Problems with Chamelon, can only boot using DVD

[fowie]

I installed Hazard's snow leopard client-server onto my Gigabyte GA-MA-790X motherboard with AMD Phenom II X3 720 processor. I've done it before and booting/chameleon worked fine, but I must have missed a step, or the gremlins are out in force today. If I try to boot from the HD, Chameleon seems to load fine (Using RC3) and lets me select a drive to boot, but if I boot, it takes a VERY long time, and finally comes up with dual blue screens, never showing me the desktop. Actually, the problem seems to get worse each time I try. The first time, it booted up to the desktop, but nothing worked. I could move the mouse, but couldn't click on anything. The second time, one of the two monitors showed the desktop, the other was blue screen. The third time, dual blue screens.

Here's the kicker. If I boot using the Hazard DVD and press F8, then choose to boot my hard disk instead of the install DVD, it all boots up fine. What am I doing wrong?
