Hello, I am quit new at this.
I have a UBS drive with 16 GB, and it is formatted in Fat32.
I have GhostBSD on a laptop installed with an older installation, and there it work just fine. I just plug in and go.
I have installed GhostBSD on my desktop, and there it does not work. I plug it in and nothing happens.
I have no idea where to start, and I have tried to consult the FreeBSD handbook, but I know GhostBSD is supposed to just work.
friendly regards
