Long story short - I've got a Mac Pro 5,1 and successfully installed EFI Windows 10 Pro on a dedicated SSD. OS X Yosemite's Startup Disk panel however, isn't so smart and assumes it's a traditional BIOS emulated install and I get the "No Boot Device Found" error if I switch to Windows using the Startup Disk panel. Holding Option at startup and choosing EFI Boot works flawlessly, however.

So would I need to use the bless command to unbless the Windows install partition and then bless the EFI partition on the same drive? Not sure which commands to use; the tutorials I've found are all for Linux installs.
