I'll risk the flames, and say go back to basics.
 
Make sure of the drive cabling and jumpers. 

I was reloading a home-grown nas the other day and the cable and jumpers gave me a bugger of a time. 7.2 would start to boot and then just hang. I unplugged everything except the harddrive on the primary and the optical drive on the secondary. After the OS was loaded, I was able move everything where I wanted.
