Then I executed the command in terminal: sudo dd if=debian-live-10.2.0-amd64-xfce+nonfree.iso of=/dev/sdb bs=4M; sync which resulted in a non-working flash drive; when I looked at it in gparted, there was a small black partition, and the rest was empty. Doesn't matter now, I'm zeroing the flash drive as I'm typing this. How long does it take to zero an 8gb flash drive anyway? I forgot to put "status=progress" in the zeroing command, so now I don't know how long I have to wait.
