I installed Ubuntu accidently on my iMac thinking I would be able to run a Emulator for PS3, I was following a tutorial and apparantly in the mess erased the mac operating system along with it's files to boot into it. I have done Command R. Nothing happened booted into Ubuntu. I have tried Command + Alt + R. Nothing happened again booted into Ubuntu. I am trying to restore the iMac back to Snow Leopard to where it was originally. Please Help.

I believe on an early 2009 iMac, insert the Snow Leopard disk

and reboot holding down the C key to boot directly. Make sure

you are using a wired keyboard.

If you did somehow mess up the Ubuntu install, there will be no Recovery HD.

Also, early 2009 iMacs do not support internet recovery.

If you don't have the original Snow Leopard install disks you may have to purchase them.

Thank you so much you are a life saver, It worked.

You're welcome. I have an early 2009 24" iMac that I sometimes

play with trying various things and have a Snow Leopard disk

in case I want to start over. Actually had Win10 running on it

as a sole OS at one point among multiple flavors of Linux.

Not good. I don't know what else you can do. Maybe someone else does.
