This will be explored by using bootable media to compromise an operating system. 1 Forced Entry with Bootable Media The Ultimate Boot CD (UBCD) provides an extensive set of tools and operating systems that can be booted from external media. The UBCD is a completely separate operating system and runs independently of any hard drives. The UBCD file system is completely on the CD. Booting under UBCD, you can mount and modify the files on your original Linux/Windows drive.UBCD, you can mount and modify the files on your original Linux/Windows drive....
