How to Make a Bootable ISO

Certain applications must burn onto a bootable CD to run themselves before the system begins to initiate. When an operating system has a problem that requires troubleshooting without running the actual system itself, the tools that troubleshoot the system must run before the system itself so as not to touch any data that might be in use. To make a bootable ISO, you must write some data to give instructions to the computer on how to proceed with operations without booting from the hard disk.
