It`s amazing how your story keeps changing, first the hard drive was dbanned, then it wasn`t done yet. You don`t have a COA, then you think you do. What gives here. Either do it the way you want or take our advice and burn the Windows 7 iso to dvd and install windows and sell the pc. Why would you put a W8 upgrade on it
Just put the original version of windows that came with the pc back on it and be done with it already, you are being so stubborn and Greg has been so patient with you. Come on Man
To answer your question, Yes, windows will install on a dbanned hard drive.
Also, start reading the tutorials you have been given.
