When Windows 10 comes out, I know it's not for a while, I plan on buying an SSD and getting Windows 10. I currently have Windows 7 on my only HDD. I might buy another 1 TB HDD between now and then but I am not sure. So what I am wondering is if I want to put Windows 10 on my new SSD, would I have to uninstall Windows 7. And if I do, how would I do it. I know how to install Windows, but I am not sure if the process would be any different if I didn't uninstall Windows 7.
