An ISO file, with the extension .iso, is an image file of a CD/DVD-ROM that is created from a CD-ROM using burning software or a CD-ROM imaging tool. CDs or DVDs can be bootable to DOS or other operating systems. Many users prefer to install or reinstall the Windows operating system from an installation disc created using an ISO file.

After you download the Windows 11 ISO file or the Windows 10 ISO image, you can burn it and create bootable installation media, either a DVD or a USB flash drive, or a virtual machine (for the .ISO file) to install the operating system.

Burning an ISO to a DVD isn't as simple as copying the file to the disc, because DVDs require a boot sector and other hidden operating system files to start up. Let's learn how to burn an ISO image to a blank DVD. We'll use the Windows 10 ISO as our example.
