I've just install Windows 8 on my iMac using bootcamp and now when I restart my machine Windows 8 starts but there doesn't seem to be an obvious way of starting OSX again.

Is there a keyboard key I need to hold down during start up that will allow me to boot back into OSX?

Part of the problem is that Windows 8 is not officially supported by Boot Camp at this time: of course how to install and use Windows 8 through Boot Camp is well documented:… – Ramhound Jan 30 '13 at 12:05

All one has to do is tell Windows 8 to restart and then hold down the Option key. On restarting, this will bring up a boot OS menu which allows one to select the OSX boot drive.

Note that it still possible that Windows installation broke your OSX boot partition. In that case you simply need to boot on a restoration partition or on an OSX DVD and do a dick verification/reparation. It will update your boot partition and restore OSX boot. – Dimillian Jan 30 '13 at 13:11
@Dimillian77: Hmm, I wonder how exactly "dick verification" works? ;) – Karan Jan 30 '13 at 18:46
