If you are booting form a disk or some sort of image, make sure you have the correct one.

I have spent hours trouble shooting to find out I had the wrong recovery disk. It was for an older mac I once owned.

Try a command-option-r (all thee keys at once) boot. That should get you to Internet Recovery where you can access Disk Util to format the drive to Mac OS Extended then install the OS.

That will install whatever OS came with your system.
