I have Time Capsule and everything is backed up on there. My data is on a separate USB HD + Drobo, but for now I need my iMac to boot but it won't. It won't even get into the Desktop. Any idea how I an restore it? all the guides online says double click the Install Icon this and that...I would if I can get into the Desktop ! It is just stuck on the Apple Logo screen with the spinny thing, that stops spinning!
