I have a question in regarding to installing Windows 8 in Full UEFI and not legacy mode.

First off, the DVD rom drive does not show up as UEFI.
Also my Kingston SSD drive does not show up as UEFI.

To install Windows 8 in full UEFI Mode onto the SSD, does the SSD have to show in the boot options as UEFI:Kingston, VR300 or whatever the actual label is?

You'll have to clean install for UEFI, I would also suggest converting your DVD to USB Flash drive. Set the system for UEFI booting, boot from the USB flash drive or DVD, if your SSD has already been used, delete all the partitions & create a new one. In my case when I created a new partition it automatically created 4 partitions. If this is a new SSD then create a new partition and see if yours also creates 4 partitions automatically. Install & you should be set, providing your mobo can do UEFI booting.

Edit: I stand corrected. It created 3 partitions. #1 is 300mb for recovery, #2 is 100mb for EFI system partition, and the last is 237.96mb for the OS.

RealBeast, I have an MSI Z87 G45 Gaming with the latest BIOS update.
I currently already have Windows 8.1 installed on it but in mixed mode. I want to reinstall in UEFI mode so that I can enable Secureboot.

Since the DVD rom drive is I guess not compatible with UEFI, I have created a USB thumbdrive to install Windows 8 and it does show as UEFI in the boot options.

I'm just wondering if the SSD also has to show up in the boot options as UEFI.

Yes, the SSD will work, but you will need to unpartition the SSD as the first step in the install process since it is currently an MBR formatted drive and needs to be GPT to support a UEFI install. Look at THIS.

Okay thanks. I was just wondering because my Western Digital USB 3.0 backup drive shows in the boot options as UEFI: Western Digital or something like that and is partitioned with an MBR partition.

Anyhow, I did as said and installed with the USB and did the custom installation and deleted the old partitions and Windows created the three partitons that are necessary.

It booted up quickly with the SSD before switching to the UEFI installation but now with the UEFI installation (even without fast boot enabled) it boots up even quicker.
