Deleted Macintosh HD. Don’t know what to do.
I wanted to reset my mac to factoru but accidentally deleted the Macintosh HD. Every time I press the command R keys, a globe appears. Afterwards I don’t know where ti go from there. If I turn on my mac a flashing folder with a question mark appears. I need my mac to be working and restored. What should I do. How do I reinstall the Macintosh HD?
i have 2019 macbook air 13 inch.
