How can I remove clover and start over?

Currently I have MacOS Sierra installed on my hardrive with clover, but I just need to start over, wipe the drive, and install Windows. I have the Windows install USB ready to go, but I can't seem to actually use it with clover starting on bootup. Can someone please, please help me out.

I spent all day trying to get my new pc-build hackintosh ready, but at this point I just really want a functioning Windows computer; forget Mac. I don't have time for this; maybe later I'll try again.
