I am trying to factory reset a 2014 MacBook Air. I erases the hard disk and restarted to reinstall the OS X Yosemite but when I get to the stage to select a disk to install on there is no disk to select. I am worried I have done something wrong. Any ideas ?

MacBook Air 13″, macOS 10.15

Was this method used as per Apple Support Docs >> How to erase an Intel-based Mac


Was this method used to Reinstall as per Apple Support Docs >> How to reinstall macOS especially this portion 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.
