How to remove Chameleon completely?

Hi. Skip to last line to see main question.
I have some problems with my bootloader, Chimera whom I was installed from MultiBeast. It doesn't show theme on boot and it doesn't select Lion partition as default one. Selector stays on Windows partition but it doesn't start automatically. If I click enter without clicking up/down buttons, it gives an error about mach_kernel. If I press up & down then click enter, it loads Windows.
Other problem is an app about bootloader gives me "boot cannot be read it may be damaged or has root:wheel permissions" error. I tried to fix permissions many times. But nothing changed.
So how can I remove Chameleon completely? Thanks!

SOLVED.

I know I'm bringing out an old thread but I didn't want to start a new one.

Basically, I've been having issues with Chameleon/Chimera and was wondering how to completely remove it for a fresh install

I've wiped my OSX install HD and it still seems to show up
