Need to delete user data and reinstall

Hi All,

I have an old IMAC that I am trying to wipe the data and reinstall or upgrade the OS to Snow Leopard.  The user forgot the passwords to both accounts.

I cannot get it to boot to the internal CD/DVD drive, an external DVD or a USB.

Holding down the C key didn't work, and I also tried booting from firmware "Option"+"Command"+"o"+"f"

Does anyone know what I need to do to get this to boot from something other than the hard drive.



Answer this question I have this problem too

Is this a good question?

Here's the Startup Key options: Mac startup key combinations This series needs a wired USB keyboard for the options to work.

To bootup into the startup manager, hold the “option” key once you hear the startup chime. You can let go once you see the apple logo.
