Users who recently got Windows 7 Beta 1 from MSDN site or the leaked image from torrent sites probably realized that they can only install the Ultimate edition of Windows 7. But other three versions still exist (Home Pre., Home Basic and Business). Not everyone needs all the features of the Ultimate edition, thats why I am showing you how to bypass this limit.
All you have to do is delete a file named ei.cfg in the installing image (\sources\ei.cfg), and you will be able to choose between the 4 editions of Windows 7 during setup.
You are recommanded to extract the file to hard drive then make the change, and install Windows 7 on hard disk. But if you want to burn it to a dvd and do a DOS install, you have to rebuild the image after making the change then burn and install.
