NO DISK on "Select the disk where you want to instal macOS" screen

I don't know what you did, exactly, so here is what you should do with a used computer that was not prepared for the new owner. You will need an Internet connection for the following which will install the original version of macOS that came new from the factory.

Internet/Network Recovery of El Capitan or Later on a Clean Disk

1. Restart the computer. Immediately, at or before the chime, hold down the (Command-Option-Shift-R) keys until a globe appears.
2. In the screen menubar is a Wi-Fi icon. Click on the icon to select your Wi-Fi network from the list. Enter the network password as requested. If you have an Ethernet connection, then ignore this step.
3. The Utility Menu will appear in from 5-20 minutes. Be patient.
4. Select Disk Utility and click on the Continue button.
5. When Disk Utility loads select the target drive (out-dented entry w/type and size) from the side list.
6. Click on the Erase button in Disk Utility's toolbar. A panel will drop down.
7. Set the partition scheme to GUID.
8. Set the Format type to APFS (SSDs, only if installing Mojave or Catalina ) or Mac OS Extended, (Journaled.)
9. Provide a volume name, usually "Macintosh HD."
10. Click on the Apply button, then click on the Done button when it activates.
11. Quit Disk Utility and return to the Utility Menu.
12. Select Install OS X and click on the Continue button.
