I would like to know how this works. If you back-up your O/S and all the files and the computer crashes how do you reinstate everything. I have always wondered this and thought I would ask the question, especially if you use Paragon or something similar and yet you can't open it to restore, because your computer doesn't boot.
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.
