Hazard also reboots instantly on my AMD pc. What I did was create two MBR/HFS+ partitions. On the first one I installed iDeneb 10.5.7. From within iDeneb I've installed Hazard onto the second partition. The iDeneb partition is now being used for Windows 7.

To start the install in iDeneb, open Terminal and open Volumes/Hazard_install_dvd_name/System/Installation/Packages/OSInstall.mpkg if I remember correctly.
