I've been browsing the Internet for a while about this now and can't find any solution.

The Sata connector of my old HDD broke and now I had to duct tape the cable into the socket. It works as normal but eventually the duct tape loses its stickyness and falls off like every third day. I want to buy a new SSHD and copy my files 1:1, including Windows 7.
The point is, that I can't find my Windows CD anymore and don't want to buy a new one for 80€+, so that makes me unable to get a new license and I rely on my old data.
Is there any way of "cloning" my whole HDD to a new one and that windows works when I unplug the old HDD?

tl;dr : HDD is close to death. Want to copy it 1:1 to a new one. How should I do this the best way?
