Well ive had my macbook for a few days now, and thought id install bootcamp to test windows out on my beautiful mac. Having set everything up and had a quick blast on halflife, i obviously wanted to go back to the more homely os x. DISASTER! I cant work out how to change back. As soon as my computer powers on, and the dirty-creme screen appears i hold both option keys (the one with the apple logo on, right) down, but no joy. Has anyone else had similar problems/experiences, or cna anyone offer any help? Am i just being really thick?
