I was trying to dual boot Windows 8 with Windows 7. Windows 7 is already installed and I used Windows 8 installation dvd. I remember I had selected the correct location to install this operating system. I am not able to figure out what really happened. I am not able to get Windows 7 back. The system just boot in Windows 8 and that too is crashing with blue-screen. This means I am completely screwed up. Is there a way through which I can restore the old state of my pc.
