I updated F7 UEFI/BIOS to F10 UEFI/BIOS. Didn't solve the problem.
Have you tried connecting only Windows drive, installing, updating to max, install Steam, play games, and then and only then connecting the OS X drive and resetting UEFI boot order?
This is last thing I can think of - I never had this kind of problem and am unable to reproduce it.
