Driver needed to install Windows in Chuwi Vi8 dual boot tablet

Hi, i own a Chuwi Vi8 dual boot tablet. I want to use the full 32GB HDD for Windows, so I need to reinstall Windows (I know how to backup and restore drivers in order to keep the tablet working), but when I try to install a new fresh copy of windows, it shows a message saying that a DVD, USB or Hard disk driver is missing. May be you can help me and send me that driver or drivers.

Best regards
