How to install the Windows Developer Preview from an ISO image

The Windows Developer Preview is delivered as an .iso image that must be converted into installation media stored on a DVD or a USB flash drive. On Windows 7, the easiest way to convert this file is to use Windows Disc Image Burner. On Windows XP and Windows Vista, a third-party program is required to convert an .iso file into installable media—and DVD burning software often includes this capability.

Note: The .iso file that contains the developer tools requires a large capacity DVD called a DVD-9, as well as a DVD burner that can handle dual-layer (DL) DVDs. Most modern burners should be able to handle this format.
