Yeah, you might have deleted the operating system. I would really go to Apple support and have them reinstall it for you. If you are on the EFI screen but no icon label with MacOS.
If you have a wired internet connection you might try and reinstall it yourself.

Do you have Time Machine backup? You can install macOS on an external hard drive and then boot his troubled MacBook system.

If this is a new Mac computer with the Apple silicon M1 Chip (MacBook Pro (13-inch, M1, 2020), MacBook Air (M1, 2020), Mac mini (M1, 2020)) then you need to power on the machine then press and hold the power button to get the start up menu. Then click on Options, and you should see the information here.

(Note: the M1 chip holds the entire OS in it)

For older models, you need to make sure you are on Ethernet (recommended). The Internet Recovery procedure will get you to connect to your wireless connection if you can't use Ethernet. When you power up, you need to hold the Option+Command+R until you see the Apple logo or the globe icon.
