Getting a USB to be recognized as boot drive.

Hi guys, I currently have a Success ful dual boot windows + Hackintosh system using a Corsair Flash Voyager GTX as my macOS drive. It works great... when the motherboard actually recognizes the drive. If it doesn't it just boots straight into Windows. Does any have any ideas how I can get my USB boot drive recognized every time, or is that just the nature of USB drives?

Motherboard is a MSI B250M
