Why ISO images of some flavours of Ubuntu can be put on USB stick by dd command and boot successfully, while others flavours don't? Moreover it looks like it is dependant of particular USB stick too. I tried with standard Ubuntu:
$ sudo dd if=./ubuntu.iso of=/dev/sdd bs=8129
And it works like charm, I mean: boot and installs or run live Ubuntu. But when I use another USB stick prepared the same way, it fails to boot with Operating system not found BIOS error.
When I try the Ubuntu GNOME, then it simply does not boot with the same error as in previous example, regardless of which one USB stick I use.
I know, that there is Startup Disk Creator application in Ubuntu, but I have been convinced, that it is only a GUI facade for simple dd command, and I can always use dd to create bootable USB stick, at least for Linux. Am I wrong?
