How to Boot to Optical Drive on a MacBook
If a booting problem occurs with your MacBook, or if the computer freezes on you often, one fix is to boot from a drive other than your main hard drive. If you don't have an external hard drive, you can boot to an optical drive on a MacBook quite easily. One advantage to booting from an optical drive is that you can repair any disc problems on your MacBook from there, and then reboot on your main drive. Another is that the optical drive is already attached to your MacBook and requires only a CD or DVD with a bootable copy of a MacBook OS on it in order for it to work.

Tips & Warnings
MacBook Restore DVDs come with every MacBook, but you can use a back up copy of the MacBook Restore DVD instead, if you have one.
The CD or DVD you use must have proper booting software installed on it--meaning a Mac operating system compatible with a MacBook. Such discs include the Mac OS X install discs that came with your MacBook or the Mac repair discs that come with the Apple Care Protection Plan. iMac restore DVDs will not work.
