I installed iATKOS 7 on my HP Pavillion dv7-2177

Intel Core 2 Duo Processor P7750 2.26GHz
4096MB DDR2 System Memory
500GB (5400RPM) Hard Drive (SATA) with 190GB for OSx86
ATI Mobility Radeon HD 4650

The install was successful, and I used the Chameleon2 loader, which worked just fine. I booted up and got to the apple screen with the spinning wheel, then the screen went black and some dance music started playing. The screen is still black and the music stopped and thats all I have.
