Microsoft Secure Boot is a component of Microsoft’s Windows 8 extended with more security advancement to Windows 10 & 11 operating system that relies on the UEFI specification’s secure boot functionality to help prevent malicious software applications and “unauthorized” operating systems from loading during the Computer start-up process.

Although having it activated will make it difficult to install Linux or other operating systems on the computer, the secure boot functionality is primarily designed to protect users from rootkits and other low-level malware attacks by blocking unauthorized activities and drivers from being loaded during the start-up process. Modern computers come with the feature enabled. This is a platform feature in UEFI, which replaces the traditional PC BIOS.
