I've got a HP Pavilion p6360uk, I've used OSx86 on my netbook and some previous PC's.
This however is beginning to get annoying, I've tried: iATKOS 10.5.7, iPC 10.5.6 Final, Snow Leopard, iATKOS v5i, Kalyway 10.5.2, iDeneb 1.4 10.5.6 and iPortable Snow Leopard.

The only one that even got to the installer was iDeneb 1.4, all the others just start and get to "Starting Darwin/x86" and then reboot (it goes really quick) and I've tried all the -x -f -v and cpus=1 and whatever else I could find on the issue. The iDeneb installed and on bootup it gets to the same "Starting Darwin/x86" and reboots like the other installers do, I have tried different Kernels, all kinds of different customization options but still no luck.

Okay, PC Specs;

If you need any more info just ask.
Thanks, I just hope someone replies.
