UEFI - Installing Windows 8.1 to a new computer

Been away from PC world for some time and I need some help. I bought a new computer, which doesn't have OS installed. Computer: motherboard ASROCK Z87 EXTREME3, I5-4570 3.2GHZ, R9 280X and a 240GB Crucial SSD. My GPU supports an Hybrid BIOS (hybrid between Legacy and UEFI) which made me look for information, what is UEFI.
So I would like to set up my computer, so it would take advantage of UEFI which means I have to install my Windows 8.1 in UEFI mode, right !? I have it on a disk. From couple of tutorials I understand that when I start installing Windows, when selecting from where to boot, I should choose - UEFI:''my optical drive'' (SAMSUNG DVDROM 16X SATA BLACK SH-118BB/BEBE)
Is that all ? In couple of threads people have said something, that their optical drive does not support UEFI or that their Windows disk does not support UEFI. Should I be worried about these things ? Doesn't installation recognize itself, that the computer supports UEFI and install it accordingly ?

Computer hasn't been even unboxed yet, it's waiting for me to arrive.

Thank you in advance

  1. The UEFI is a Windows base program that allows you to overclock your CPU and adjust your fan speeds. It doesn't do everything your Bios will do but most of the most common things you'd want to do. It comes with your motherboard.
  2. Both wrong. UEFI is a newer form of bios. Updated for modern things. You shouldn't have to do anything special to use UEFI. You didn't for the bios of old, you don't for UEFI either.
  3. I've never heard of a drive not supporting UEFI that doesn't sound right as booting via UEFI just means that UEFI will look for something different from the drive than a regular BIOS would. But as far as installing as long as the 64bit Win 8.1 disk has the UEFI boot files then it should be able to boot via UEFI (I know the downloaded disks for windows 8 originally had the issue of not having the UEFI boot files from experience I don't think windows 8.1 did).

    But as far as booting via UEFI depending on the UEFI firmware on your motherboard you may just need to set it to boot only to UEFI or UEFI first or just select it to boot via the UEFI region of the disk just depends on what settings it has available.
  4. When you say "My GPU supports an Hybrid BIOS" what do you mean? Bios is motherboard only. A 280X has drivers.

    It's just that we might be talking about different things.

    We're talking about Unified Extensible Firmware Interface (UEFI) - http://en.wikipedia.org/wiki/Unified_Extensible_Firmware_Interface

    - the interface between the OS (Windows mostly) and the motherboard bios (firmware)
