If I go through the process described here and nothing is in the disc drive it will default to the HDD right? I'm in the process of installing Lion, I'm on Lion, you can see why here: http://forums.macrumors.com/showthread.php?t=1321728 The process I am describing is referred to here: http://kb.iu.edu/data/ages.html As: I attempted to press c, but it did not work. Perhaps I should try the second option instead? I'm going to give it a go and be back. Please leave feedback if at all possible, any and all help is definitely appreciated. I'm kind of a noob on Macs and I need a fresh install. ---------- Option key seems to do nothing as well. Any ideas? Usually on windows it will just auto-detect the boot cd and initiate the install or maintenance sequence.
