This article explains how to burn an ISO file to a DVD, CD, or BD in Windows 11, Windows 10, and older versions of Windows. The process is different from copying a file to a disc. You need to burn an ISO file to a disc (or a USB drive) in order to use it properly on that device.
Windows 11, Windows 10, Windows 8, and Windows 7 include a built-in ISO burner tool that makes this easy. This process works for DVDs, CDs, or BDs.
Make sure you have a blank disc in your disc drive.
As long as your optical drive supports it, this disc can be a blank DVD, CD or BD.
