ISO Creator has included a Bootable option which when selected will automatically write a boot image to the CD. An ISO file is a digital "photograph" of another disk; these files encode the complete geometry of the original disk. You can create ISO versions of your favorite applications and games to have great backup copies in the event a disk is lost or damaged. ISO Creator has an easy to handle graphical interface and is ideal for any computer user regardless of their experience. A bootable CD-Rom is a CD from which you boot the PC. This means putting the CD in your CD-Rom drive and power-on or reboot your system. The PC will load a boot image from the CD-ROM and control is given to this boot image. ISO Creator permits you to take advantage of using the internal boot image as well as choosing your own, which is ideal for making the CD bootable after the ISO has been created and then burnt back to CD. It has advanced options and has the most optimized setting to load as default, which permits you to get the job in hand done more quickly.
