Note: Older Macs using ATA type drives may require you to configure the new drive as 'slave' using the drive's jumper(s).

After you install the new hard drive, you will need to boot to your old hard drive. If you have an external enclosure for the old hard drive, you will plug that in via Firewire or USB, (Note: USB is only a bootable option on Intel Macs) then turn on your computer while holding down the Option key on your keyboard. This will give you a boot menu that looks like the picture to the left. Click on your old hard drive to start the booting process, and your Mac will start up normally after that.
