Hi10 Pro reset to Android and Windows 10

I have the Chuwi Hi10 Pro PQ64G42161100811 and I have used it with Ubuntu. During the install I’ve wiped all existing partitions. Now I would like to bring it back to its original state. So with Android and Windows 10.

Could you please provide me with an image of this original state and/or instructions how to install it?
