Q:

Does the Buillt-in Apple Recovery Partition already have an OS X Image?

Does the Buillt-in Apple Recovery Partition already have an OS X Image or does it download it over internet?
I am asking because if it does download over the internet I want to create my own recovery partition from a Yosemite Install application.

A:

It has to download. In favor of saving space on your hard drive, the Recovery HD is 650 MB of various utilities including one to download and reinstall OS X.
