Windows 10: Product key issue within the same device after a new OS install.

Background Info:I have a HP Compaq nc6400 that was previously running Windows 7 Pro Service Pack One. I haven't used this laptop for a year because it was previously damaged and I've been repairing it myself. Yesterday after managing to resolve the issue within my laptop, I managed to access the ADMIN user which contain the ability to upgrade Windows 7 to Windows 10. Before this ADMIN account wasn't accessible because of a forgotten password, however I managed to find a booklet of old passwords and was able to open this account. Previously, my account wasn't able to upgrade to Windows 7 to Win

Cannot upgrade to Windows 10 - Unique Product Key situation

No... let me try again.

• Old computer is running Win7 Pro (SP1) with a Product key I have from a few years ago. The Product is activated already, but I do NOT use this computer at this point, so I didn't worry about using the Product key when moving to the new computer (see below).
  
• New computer is running Win10 Pro, with data and OS migrated from the Old computer, (same Product key as above), then Upgraded to Win10 (without getting a new Product Key).

What I am trying to do now...

• I want to upgrade the OLD computer (Win7 Pro) to Windows 10... using a new Product Key I just purchased.
• I have tried to do this internally, and also using the ISO burned to a thumb drive. But it does not want to work.
• Steps:
  • Start from USB drive.
  • Enter New Product Key (or click "I don't have one").
  • Install initiates and then tells me to restart from Windows and then open the installer again to continue.
    • At this point, I actually need to Quit the installation to restart the machine.
  • When restarted, I go to the USB drive and restart/resume the installation process.
  • I have tried to download and not to download updates, but when the installation fails, I see the message, "Something happened" and "Setup has failed to validate the product key".
  • NOTE This happens if I enter the NEW Windows 10 Product Key, or if I skip that step (which I assume means that it will use the old Windows 7 Key for the upgrade).
