So hd0 is the USB stick. I'm not familiar with the view you have
there, so try things like:

  ls (hd0,apple1)/
  ls (hd0,apple2)/
  ls (hd0,msdos2)/

I'm guessing appleX gives you a UEFI view, and msdos2 an MBR view.

If you see directories, try listing them. (Command recall should work
to save typing.)

(In the other thread,  c   didn't work because you were already
at the command prompt that   c   gives you.)

Cheers,
David.
