Hi guys, I hope you can help me out with this one. I installed XP in my PC (Quad core 2 @2.66 ghz. 4 Gb RAM, two SATA HD 500gb and with two partitions each one <one for xp, one for Vista, ,one for W7 and one for files at least for now>, Dell mobo), then I installed Vista 64 bit, and recently installed Windows 7 64 bit, they are all working perfectly. Now, I've doing some research on how to quad boot, adding Mac OS X to the mix. Is this something that can even be done? if so where can I find a decent guide on how to do it?. Or can you guys please guide on how to use easyBCD to do it. Thanks for any feedback. I appreciate it.
