I have formated my Targa 250GB external Hardrive with WBFS manager and dragged Super mario bros Wii over.

When i start USBLoader, WiiFlow or Neogamme to boot the game, i get this error message:

"An error has ocurred.
Press the eject button, remove the disk and turn off the power to the console.
please refer to the wii operations manual for details. "

What seems to be the problem? and one more thing, i didn't get any picture up, (picture of the cover) how do i fix that?

I have version 4.2E, and followed this guide to softmod:POTHSPROJECTS • View topic - How to: Softmod Your Wii on 4.2 Firmware (ANY SERIAL #!)
