Did you burn it on a DVD-R or DVD+R?

How did you burn the .ISO file? You don't want to burn the file to a DVD. You want to use the file to create a DVD from the .ISO image.Scroll down to step 2 in the following link:http://www.microsoft.com/windows/windows-7/beta-installation-instructions.aspxHere's some step by step instuctions:http://mintywhite.com/tech/windows-7/burn-the-windows-7-iso-to-a-dvd-how-to/Kerry Brown MS-MVP - Windows Desktop Experience

But for me it didn't work with a DVD-R.
