I am having trouble setting up RAID on my new Windows installation

I built a small computer with no CD drive. I can legally get Windows through my University. So I created a bootable flash drive in order to install Windows.

However, I have 2 1TD HDDs that I wish to set up as a RAID for my Windows installation. The problem is, I don't think my motherboard supports RAID in the BIOS as there is no option for RAID under the status. However, when I go to my motherboard's download page, there appears to be RAID drivers:

Do I need to install these drivers in order to setup my RAID? How do I install drivers onto a motherboard without a CD drive?

If my motherboard doesn't support RAID at all, is there still a way to set one up?

Thanks!
