Stuck on an endless loop after MacOS migration on a Mac cheese grater 3,1 from 2008. Is there a way to interrupt this loop and revert/reformat the hard drive with OCLP 2.2.0? I was migrating to 15.3.1

Any help to savage this uncontrollable computer is welcome. I don't care about loosing any data. Someone knows the magic trick? Or do I have to throw the Mac into the dump site for electronics?
