    My favorite way to create a boot media is simply to use cat. No arguments, no shenanigans just a cat into the device :

    cat debian.iso > /dev/sda

      iirc there was a reason you should use dd instead of directly copying the data, I think something to do with device block alignment or something?

        That could be possible but for the moment I didn’t encouter any problem with cat. I think I’m going to stick with it for the time being.

      One caveat is that you will need write access to the drive, which probably means you need to run as root — can’t run that with sudo as-is, unlike dd.

        Yep that’s right, but I use fdisk to check my drives before writing on them and it also requires sudo…

          Right, I just meant that you can’t sudo cat file > /dev/sda but you can sudo dd ..., because IO redirection isn’t elevated to root with sudo. I’m not saying anything too profound :)
