Abstract
A system detects deviation from a computer operating system boot and operating system load. The system identifies approved operating system boot modules, approved operating system load modules, essential operating system boot components, and essential operating system configuration information, which are then hashed to create an operating system boot profile. The operating system boot modules and the operating system load modules are then executed to start the operating system. The operating system boot profile is used to verify that that there has not be any deviation from the start of the operating system.
