Is it possible to have Vista as the only OS on a C2D iMac? If it is, I have 2 questions: 1.How do I install it? Would it work this way Start up with the Mac OSX CD, run disk utility and format drive as MS DOS (or something like that). Then put Vista CD in it, restart and boot from cd and install vista. 2.What about firmware and SMC updates? If apple releases firmware updates I wont be able to install them. My question is, are firmware or SMC updates any good for me if I would only use vista? Would it be as useless as a Mac OSX 10.4 update (Because I wont use it) or is it different? If it is different and important to update the firmware would you recommend to have a small OSX partition only with OSX installed to install firmware updates? The reason I want to do this is I just love Vista never installed it before and if I wont do it soon I will get insane. I am waiting and looking all day for a leaked RTM version to check Vista out. Hopefully it will be out today or on Monday as they say. And if I will like Vista still until January I will buy the retail version.
