Hey, So I really like Mac OS X over Windows products. So Me and my brother share a PC. I like Mac OS X/Snow Leopard and he likes Windows 7. So I told him we can dual boot and make Windows 7 as the main OS. So we agree on that. But there's one problem. I don't know if I have the correct specs and I don't know how to do this... My specifications are: http://www.emachines.com/products/products.html?prod=ET1161-05. It's a Pc. So help me out here :d Thanks.
