no the original will not boot, you will have to use a bootloader, usually Chameleon RC3 will do. You grab the script from the link i posted above, install it on an 8GB usb stick and than restore the snowleopard image on it. reboot and you should be good to go. You will have to make your install partition or disk GUID to install snow leo. Just dont forget to install NullCPUPowerManagement and NVEnabler in /Extra.

cheers
