Reinstall stock Android on Chuwi HiBook Pro

Good morning, I wanted to ask something. I have a Chuwi HiBook Pro and wanting to try to update Android I permanently deleted its partition and installed Android x86 in its place. But since i There are no drivers. I would like the original Android (Android 5.1 Lollipop). How do I reinstall it if I can’t use the Intel Phone flash tool because I can’t get into the DNX Fastboot mode due to the fact that I completely deleted the android partition? I still have the Windows 10 partition intact and working. Thanks to anyone who wants to help me.

I am sure @manonegra222 knows how to do it :wink:
