Backtracker might have worked had you created it back when the notebook was new, backtracker was flakey at best but did work for some people.

You can also go to Asus Support Download and download all available drivers for 8.1 and Windows 10 is there are any for 10 is not, just get the 8.1 drivers all of them. then Download an 8.1 install USB media from MCT Download Windows 8.1 Disc Image (ISO File). Since your computer came with 8.1 it is already registered in the Microsoft activation servers so just skip entering the product Code unless you actually have it. and it will auto-activate, then unplug from the internet and install the Asus drivers and software.
