How to burn an .iso image onto a CD/DVD-ROM | Seagate UK (2024)

Just like the old boot floppy diskettes, CD or DVD-ROM discs can boot to a DOS or other operating systems. Just copying files to a CD will not work because the CD will need a master boot record and other hidden Startup operating system files. Instead, the preferred method is to create a single file, an image of a bootable CD, called an ISO image. Most CD-ROM burning applications recognize this type of image file. Once the ISO file is burned as an image, then the new CD is a clone of the original and bootable. Besides the bootable OS, the CD will also hold the various software applications like many Seagate utilities that are downloadable in .iso image format.

This document will cover How to use a downloaded ISO image and methods for rendering an .iso file ready to use.

Hardware Prerequisite: An internal or external CD-ROM burner is required for burning the ISO image to a blank CD.
