Place a blank DVD into the drive. If you are running Windows 7 or beyond, you are able to natively burn DVDs from an ISO. If you are running a version of Windows before 7, you can also use ImgBurn, Nero or other burning software to burn an ISO to a DVD.

Locate the ISO file. Use Windows Explorer to locate the ISO on your computer. Either using the Start Menu then click Computer or click on the folder icon on the taskbar.[3]
