Hi,
Thanks that worked, quickly held down key "1" after selecting my USB boot device and in the Chameleon bootloader. Think I'll stay with Chameleon then, always used it fine before on my older hackintosh/Windows system on Snow Leopard.
Installer loaded fine too, only have snow problem over DVI via KVM switch, think had it before, does OS X enabled HDCP that my KVM may not support? It works fine normally if I connect to my monitor's HDMI port instead.
