hi Nic and welcome here,
Anyways...the install script worked very well except choosing my keyboard was not possible as it had to many options for 1 page (it started at 44 for me).
Do you have installed obarun from console, so without graphical environment? i need to change this behaviour about displaying the list. Anyway, on console i use a trick : SHIFT + UP / DOWN arrow to be able to see the top/bottom of the screen. I believe that this trick do not work for everybody, depends of the hardware.
