I'm running Mavericks on my Hackintosh installed on SSD with EFI boot option with a Clover bootloader. On second SSD I have Win 8.1. Both systems are visible in Clover but Mac is primary booy device as default. Only chaning boot device in Mac settings can change to start Clover with chosed Windows, but only to next time when i start Mac OS. I won't remember about changing preferences every time I run Mac and Windows is my main work system so it is highly recomended that it shold be always main boot system. Please help :/
I've managed to find my Windows 8.1 EFI drive type (or code) and entered it as Default Boot Volume in Boot, checked IgnoreNVRAMBoot and additionally in GUI I've added Custom Entry with Type / Other, VolumeType / Internal and Hidden checked - that prevents from doubling Windows EFI boot (hide UEFI Internal from EFI).
Everything is fine - Thread can be closed
