ezueckg Posted September 13, 2012 Share Posted September 13, 2012 Hi, I've been trying to install Mountain Lion but don't know how do it properly. My motherboard has no AHCI option but has RAID. I've heard of people installing on an external USB HDD because of this but I have also heard it is possible to install in my main HDD with something called ATAPortInjector. I have no idea how to do this but I have a VM through which I can create a Mountain Lion USB (don't know if I should use ###### or what else). How do I install it? What would I have to do to get a dual boot with Windows 7? My specs: Dell XPS Studio 8000 4GB DDR3 1333 RAM HD 5770 Intel i5 750 Thanks! Link to comment Share on other sites More sharing options...
