No disc to install to after reset
My son reset his laptop and now the installation does not continu. It appears that there is no installation disc active to install MacOS Catalina. In the disc help menu I can put back a drive but it warns that this procedure cannot be undone. That leaves me hesitant to press the button. On the disc is nothing of value, my son works in the cloud. What can I do?
MacBook Air (2020 or later)
