Not sure if this is the right place for this but I am new here. So I have built my hackintosh and I have three hard drives one with windows 8, one with OSX 10.8 and one with UNBUNTU. This was working fine until I realised I had a 32bit installation of windows, so I unplugged the OSX and unbuntu and attempted to install 63bit windows. The installation was unable to complete and after a few tries I gave up, plugged in the other two drives but now the chimera boot loader doesn't come up and it just boots straight to windows (it should boot straight to OSX). Any ideas why this happened? and how to correct it?

Thanks, Tom
