When you installed Win8 to the SSD, was the HDD connected to the system?
No it was not.
I tried both methods, first time HDD was connected to the system and the new OS would not start at all during first boot.
Second time, I removed the old HDD then installed Win 8 on SSD. Was able to successfully boot into SSD with no issues. It only fails to boot again once I reconnect the old HDD.
