I probably just need some very basic advice, so I'm apologising in advance in case I'm being too stupid for words!!! 

Having read through some of the posts on here, and having tried repeatedly to get my new copy of Vista 64 to load, I'm now at a loss. I bought a used PC with Vista 32 Ultimate already loaded (but not activated) and have now rebuilt the PC in a new case and I want to load the Vista 64 I bought from Overclockers. It will not boot up automatically and even going into the setup and setting "Boot from" to CD Rom it still will not load. Nada , zilch , nuffink. Simply goes straight into the 32 Ultimate. Time after time!
Am I doing something wrong?
