You bought the wrong version, you bought an upgrade version which requires you to have an older version of windows to upgrade to win 8. It was not meant to be installed on a new system with no OS. You need something like an OEM system builders version of windows which costs more than 25. http://uk.pcpartpicker.com/part/microsoft-os-fqc05955
