An ISO image (International Organization for Standardization) is an archive file (also known as a disc image) of an optical disc, composed of the data contents of every written sector of an optical disc, including the optical disc file system. In most cases ISO Images are used to contain the true digital copy of the original disk. So, if you’ve downloaded an ISO image, just keep in mind that it is not an ordinary data CD/DVD image. Especially, in case of Operating Systems, these ISO Images contain files that make CDs/DVDs bootable, therefore, you need a special software to write them on CD / DVD and then install them.
How to mount an ISO file on Windows 7
If you need to see the contents of an ISO file that you just downloaded, then you will have to mount it in your computer. Mounting an ISO image file is similar to inserting a CD / DVD ROM in your CD /DVD Drive, the only difference is that this would be done virtually. Mounting an ISO file has a lot of benefits. Before burning it on to a CD or a DVD, you’re able to check the contents and verify if everything is just as you want. Or, if you want to install a software or a video game but don’t want to burn the ISO image on a CD or DVD. This would come in handy if you don’t have a CD / DVD Drive altogether in your PC or netbook. Windows 7 doesn’t give native support for ISO files so you have to use third party tools.
Using Virtual Clone and Magic Disk
- Virtual Clone Drive lets you mount almost all kinds of image files be it ISO, UDF, BIN or CCD.Make sure that you have Administrative privileges on your computer before you continue. Download the utility and install it. Through installation steps, it will ask you for file association and then it will install the Drive Software (Application Driver). Now just double click on your image file to mount it.
- Magic Disk is a similar program but it also gives you the option to set a number of multiple virtual drives and also change the drive letter of your existing virtual drive.
Remember that all the ISO editing / manipulating applications like Magic ISO, PowerISO and UltraISO have built-in capabilities to create virtual drives and mount ISO files in them.

How to install an ISO file / image without burning it on a CD/ DVD
Extract the ISO Image
Well, you can either mount them. Or you can extract them. As stated in the introduction, ISO files are archives so almost any archive extraction application like WinZip , WinRAR and 7Zip can extract the contents of the file. 7Zip is the recommended software here as not only it is free but it also supports almost all kinds of compression formats. It has also the support for checking an archive for malware or virus before extracting it. Just keep in mind that once you have extracted the ISO image file, you cannot get back the same image file by compressing the data again. So, be careful before deleting the original ISO image file.
Write it on a USB Flash Drive
