I've used EasyBCD before to attempt to set up my hackintosh, but after running it and setting up the OSX chainloader, windows stopped showing the boot selection screen and simply boots straight into Windows 8.1. I'm using UEFI, and can still boot into OSX using the F12 button as my system POSTs. Currently, however, I'm focused on simple rebuilding the BCD so that EasyBCD can actually start.
