I've downloaded the iso on 3 different CDs using different burners to burn them. All the CDs load during start up but after choosing to hit enter, the screen goes blank and does not come back. I've also tried using a USB but the computer will not register the USB. I was wondering if anyone else has had the some problem and has a solution. I am using a Toshiba Satellite with windows 7 home premium. Any help or advice will be appreciated. Thanks in advance.
