I have a laptop with Windows 7 installed and I just installed Win 7 Home Premium on it. I thought that would uninstall the original Win 7 but i dont think it did. Now everytime I start up my laptop, i get a black screen asking which Windows to open and the 2 options both say Windows 7. It also says that I have 30 seconds or else the highlighted choice will be started. The first and highlighted choice is the new Windows, the one i want. How do i get rid of the old windows and the black screen?
