Not sure if I need to make a dedicated separate thread/post for this or not, but I'll post anyway and if it needs to be moved, feel free to move it. It seems like the appropriate area to post.
Okay, so I finally got a motherboard capable of UEFI booting. Specifically in question, the motherboard is an Asus Z87-WS. And yes, UEFI booting OS X/macOS actually works (yay/yes/YESSSS) as opposed to my Asus P9D WS. However, single drive UEFI multi-booting is quite strange and doesn't function very well with this motherboard and was wondering if someone has the solution.
So, single drive only one OS installed, macOS, works fine for UEFI booting and everything. Everything seems to run quite well. However, when I try to do a test install of single drive UEFI multi-booting, running MultiBeast and installing the UEFI bootloader doesn't seem to work, as the UEFI boot option to the drive does not appear and I am not able to boot to the Hackintosh drive in order to reach the Hackintosh bootloader which shows the options for all the OSes installed and which to boot to.
On another note if it helps, I noticed that after installing the Mac OS, running MultiBeast, then installing Windows seems to be affective rather than installing MultiBeast as a last step because when MultiBeast is installed as not the last step, but rather directly after the Mac OS installation, the UEFI boot option remains. Although it remains, Windows acts quite strange when selected to boot into using the Hackintosh bootloader as compared to the Windows boot manager option. So from this, I haven't really found an acceptable solution.
