Please see the installation instructions: https://www.debian.org/releases/stable/installmanual
It is not correct to pre-format your install media, and pre-copy other files onto it, before copying the installation .iso The correct instructions for writing a USB (or other) installation medium are in section 4.3 of that installmanual. In particular, the destination target of your dd command should be something similar to /dev/sdb _NOT_ something like /dev/sdb1 --- and don't forget to `sync` after the dd. If you still have trouble, seek help at the #debian IRC channel at oftc.net.
