hey all, i need some help! last night i installed some recent updates on my girlfriend's macbook, and this morning it won't boot - it gives me a blue screen with the spinning wheel at the bottom, and stays there. i've given it ove an hour and it's still stuck. the problem is, her optical drive is not working, so i can't boot from the OSX dvd and restore from time machine. what are my options? here is what i have at my disposal: the frozen macbook, the external hard drive with her (and my) time machines backups, my macbook (with a working optical drive), a 1gb usb flash drive, and the internet. what can i do? please help me!
