I did an erase on my mac book air and now all i get is a flashing question mark

I erased my MacBook Air but it doesn't give me a choice to reinstall the OS. All I get is a flashing question mark. How do I reinstall the OS if I don't have startup disk?

Was this method from Apple Used ? Use Disk Utility to erase an Intel-based Mac


Then this would be used. How to reinstall macOS


Follow these guidelines during installation:

  • If the installer asks to unlock your disk, enter the password you use to log in to your Mac.
  • If the installer doesn't see your disk, or it says that it can't install on your computer or volume, you might need to erase your disk first.
  • If the installer offers you the choice between installing on Macintosh HD or Macintosh HD - Data, choose Macintosh HD.
