I have had a Toshiba laptop with 32bit windows 7 basic and have got a wndows 732bit Professionai which I bought fo my desktop but never used, can I install it over the existing
32bit windows 7 ar would I have to do a format of the hard disk.

Or is it possible to intall with the supplied disk and delete the win 7 basic when it is installed and then install the profesional version.

I hope you can understand me.:(
