Update: Issue solved! Seems the reset wiped the settings on which driver to use. I remote into the Mac Pro to correct it as it MUST be corrected on the Mac Pro to update the settings in its PRAM/NVRAM otherwise it will keep using the default drivers even if those settings are adjusted by booting into the drive on another computer. I'm not sure how to get bootcamp working though but at least everything works. Edit: I had it reversed, it is a NON-flashed gpu I recently got a Mac Pro on impulse and didn't realize that the GPU it came with was flashed instead of being natively supported. This provided some obstacles, but over all ran fine, until I attempted to set up a bootcamp partition. I ended up getting stuck with the "Nothing bootable please insert" loop and since I had only the flashed GPU I couldn't simply option key at start up to choose where to boot. I realize how foolish this is now, but to resolve this I attempted to reset the NVRAM (option + command + P + R) and now the Mac Pro has no video, my displays all claim there is no signal. I believe I may have un-flashed the card making it useless unless I replace the GPU. I bought the Mac Pro for a few hundred (lowest xeon 2010) as being in college I don't have the means to go higher, so buying a new graphics card that has native support feels like I might be digging a deeper hole. I'm not sure what to do at this point, is there a way to fix this? Just recycle it or scrap it for parts? I'm stuck in a pit of despair as all my choices just seem to make a bad situation worse.
