HawesDoesIt :
1. Yeah.
2. I was planning on a fresh install.
3. I just installed it off a USB Drive and used my old Win 7 CD key and it verified it.
Assuming it is activated on the current system...verify this...then a clean install is no problem.
Create your own Win 10 DVD or USB here:

Disconnect all other drives
Boot from that DVD or USB you create
Install on the new drive.
When it asks for the license key, select "I don't have a product ID"
When it goes online later, it will activate itself.
