Hi, Si I have my 2009 Macbook Pro OS X 10.5.8, to which I bought 10.6.3 Snow Leopard, and upgraded it 10.6.8. So now, I want to bootcamp Windows 10 on it, but it need to repartion it before, so I bought the hard drive 1to and did all on it... But : now my original Mac Os X Install DVD don't want to know anything and is ejected as soon as I put it in, and my Snow Leopard work like 1 time / 4, even if pushing C letter and restarting as fast as I can... So How Can I Format My Computer, Please? And something else : should I upgrade my Mac to Yosemite 10.10.3 once I have (somehow) reinstalled everythings? I know I want to install Windows 10 32 Bit once I'll have format the crap out of this thing, but after I'm not sure, I have 250 go and 4go Ram... So please if someone could please help me, I want to play Path Of Exile as soon as I can Thanks for helping!
