Hey everybody, i read and tried a lot about this but since I haven't succeeded, I am turning to you knowledgable folks Alright so here it is: I am running a Mac Pro 1,1 (MP) with El Capitan (EC)(pike boot.efi) and Windows 7 via bootcamp. I have a non-osx card GTX 660 in the MP which works like a charm. However, as you know you can't see the boot screen. I tried 'blindly' selecting the drives when holding alt after the chime at startup but that somehow doesn't work well. Win7 will start, EC not. So I decided to do it via software. In EC I selected Win7 to be the startup disk. This works fine. However, how can i switch from Win7 to EC? I cannot do it via the bootcamp program in Win7 because it doesn't work. I tried installing the whole bootcamp drivers package, that didn't work. It told me my machine doesn't support x64. So I installed most drivers by hand. Everything works fine, but I still don't have the little bootcamp icon in the task bar and when I want to launch it manually Win7 just won't start it. So I tried installing the bootcamp driver package another way (http://tsentas.net/bootcamp-x64-unsupported/). Installation went fine, but after a restart I ended up with a Blue Screen and I had to F2, F8 and then select 'start the last Win config that worked' or something like that (don't remember the exact words). So, this is my dilemma. Any ideas how i can boot from Win7 to OSX without the bootcamp task bar program? Thanks guys.
