chuwi Aerobook 13.3 SSD and Driver

Hi Guys.
I am start my new Chuwi Aerobook 13.3 but i am see my file explorer section my all storage use in C drive. I am see my c drive is 237 gb that is my all SSD.
So i need to partition this SSD in different drive. How can i do this.
And i am not find any mother board drive in my hard drive or not found any disk.
So how can i get my laptop drivers like graphics driver, audio drivers etc.

Advanced thanks for helps
