I am a little fuzzy on what's happening here. Is the HDD detected in BIOS?
Win 8 supports UEFI. So disable legacy boot, enable secure boot, enable fast boot.
Load or insert DVD or USB stick.
Reboot and tap "ESC". Select "Boot Menu".
Select UEFI boot device, either DVD or USB.
You should be able to run UEFI-GPT setup now.

Tap "ESC" at boot. Select "Setup" from menu.
Navigate to storage or devices in BIOS.
Do you see the HDD?
If the HDD is detected in BIOS it should be available as a legacy or EFI device when installing Windows. An MBR vs GPT install is determined on whether you boot to the install media using UEFI or legacy boot option.
How did you create the USB media? You may have set the USB stick as MBR only. So it will not appear as a bootable UEFI device in the boot menu.
If you want GPT you must select the bootable Windows 8 media under UEFI boot devices when in the boot menu.
I have installed Win 7, 8, 8.1, and Win 10 many times using GPT and have never seen what you are describing.
Can't help any further. Maybe another forum member has additional thoughts.

I created a GPT Win 7 USB stick as follows:
Converted Win 7 DVD to ISO using Cyberlink Power2Go.
Used Rufus to create a bootable Win 7 USB stick. You have to change the bootable partition scheme from MBR to GPT before creating the USB stick.

It must be something with your BIOS.
I have installed new HDD's cloned HDD's to SSD's on many occasions. Never had a problem with using GPT on any of the new drives.
Again, I have never seen what is happening to you.
