Windows 7 Pro 64bit reinstallation problem: New system partition

Hello everyone!
I AM AWARE THAT A SIMILAR THREAD EXISTS ALREADY. HOWEVER MY CURRENT SITUATION IS RATHER UNIQUE AND UNLIKE ANY OTHER PROBLEM I HAVE FOUND ON ANY FORUM.
Recently I have been having some troubles with my computer. Basically it started with the missing operating system error. I went through a lot of work and effort before deciding that i was fine with simply reinstalling Windows 7. Upon launching the installation setup I was prompted with two options. Upgrade or Custom(Advanced). I wanted to completely start fresh so I chose Custom. They asked me to select a HDD to install the OS on. I selected my 1tb Western Digital black hard disk, knowing that I had done this before and it had worked. When I hit "next" it told me that " Setup was unable to create a new system partition or locate and existing one". I went to Disk options and deleted any partition I may have had. I tried again, same error. I switched HDDs using an identical HDD.( one of them is faulty so i tried both to be sure) but the error was still there. So what do i do? How can I fix the problem and proceed with installing Win7? Note: I currently cannot access this computer since the OS is missing. Also my only other computer is a Mac.

Unplug all other HD's and peripherals, Boot into BIOS setup to see if there is an EFI Boot Disk in BIOS Boot order. If so remove it, set DVD drive first to boot. If EFI BIOS also set to Legacy BIOS.

Then boot into installer, at first screen Press Shift + F10 to open a Command Box, type:

DISKPART
LIST DISK
SEL DIS 0 (after confirming Win7 target HD)
CLEAN
CREATE PARTITION PRIMARY SIZE=102400
FORMAT FS=NTFS LABEL="WINDOWS 7"
ACTIVE
EXIT

Now click Install Now to Clean Install Windows 7 to partition you created.

If this is preinstalled Win7 also read over these steps to Clean Reinstall - Factory OEM Windows 7 to assure you get a perfect reinstall.
