Well, I've been trying to get that Win7 work properly for 2 days and I'm really tried of this crap. Have no empty dvd to burn the lion as image, have one double-layer dvd but so-called superdrive can't calibrate the power of its laser to burn that dvd. And since I have an limited internet connection with quota, I can't download the drivers bu using bootcamp assistant. The only option for me to get them from lion's dmg file. I hoped if I copy the content of dmg file into a USB disk, that would work as if it's an DVD. However didn't work. Now I want to directly extract those drivers from Lion dmg file. However there is no such instruction on the web for lion, there are some for snow leopard but they didn't work for me, suppose Lion has a different content. As the case like that, is there anyone who can come up with a solution ?
