        High Sierra GM installation failed with an "com.apple.DiskManagement error 0" message.

        It offers me a "Restart" button so that I can retry the installation, but without option to change anything I just get again into the installation and it fails with the same error message.


        I have a Mac Mini with a 1 TB HD, so I understand the install isn't trying a conversion to APFS (which went incredibly well in my MacBook with an SSD, by the way).


        How can I get out of this loop and return to good old Sierra I had before?


        Is there an easier solution than recovery and restore from Time Machine?
