I’m trying to return my Mac book air to the factory setting I deleted the hard drive and lm trying to reinstall OS X. There is nothing in the box where I am to select the disk. Not sure what to do any suggestions?

Was this method from Apple User >> Use Disk Utility to erase an Intel-based Mac

Then us this method from Apple >> How to reinstall macOS This will require a working Internal Connection. For best results us an Ethernet Cable to Router

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.

Hi,

Go back to Disk Utility > select the top item on the left (Apple SSD or something like that) > click on Erase > select Mac OS Extended (Journaled) and GUID and follow prompts, then go back and try the install.

You're welcome.

This WORKED! It took 6 hours to rebuild the disk (or reformat, or whatever) but it worked! Thank you!
