i am using my old windows 7 pc and upgrading it with a new processor and all that. Basically I am building my own pc using the old one. The problem is the cPu I am getting does not support Windows 7 but I am planing on upgrading to Windows 10 once I get the computer working I don't know how I would do this if the cpu will not work with Windows 7. Just for clarification I do not have any other processor to use for the installation of Windows 10
