As of Porteus Version 1.1, the officially supported method for installing Porteus to a flash drive or hard drive is to burn the ISO image to a CD following the instructions written above, then boot Porteus from the CD and run the program 'Porteus Installer', which can be found in the KDE, LXDE, Razor or Xfce menu under the 'System' heading.
