To create a bootable ISO image is simple if using ImgBurn. The advantage of using ImgBurn is that is compatible with Windows 7 through Windows 10 I’ve tested it myself. So if you want to create create a Windows ISO image out of a Windows disc just follow this tutorial. I’ll be using Windows 8.1 for my tutorial.
1. Download install and run ImgBurn.
2. Select Create image file from disc.
3. Now select the Source drive from the drop down menu, select the destination location of the ISO (Desktop) by clicking on the folder icon, and finally click on the disc to image icon to create the ISO image.
Done!! Once finished it will play a little jingle letting you know that the Windows ISO image was created.
