When running the installer from the graphical (MXM) interface you will not get any video output on the screen (due to an incompatibility issue with the linux kernel and the Xcalibur video chip). You can still run the menu options as explained above, but you will not see any output to the screen. You can however get the information from the screen by retrieving the ltools.log file from the game save dir after installtion.
On the first install the installer will make a compressed image of the C-drive, for safety reasons and later restore capabilities. This will take some time, so just wait some minutes. When the installer is done the LED will turn from orange to blinking green, indicating that it's safe to turn off the xbox.
