hi, i'm in a bind and don't have much time. our flight leaves the country in 14 hours so, we have a macbook and a mac mini. i just replaced the stock macbook hdd with a 500gb WD drive no problem. also, i have a time machine backup on an external hdd ready. the problem is i cannot find my OS X dvd anywhere. however, i did find my OSX DVD for my mac mini. still, when i turn on the macbook all i see is a folder blinking with a question mark in it. doesn't seem to work, but i have almost zero mac savvy. how can i get my OS installed tonight?
