first things first, backtrack is not for newbies. im not being mean, im just saying it as it is and im not the only one who will tell you that. second, you said that the 150gb partition is unformatted, format it to reiserfs then try running the installer. also get gparted if you want a good partitioner, any partitioning done through windows is garbage. as for the gui for your wifi card, in terminal type "wicd" then "wicd-client" (without the quotes). that should open up a gui for the wifi. in regards to the bluetooth mouse, just try it and see. and in terms of your driver installation question, what kind of driver are you trying to install?
