Installing windows 7 on top af existing windows 7
2 years ago I bought a laptop with preinstalled Windows 7 and a D: partition with installation files.
Now I wanted to 'format' or recover my HD to remove all kind of dirt etc., but I cannot get recovery files for it (and did not make any, when I bought it) - it's a very long story.
So I have bought a NEW Windows 7.
BUT now I am not sure, what happens when I try to install that on top of the existing.
Would it not best to make a good old formatting of the HD first, and how do I do that?
