Put your install DVD into the optical drive and reboot. As soon as you hear the boot chime, hold down the 'c'key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the install DVD in the optical drive. Once it has finished booting and you are at the Install screen launch Disk Utility from the Utilities menu. Is your Hard Drive in the list on the left?
Click on the drive and select the Erase tab. Set the format value to Mac OS Extended (Journaled) and click the Erase button. After that has finished select the Partition tab. Type in a Name for your hard drive and select how many partitions you want from the Volume Scheme. The usual setting is one partition.

Your drive should now be blank. You can now install a new Operating System.
