How do I do this?

[crisss1205]

I would like to know how Apple puts OS X as a boot up volume on portable hard drives. I know that when I want to the Apple Store to diagnose my MacBook Pro they connected an external portable hard drive and they booted up their version of OS X 10.5. Does anyone know hot to do this so I can take it with me and boot it on another Mac.

With the drive plugged in go to Apple Menu>System Preferences>Startup Disk (third row down in the panel) to choose the startup drive. The external drive needs OS X installed on it of course.

To install OSX on your portable hard drive just connect it and boot from your install/restore DVDs, format the hard drive appropriately, select it as the install volume and install away. Hold down option to select it to boot from when your start up the computer and it's connected.
