Help with Mac OS reinstall- disk not located
I'm in a jam. I am erasing a MacBook Air to give to a friend and somehow erased the disk where the OS was installed. It is a 2012-ish MacBook Air with SSD. I used MacOS Recovery to erase the disk but now when I restart, the blinking ? appears. I then restarted in MacOS Recovery, checked Disk Utility and got nothing. I then tried to Reinstall OS X but there too, the destination disk cannot be located. Any suggestions? Thanks.
