ISO images
An ISO image must be converted into installation media stored on a
DVD or a USB flash drive. Instructions are provided on this page. Developer
tools are available for download from
Windows Dev
Center.
Important: If you decide to go back to your
previous operating system, you'll need to reinstall it from the recovery or
installation media that came with your PC, which is typically DVD media. If you
don’t have recovery media, you might be able to create it from a recovery
partition on your PC using software provided by your PC manufacturer. Check the
support section of your PC manufacturer’s website for more information. After
you install Windows 8, you won’t be able to
use the recovery partition on your PC to go back to your previous version of
Windows.

How to install Windows 8 Release Preview from an ISO image
The easiest way to convert an ISO file to a DVD in
Windows 7 is to use
Windows Disc Image
Burner. On a PC running
Windows XP or
Windows Vista, a third-party program is
required to convert an ISO file into installable media—and DVD burning software
often includes this capability. One option is the
USB/DVD download tool provided by the
Microsoft Store.
