Setup can't create system partition

Hello everyone,

A few days ago i decided on completely reinstalling everything on my computer, but as you can see in the title, i have a problem within the installation of Windows 7. Everytime i try to install it from my USB Flash Drive, i manage to get as far to select wether to upgrade or custom. I pick custom, as all old files have been wiped, but upon selecting my drive to install it on, it gives the error of not being able to create a system partition, and is unable to find an existing one. This happens both when ive created a new partition and formatted it, and when i leave the drive on unallocated space(preffered method)

All other hard drives have been unplugged, and im installing from an USB 3.0 flash drive in a 2.0 port, and all excessive USB devices have been pulled as well.

Ive tried using a method through diskpart, but that failed.

DiskPart <ENTER>
list disk <ENTER>
select disk 0 <ENTER>
clean <ENTER>
create partition primary align=1024 <ENTER>
format fs=ntfs <ENTER> (Will Take a While)
assign <ENTER>
active <ENTER>
exit <ENTER>
exit <ENTER>

Work through these steps to Troubleshoot Windows 7 Installation Failures - Windows 7 Help Forums

Once it gets going then look over the steps to get and keep a perfect Clean Reinstall Windows 7.

Thanks for the help, but sadly, the error still remains. It still fails to create or find an existing system partition

Then where do you get the error when running the Diskpart commands? Be specific.

Next test the hard drive with the maker's HD Diagnostic
extended CD scan to know for certain its condition.

No no, the diskpart commands are all working, but upon reinstalling windows it fails, where you have to select where to install it.

*edit: i had already scanned with HDtune pro, and the device is looking fine, nothing out of the ordinary

How did you determine if you have a UEFI BIOS or not? Is there a boot choice for UEFI when you boot flash stick?

How did you create the flash stick and what was the source of the ISO. Confirm the ISO and try writing a new stick from Step 1 of Clean Reinstall Windows 7

Motherboards manufacturer page, Motherboards - F1A55-M - ASUS
It states it has UEFI BIOS, no choice to boot as UEFI however, upon hitting f8 (boot location select) it just prompts for location.

I created the USB using the recommended program rufus on here, as for the .ISO, i cant remember. theyre long standing .ISO's i havent had problems with before.

Then this is where the problem lies.

Boot the stick using the one-time BIOS Boot menu key. Is there a choice for UEFI flash stick? If not then the stick is not formatted correctly or the BIOS settings are awry.

Boot into BIOS setup to report back all settings choices for UEFI, CSM, Legacy BIOS, BIOS Boot Priority order.

Confirm that the stick maintained the settings in Option One of UEFI Bootable USB Flash Drive - Create in Windows
after you added the ISO, since these can jump around then.

i noticed the settings jump when selecting an ISO in rufus, and i accounted for that.
As for the BIOS settings, i can only give you the boot order, as i cant find the other settings. (probably there, but i dont see them)
boot option priorities: (listed as named in BIOS)
1. P5: WDC WD5000AAKX-003CAO (my HDD)
2. P4: TSSTcorp CDDVDW SH-222BB (Optical drive)
3. Disabled
