Hey all! I recently downloaded backtrack 4 prefinal iso and booted it on a usb drive. It works fine but when I try to install it it always gives me an error at 90% when the system is "Detecting Hardware". From what I remember in the error message "Too many input devices... Connection to Server X lost". I tried to boot it from a dvd and I checked the integrity of the iso image (md5 checksum) but nothing worked :S. Is this a problem in my hardware setup (Incompatibility) or it is a bug?
