HDD is not recognized by Bios and Windows

Okay at first it could sound very simple on how to fix it but it's a bit more complicated than that so please hear me out
First of all im very new to this so forgive me if I posted this in the wrong section.
Okay so went shopping and asked some computer technicians to build me a computer and all now that I'm trying to install windows 7 32 bit ( or 64 bit) when i get to the part " where do you want to install windows 7 "
i see this : Disk 0 unallocated space 3.9 GB
okay now the thing is there are 10000 of threads like mine but the difference here is that i have a 500gb hardrive , why on earth is only showing this one with only 3.9 GB ?!?!?
there are no more partitions and all the options such as " delete , format , etend and so on are disabled ,
only " New" is available which whatever i try prompts with an error and cant change anything,
i checked my BIOS ( now im a bit noob ) and on SATA settings the only thing i could find was my Optical Drive i couldn't find my hardrive listed there
now i've tried IDE, ACHI as well same thing.
Please help me out here
here is some spec details on what I'm using :
Motherboard : Asus Mainboard INTEL S1155 H61 P8H61 B3
Memory : 2x 4GB Ram DDR3 PC1333
> HARD DRIVE > : Seagate HDD Desktop SATA III SV35 500GB 7200RPM 32MB
Graphic Card: SAPPHIRE VGA PCIE ATI 7850 2GB DDR5 256BIT
CPU: Intel processor S115 CORE i5 2500k 3.30ghz

Any help would be appreciated
UPDATE: This is an absolute raw harddrive installing an operating system on it for the first time

Hello Raeion. Welcome to the forum.

When the hard drive is not recognized in the BIOS it means that either the drive is defective or there is a connectivity problem.

The first thing to double check is connectivity. This is how I would proceed:
(Please use proper static precautions!)
  • Disconnect the hard drive (I assume there is just one) - power and data cables.
  • Boot the machine and go into the BIOS settings > set SATA mode to AHCI and leave it there.
  • Reboot the machine, check the BIOS again. Should be in AHCI mode and you should see the DVD drive listed on it's port.
  • Shut down and carefully connect the hard drive again. Recheck the data cable connection to the motherboard.
  • Start up, go into BIOS settings and see if the hard drive is listed (when you start up, listen for the drive to spin up)
  • If not listed, shut down and try a different SATA port on the motherboard
  • If still not recognized, try a different data cable (the one on the DVD drive is known good).
Let us know what you find.

EDIT:
If you had this machine built for you then you may want to just take it back and get the technicians to fix the issue. Don't leave the store until you can see the drive recognized in BIOS.
If you were to damage something doing your own work you might void any warranty.
