Disk is not convertible to APFS

I cannot reinstall MacOS on Mac mini, when 2 minutes are left before the installation is completed, the system gives an error: Disk is not convertible to APFS


The same error occurs with external hard disk drives


How can I solve this problem? Thanks!


PS: I don't have a backup due to the fact that I want a clean OS

Mac mini, macOS 11.0

Sorry one more question, are you doing this erase and reinstall from another drive or in macOS Recovery?

If from another drive, then use Recovery Mode to format and install MacOS on the drive.


If that doesn't help, then run Disk Utility Repair while started up in MacOS Recovery and see what it has to say about the drive.
