Why are all my bootable USBs named "El Torito"?

All my bootable USB sticks (and I have quite a few) all show up in rEFInd named "El Torito". I have no idea why. Even freshly burned images are called El Torito. I didn't do this, and I've been using rEFInd for a while and used it pretty extensively. I even themed it (see attached).

But El Torito? I don't understand. How can I undo this?

rEFInd attempts to find a label for each filesystem it reads. In the case of hard disks, these can be filesystem labels or partition names. In the case of CDs, these are most likely to be filesystem labels. If a label is not found, rEFInd falls back to describing the filesystem (e.g., "500 MiB ext4 volume").

What you're seeing is most likely a filesystem name. ("El Torito" is the name of a CD-ROM standard that enables embedding a FAT filesystem onto an ISO-9660 disc. It's used by bootable disks. Chances are the bootable USB drives you've tried were prepared with this in mind, and the filesystem was named that way but not altered for the bootable USB drive. rEFInd's own bootable USB drives are prepared in this way.)

Thanks, Rod! Mystery solved!

I had been investigating various bootable images trying to find a combination of rescue/repair/revise utilities that suited me. One of them must have been the kind of image you described.

In the end, my USB stick that's permanently dedicated to rEFInd was all I needed.

Thanks!
