CompExpert :

hi,
the only way to uninstall osx mountain lion is to format (erased) your internal hard drive and reinstall your old operating system the mac osx installation disc. make sure to backup your data to a external usb hard drive before doing this.

here is how:

1.if you have leopard 10.5 or snow leopard 10.6 you will need osx installation disc
2.insert installation into dvd drive and power off your computer, power on your computer again right away hold down C key, keep holding it
3.until you get to a language screen, click the right arrow to passed it.
4.on the next screen, look at the top menu, you will see the word "utilities" --->>> disk utility
5. within disk utility window, select your internal hard drive and select the erase tab then click erase.
6. after completed, closed disk utility window and continue with the installation.
