Is Hackintosh Snow Leopard compatible with almost all intel/amd processors but it comes down to if you have a sata/ahci supported harddrive? Also, if someone happens to only have one harddrive, how easy is it to patition the harddrive and use easy bcd to boot both windows and snow leopard?

I never got partition to work before, that is why my setup is on two different harddrives on my computer. I have Windows 7 on one harddrive and Snow Leopard on the other. Can Windows 7 and Snow Leopard work on the same harddrive with partitions or does that create too many problems?
