Windows 7: Installed new HDD but cant install new Win7: Error Loading OS

Unplug all other HD's and peripherals,

Boot into BIOS setup, reset to defaults, save changes. (If an EFI BIOS you'll need to decide if you want UEFI BIOS vs. Legacy BIOS. If UEFI follow these special steps for Install, otherwise enable Legacy BIOS or Compatibility Support Module to proceed with normal install.) Set DVD drive first to boot, HD second, set SATA controller to AHCI, Save changes and Exit.

Then boot into Windows 7 installer DVD or flash stick burned or written using tool and latest ISO for your licensed OS version here.

At first installer screen Press Shift + F10, or enter System Recovery Options to open a Command Box, type:

DISKPART
LIST DISK
SELECT DISK 0 (after confirming Windows 7 target HD #)
CLEAN
CREATE PARTITION PRIMARY
FORMAT FS=NTFS LABEL="WINDOWS 7"
ACTIVE
EXIT
EXIT

Next click Install Now, then Custom install to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

In addition read over these steps to understand the tools and methods which work best to get and maintain a perfect Clean Reinstall - Factory OEM Windows 7. The steps are the same for retail.

After install you can adjust partition size or Create new partitions for data, etc. in Disk Mgmt. You are creating the partition here for the purpose of wiping the HD and marking Active which overcomes certain install failures.

Please mark this thread Unsolved at top since it shows no sign of being solved and having marked it thusly is driving away help you could be receiving.

If you knew that almost all Win7 sold on eBay if counterfeit, why did you buy it? I would myself immediately call MS Customer service to check the Product Key is genuine. If not file a refund with eBay and your bank immediately before its too late. I would do this on a parallel track to doing the install. If the steps above fail use the latest official installer provided as the disk may be tampered with.

If the HD is new, why don't they let the Windows 7 install run and do the HD stuff through the GUI?

I swear that is what I always do, and am reinstalling 7 again myself soon on a new SSD arriving supposedly today.

I have never used diskpart EVER and I've installed 7 at least 7 times on this rig over time.
I did all my partition stuff ahead though when necessary via an app like Active Partition Manager or Disk Management within 7, helps having a SATA docking station and SATA to USB adaptor though.
