Convert IMG to ISO on Windows 7

In order to mount an image file on VirtualBox, I needed to convert an IMG image file into an ISO format (VirtualBox does not support mounting IMG files). There seem to be a myriad of applications available for this purpose; many of them commercial or at least shareware.

With OSFMount I found a free and handy tool for this purpose. Download and install the software, then mount the IMG file you need to convert.

Right click the mounted drive and select “Save to image file…”.

Choose “RAW CD Image (*.iso)” and Voilà! You have an ISO file, which can be mounted by VirtualBox.

  1. No longer. The Supported File Extensions table at the website shows that it does not support writing .ISO files.

    1. Thank you for your comment!

      Did you test this and it didn’t work for you? Yes, on the website they say they don’t support ‘Writing’ to ISO images but I think you can still create an image, since there is a green tick in the column ‘Convert to Image file’.
