Startup disk missing

When I reinstall my MacBook Pro, the startup disk is missing, and I cannot complete the process. How do I fix that?

Boot into Internet Recovery (Option Command R) and from the dropdown menu: Utilities>  Disk Utility> run the First Aid on your Macintosh HD (and the "Macintosh HD-Data" volume as well if Catalina/Big Sur) If errors are found and repaired, run again until no errors reported.


Disk Utility>View>Show All Devices The best sequence is —

• Volume level

• Container level

• Parent drive
