Ok here is my problem i now have Windows Vista and iAtkos installed on my laptop. Now before i installed iAtkos Vista ran fine, but now that its installed i can only run the mac software, when i try to boot from my hard drive with vista installed and my laptop just restarts, im not sure if its Chameleon or if iAtkos has done something but now i cant access Vista at all. Should i reinstall Vista or is there another solution.

My laptop is a Dell Studio 1555.

Try fixing this with creating Linux Live CD. Then use Gparted for making Vista partition active (bootable) and then try again. This helped to me many times...
