I downloaded the WIN 7 64bit .iso file from microsoft and burned it to a dvd. I have a Dell E6400 with a wiped hard drive that I want to load Windows 7 onto. I put the burned dvd into the e6400 and change the boot order to CD/DVD drive but it doesn't run. Is that burned DVD not bootable? I downloaded MagicDisk but I'm clueless, I want to be able to put the DVD into the e6400 and it self load the paid for copy of windows 7. Thanks in advance.
