How to Boot From a CD Through Command Prompt DOS

Although outdated when compared to operating systems utilizing graphical interfaces, DOS is still functional enough to perform all required computing tasks, including booting programs from a CD. Although you will have to know which file on the CD is the bootable file in order to execute the appropriate command-line argument, this is not an issue since bootable files typically end in the "EXE" file extension.
