Create your USB installation media using Clover installed in Legacy mode.
Disconnect Windows drive, connect OS X-to-be drive, insert USB drive in USB2.0 port
Boot to USB and install OS X. Run MultiBeast post install to install FakeSMC, networking and audio, maybe 3rd party SATA drivers/USB3.0 kexts. Install Clover Legacy Mode.
Shut down
Reconnect Windows drive.
Boot to BIOS and make the OS X drive first in HDD boot order. Save&Exit, continue boot.

How do I make a USB installation media using Clover on Windows?

You do not. You need a working PC-Mac or a real Mac running OS X to download the installation app and create your USB installer.

Lacking either of these, you can purchase the Snow Leopard installation DVD from Apple and use iBoot + that DVD to install 10.6.3 and update to 10.6.8 so you can download El Capitan provided your hardware is Haswell 9 series or earlier. If running Skylake hardware iBoot option is not available.

So if I had an dmg of Snow Leopard not the DVD would I still be able to use iBoot?

No. Requires the retail DVD.

Okay, what version of iBoot should I get and is the installation process still the same?

Follow this guide: http://tonymacx86.blogspot.com/2010/04/iboot-multibeast-install-mac-os-x-on.html and everywhere it says iBoot substitute iBoot Haswell since you have a GA-H97 board unless you are using a broadwell CPU, in which case use the iBoot Broadwell.

Okay and will my graphics card work with Snow Leopard?

I doubt it. Since it will not work in Yosemite or later without nVidia drivers it will not work at all in SL. SL was never updated past the 9800GT days.
