I have 2 harddrive, one with windows 7 installed and the other one with windows 8.1. Windows 7 acted as my primary and default boot hdd/os. However, the primary hdd is failing so I decided to remove it but since then I can't boot into windows 8.1 when only 1 hdd is connected. I have changed bios boot priority and default boot os to win 8 but it appears that whenever the primary hdd is removed, it won't boot into win8 but giving me a black screen with blinking underscore.
Using win 8.1 installation cd helps nothing (somehow I can't boot from the disc)
