Hi everyone, I'm about to install a PC card in the mac pro I have as the title suggests. Problem is I really like my boot screens, specifically holding option. Its a 2008 mac pro 3,1 running sierra, and windows 10. For whatever reason Windows DOES NOT show up in start up disk under system prefs. And since windows 10 "isnt supported" on this Pretty 8 core PC with an apple logo on the case, I do not have bootcamp support installed in windows. So my only way of changing OSes is with the option key. Does anyone know of any third party apps that will allow me to do this in both windows, and os x? I know about bootchamp, I'm about to test it out. But that still leaves the question of how to get back into os x from windows... I know what youre thinking, leave the current card in or buy a new one. I just cannot stand this ancient x2600 radeon any longer, and I have 3$ to my name so purchasing a Mac card at 200$ more than the card is worth is not an option. The card in question is a GT740, as far as I can find with endless hours of searching is that it cannot be flashed over.
