W7 won't install on partition. Disk drive partition problems

Hi,
MSDN member.
Primary OS is Windows 8.1 but I need to install a Windows 7 partition for testing. I've followed threads dealing with others also having problems but they've not solved mine.
I've several SATA and one SSD HDD. Windows 8.1 is installed on SSD. I'm trying to install W7 + update 1 from msdn supplied ISO burned to DVD onto an empty 2TB HDD. I've unplugged a couple of USB flash drives. Checked that AHPI (or whatever it's called) for my SATA drives is turned on. Had safe boot off and on. Checked it's MBR partition and not GPT. I've also run through the installation problems thread.
When I get to the pictured screen, I select the empty disk and attempt to set it up but nothing happens when I press Apply and I get the following message when I press the next button. I've never had problems like this before and don't know what else I can try to fix it.

If the 2TB drive is empty (not used) then delete all the partitions until it's just unallocated space, then click Next to start the install. The installer will create the partitions it needs then do the install.

In addition to disabling Secure Boot in BIOS setup in order to install WIn7 at all, you'll need to enable CSM, Compatiblity Mode, Legacy BIOS and Legacy Boot to install Win7 to an MBR formatted disk. These settings are named differently in different BIOS. If you are in doubt or have continued problems, posting back camera snaps of all UEFI related settings choices will help. Attach using paper clip icon in reply box.

Otherwise you'll need to install Win7 to UEFI which will format disk GPT once DVD is booted as a UEFI device and all partitions are deleted. UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums
