today my new Kingston SSD arrived and I want to install a fresh copy of Windows 7 on it!Problem is my Internet sucks and I also have a lot of files that I don't wanna lose such as sony vegas projects and stuff! Question is how can I uninstall windows 7 of my HDD and turn it into an "external hard drive" type of thing so I don't lose any of my files 
Thanks in advance
Edit: I just tried installing windows 7 on my SSD and as I boot my windows 7 setup it shows "No drives were found. mass media storage something"
Can you help me?
