Lost Windows 10

I have a CHUWI Hi10 AIr model: cwi 529 tablet.
I lost WINDOWS 10 and even the partition. Cannot reinstall WINDOWS 10 with a USB key.
Could you send me a link to download all the files to completely reinstall the tablet with all these basic files including WINDOWS 10.
Thank you in advance,
Regards,

Thanks I was able to download them onto a USB drive. Are there steps I need to take to completely reinstall?

You must do the same as in this tutorial with the files downloaded in the first link
