Hello,
That screen is is for the internet recovery OS. It doesn't sound like you are getting the alert screen but wanted to paste that info incase it helps.
About macOS Recovery on Intel-based Mac computers - Apple Support
"If you see the globe and alert symbol, try these solutions:
- Make sure that your Mac can connect to the internet. If you're not prompted to choose a Wi-Fi network during startup, choose a network from the Wi-Fi menu , if available.
- Press Command-R at startup to try using the built-in Recovery system instead of internet Recovery.
- Connect to the internet using Ethernet instead of Wi-Fi, or vice versa.
- Connect to the internet from a different Wi-Fi or Ethernet network. Your network configuration might not allow the internet access that macOS Recovery needs.
- Try again later, because the issue might be temporary.
- Start up from another disk or volume, if available, or use a bootable installer to reinstall macOS.
If you still need help, please contact Apple Support."
I hope this helps.
