Q: 2002F warning message on my 2012 MacBook Air after erasing my files - what have I done wrong?

I admit I'm a rookie at this kind of thing. I was trying to clean down my MacBook Air 2012 since I have a new one and think I may have accidentally erased the startup disk.

I've followed the steps listed here: A flashing question mark or globe appears when you start your Mac - Apple Support but cannot get as far as the Startup Manager. I'm stuck at the grey screen with the globe showing a warning symbol and the error message 2002F

 

Appreciate all advice.

Thanks,

ER

MacBook Air, OS X Yosemite (10.10.4)
