I went to the windows download site to download windows 7 RC... they say to do a clean install on a test machine but the file they downloaded is an iso file (2.36 GB). Where do I go from here? How do I make the iso file turn into win 7 install. If I have to put it on a cd-I can burn in to a cd on another computer... but how do I make the cd bootable and install? If you can help, thanks in advance
