OK, you better go the clone route. Here are a few suggestions. the first link (Easeus/Todo) may do the trick. I have never used it myself because I have Norton Ghost (which unfortunately is not free). But Easeus has a good reputation. Sone of the others may do it too.
But in any case, if you want to clone to E, disconnect C whilst you are doing it. And if you want to keep the clone on E, you need a seperate partiton for it - but I am not 100% sure whether that works because I always go via an external disk. You may want to get one - they cost $50 to $80. Deals2buy: Storage Devices deals
And when you are all done, I suggest to make a seperate partition for your data. Here is a little video I made on how to do that. You best do the partitioning before you install the system. That way you have more freedom regarding sizing. Once you have the system installed, you may be limited with shrinking the new C.
PS: I just saw the previous poster also recommends a seperate data partition. And his way via Gparted may be good too if you don't mind doing the startup repair. I dread this, but that may be just me. LOL
