Mount an ISO onto a virtual drive:

  1. In order to mount the ISO on a Windows computer, you will need to use a third party ISO mounting application. Some options include:
  2. Review the instructions or Read Me files for these tools for directions on how to install the software and mount an ISO.
  3. Mac OSX will automatically mount an ISO by double-clicking the ISO file itself.
  4. Once the ISO is mounted, you can browse through all the files contained within the ISO to begin your software installation.

  2. When burning your disc, be sure to select the option to create disc from image, or burn image. Do not simply create a data disc, which just copies files and folders to disc.

    • Locate the ISO file that you want to create a CD/DVD from.
    • Right-click on the ISO file and select Burn disc image.
    • Select your Disc burner on the next screen and click Burn.
  4. Mac OS X can also create install discs without any third party tools:

    • Under the Images menu, select Burn.
    • Select the ISO file that you want to burn.
    • Make any changes to the options, and click Burn.
  5. Once the CD/DVD is created, you can use the disc in any computer with a CD/DVD drive and install software directly from the disc.

Extract the ISO contents:
