While originally distributed as a bootable CD-ROM, modern versions are typically deployed via USB drives. This paper examines the technical process of booting from Hiren’s Boot CD, the underlying system architecture (DOS, Linux, and Windows PE), and its primary applications in system diagnostics, password recovery, malware removal, and data salvage.
