I have an old hard drive from my old laptop, I built a new computer and got a new hard drive and new version of win7 with it. BUT i want to use my old hard as it has all my stuff on it, the issue is i don't know how to uninstall the windows on it/keep all my files and have windows uninstalled.(i dont have a hard drive to perfourm a back up to) How would i go about uninstalling windows and keeping my files intact?
