Need to delete user data and reinstall
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.
