If you can't start up from macOS Recovery - Apple Support

Hi lionleon1,

Based on your device description, I'm assuming you have an Intel-based MacBook Air. In that case, you can force it to start up from Internet Recovery: hold down Option-Command-R as you power on or restart your Mac. If successful, a spinning globe will appear, or you'll be asked to connect to a Wi-Fi network.

If that doesn't seem to do anything, maybe there's an issue with your internal keyboard. Try connecting an external wired keyboard and hold down either Command-R or Option-Command-R as you power on or restart your Mac. Release the keys when the Apple logo and a progress bar appear, or when a spinning globe appears.

(If you're using a Windows keyboard instead, use Windows-R or Windows-Alt-R respectively.)
