why you didn't make fresh vanilla install from retail dvd?
i have same laptop.
i have intall 10.6.3 retail dvd, compo upadate 10.6.7. install chameleon from multibeast
and all works perfect.


if you want to make install with iatkos try to not check bootloader. then with iboot boot your system,make update and then intall chameleon from multibeast. i hope that works
