How to copy USB

Hi,

I had a hard time creating the piratebox. I ended up bricking it but manage to unbrick it throught serial. Then, I finally got to install the piratebox.

I would like to use another USB stick. So I simply copy and paste the folders and files into the new stick. But when I put the new stick in the piratebox, it doesn't start. How should I do?

If I redo the piratebox installation with my new stick, would the installation on the other stick still work?

Thanks a lot.
