posture for your computer.
