I used Nawcom, which requires a retail DVD. You use the nawcom to get the retail to install. See the nawcom site for details. #####, which does the same thing, would NOT work for me. If you don't know what kexts are, you likely need to step away from the machine. Bios needs to be set to ACHI manual.
When i tried nawcom after i insert the retail dvd and after the initial boot, the system would auto reboot. AHCI was set to manual in the bios. Did you use any other settings? System is r530 core i3
