I am a new Mac user, but am sold for life! Cant figure out this boot thing though. I booted from a cd by holding 'c' on startup, decided not to install the software (never went past the cd boot screen) and then my mac wouldnt boot from anything but the cd.... ever.... I restarted holding every key combo imagineable and ended up wiping the drive and starting over... Dont want to make a habit of that! How do I boot from the HD after booting from a CD?
