In a beginnin i had windows vista home premium, but my university gave to me the windows 7 professional. I believed that the one that was coming in the dvd would give you the option to choose between 32 and 64 versions, but it doesn't and already I was too much late to stop the installation, this way that I installed the windows 7 of 32 bits. Now then, I have already a dvd with of 64, introduce it and it says to me that with this version of windows cannot be installed, that i start the computer with the dvd and that i choose the option to initiate the CD before entering to windows to do an installation of this one. But it does not appear at all on having started. so, How do I do it?
