First ever build https://pcpartpicker.com/user/smsmith2010/saved/JZhb8d and I wouldn't say its been smooth sailing, but I've been able to figure out my issues a long the way by reading the manuals and following instructions carefully. But now that my hardware is assembled, I'm being stumped by how to get my dang USB drive to boot up with Windows 10. It shows up on my bootable options, but I am unable to actually boot to it. The USB is formatted to exFAT i believe, and I only have a macbook to use elsewhere, IE cannot download rufus. Please help
