When you say you installed 8 on a secondary drive.... was that the only drive in the system when you did the install? What happened when you were running 8 and went into disk management?
When I did the install it was the only drive in the computer. I did this because last time I installed Windows 8 the secondary drive ended up cannibalizing the primary Windows 7 drive.
When I go to disk management in Windows 8 the Windows 7 drive does not appear. I scanned for changes and it still does not appear.
