also, what are the tips you can share guys that i need to consider before starting my first Hackintosh, i'm really a beginner with this so it's really complicated for me at this point, but of course, i'm eager to learn..

and lastly, i have pre installed Windows 7 Ultimate 64 bit in one of my partition, a Vista Ultimate which i will remove in favor of OS X, and an Ubuntu on the other one. I want to preserve the Windows 7 ultimate, is it possible to install OS X without harming win 7? also, is it possible to use the boot manager/selector of windows to select between Windows 7 or OS X? Thanks again!
