I've tried everything I can find. Not booting in verbose leads to the loading apple grey screen, and after about 5 minutes, a grey circle with a line through it inside the apple (The universal 'No' symbol)

My specs are:
250gb hdd 5400rpm
ATI Radeon HD 4650m
Intel i7 720qm
4 gigs of ram
Screen: 1600x900

OS: Kalway OSX 10.5

Kalway runs fine, it's what I used to write the USB drive with the osx 10.6 instal disc

Any advice? Anybody have success hackintosh-ing the Studio 1747?
