                'The MBR is the section of disk that is first loaded after '
                'completing hardware initialization by the BIOS. It is the '
                'location of the boot loader. An adversary who has raw access '
                'to the boot drive may overwrite this area, diverting '
                'execution during startup from the normal boot loader to '

                'Similar to the case of MBR, an adversary who has raw access '
                'to the boot drive may overwrite the VBR to divert execution '
