You can't just move your C: drive, unless you have an Acronis image or similar.
I would disconnect your existing drive and connect up the new one. Put in your OS disk and follow the prompts to do a fresh install on the new drive. Keep going back to Windows Updates until you have all the relevant updates installed. Your new drive will now become your C: drive.
Reconnect your old drive again. It will now have a new drive#, and you will be able to access and transfer any documents or data files you wish to. You should be able to run any installed programs from your old drive, but I would be inclined to install the programs fresh on your new drive.
To avoid any dual booting conflict, I would remove as much of WINDOWS from the old drive as possible.
Let us know how you get on. Good luck.
