Q: MacPro no display when External HD plugged in

Hi there,

 

I'm trying to use my external HDD...My Book Thunderbolt DUO (formatted ex-fat) in BOOTCAMP. So, I need to plug my external in before I start my computer, right? Because plug n play isn't supported. When I do that, my computer starts up fine, the mouse has lights...but nothing shows up on my display.

 

Then I force shut down the MacPro. Disconnect the external, and boot it up without the external. No problem. Boots up like normal with the display working perfectly.

 

I really need access to my external w BOOTCAMP for work. I'm not very tech savvy and appreciate the help. Thanks!

Mac Pro (Late 2013), OS X Yosemite (10.10.5)
