Same result.
Also tested creating a bootable USB-stick with a Centos ISO-file. No
problem.
Until recently, whenever I made a bootable USB drive from an ISO-file,
to use it I had to go into the BIOS and allow "legacy" devices precedence
over existing secure-boot devices.
But recently, with the Fedora 32 stick I made, I had to disallow the
legacy devices as the ISO was intended for secure-boot.
Perhaps your CentOS stick is secure-boot, thus working for you
but the others need the "legacy" change to the BIOS.
