Installing Windows Server 2008 R2 On Gpt Disk

I recently purchased a new Samsung 840 EVO with a few other components, to rebuild a machine that has been on the verge of extinction. With the SSD purchase, I also purchased a new motherboard from Gigabyte. Games At Jeff Wu.net more.

I am still running my optical drive from a external USB port, and loaded that in UFEI mode because of the GPT partition on the SSD. Windows Server 2008 (not R2) goes through the general install process just fine, but when it hits the first reboot stage it comes back as if nothing has been installed and wants to start the process over, however, there is only the one partition still and it looks like data has been written to it, but when it tries to boot from the SSD it's not detecting an OS. I have tried the Shift- F10 trick but that doesn't really do anything. I've loaded the command prompt from the repair windows options, to try and run diskpart from there to clean the disk, but I keep getting an error saying no disk selected, tried selecting disk 0, still nothing.
