... huh? This makes no sense. There is no "boot command", and there is no need to mount a USB device to which you have written a Debian installer ISO image. In fact, mounting at any point during this process is bad. All you need to do is follow the instructions in the release notes. "Burn" (copy) the ISO image to the USB device, without ever mounting it. Then tell your computer's firmware/BIOS to boot the USB device, possibly selecting either UEFI or Legacy mode as appropriate. That's it.
