This will work, although you will not have UEFI, I'm not seeing advantage of it.
1. Turn off UEFI and set drive to IDE mode
2. Download DOS version of free Active@ KillDisk
to write all 0s to drive. That should take care of GPT partition table. You might have Acronis or other tool that will do the same.
3. Set drive to AHCI mode
4. Boot with Win 7 disc and create partition with its setup.
Note that you might have no problem with UEFI and MBR partitioning system, but I think at this point you'll rather have it working than fight with UEFI.
