Boot Camp always tries to open?

Ok so I tried to install XP from a .iso (Yeah obviously it didn't work out) but now whenever I turn my Mac on it gives me a message that says "No bootable device detected - please insert a boot disk and press any key." How do I keep it from always trying to start up XP?

Does anyone have any ideas for me? Please?

Power on and hold down the Option key right after the startup sound. Keep it down and a menu should come up. Do you see OSX as a boot option? If so click and boot into OSX. Then once in OSX open System Preferences and Startup Disk and click on OSX and then on restart. It should then start in OSX. I would also run Bootcamp again and remove the bootcamp partition till you get the proper Windows CD for the install.

If the above does not work let us know.

Y'all are awesome.
