I would like to create a chrome os bootable USB drive. From http://www.chromium.org/chromium-os/...-Prerequisites the step to "Initialize the build for a board" says to use "./setup_board --board=${BOARD}" before build the image. When I use this command, I get:

Sorry, try again.
Sorry, try again.
Sorry, try again.
sudo: 3 incorrect password attempts

I don't know how or where to set the password. Please tell me if this is not the right forum, and if you know, the correct forum to post to.

Thanks
