Startup disk missing

I accidentally deleted partition Macintosh hd-data and now my computer won’t startup. It doesn’t give me an option for startup disk. I am not very tech savvy but am able to click a mouse and type. Lol. Any help is appreciated. (My Mac was super slow in everything and I only use a few items such as messages, calendar, adobe, chrome)

Assume this method was used >> Use Disk Utility to erase an Intel-based Mac


Then the next step is this method >> 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.
