Abstract
A method of securely booting a computer system includes executing program code of at least one boot loader to load a kernel; verifying, during loading of the kernel, the program code of the boot loader after at least a part of the program code of the boot loader has been executed; and interrupting the booting if a result of the verifying of the program code of the boot loader indicates a manipulation of the program code of the boot loader.
