The ISO file, also called disc image, is a copy of an entire data CD or DVD. After making a CBackup bootable ISO file, you will first need to burn the ISO file to a CD/DVD or USB flash drive before you can use it. This article will show you how to burn ISO files to USB flash drive and CD/DVD with various burning software.

Before you do

  • Download a CD, DVD, or Blu-Ray burning software (here we take UltraISO, BurnAware, and Free ISO Burner for demonstration).
  • Prepare a USB flash drive or a recordable CD, DVD, Blu-Ray disc.
  • Make sure your computer has a CD, DVD, or Blu-Ray burner.
