Chimera doesnt boot into system on P8P67

I installed Lion on my dad's PC and now i have a few problems:

Although i can boot into Lion fine using the Rboot disk. When i try to boot using chimera i get kernal panics. One other issue i noticed was that, when it boots into Lion, it is not very stable and something so small like inserting a USB stick brings me to a kernal panic screen where i can only restart and it's my only option. Any ideas. Thanks.

System specs:
Mobo: P8P67
12gb Ram
1tb HDD
Nvidia GT220 GPU
Core i7 2600k

Try booting into lion with rBoot. once in lion download Chameleon 1730 boot loader from osx86.net in the boot loader section and install it. I have had issues which newest chimera with waiting for root device and cpu kernel panics. Chameleon 1730 boots right in no problem.
