Just found some old notes, dunno wheter they still apply but its worth a try.

1. Make an Image of your choice by the creator. I made an post about that. Copy the resulting ISO to an USB Stick.
2. Boot in the new PC with Ubuntu or Knoppix Live DVD. Mount the USB Stick.
3. Copy the ISO to the Harddrive. With dd.
dd if=webconverger.iso of=/dev/sda
4. Reboot, thats it
