usb-creator-gtk searches files by extensions and checks them differently according to extension. If it is iso file, based on the code listed here, it has to be in Joliet format:

/usr/lib/python3/dist-packages/usbcreator/backends/udisks/backend.py +147

cmd = ['isoinfo', '-J', '-i', filename, '-x', search]

Does it have to be this way? Debian's live DVD, for example, debian-live-10.0.0-amd64-gnome.iso, is a perfect iso 9660 file but does not have Joliet extension, isoinfo reads it fine, dd writes fine and boots fine. Why usb-creator-gtk does not want to handle it?

Next time if you know it is an proper bootable DVD and usb-creator-gtk fails, just try dd.

Or, try to rename to an img file just write to usb.
