FINALLY!!! EDIT: Actually this was only a temporary fix
Here's the *TEMPORARY* SOLUTION for anyone who has the same problem:
Someone on another forum told me to download Ubuntu OS from Linux to a flash drive using Rufus, just like I did with Windows. Plug and boot form the flash drive as if you want to install Ubuntu. It will give you the option of trying Ubuntu without installing. Select that it will eventually load up Ubuntu. Ubuntu could find my HDD with no problem. I formatted the HDD using NTFS by following this guide. Then I removed the partitions (I don't know if that was necessary). I put in the flash drive with Windows 10 Installer on it and it FINALLY recognized the hard drive. But it gave me some error saying "Windows Cannot be installed to this disk the selected disk is of the GPT partition". I pressed Shift + F10 --> opens command prompt --> type "diskpart" [enter] --> type "list disk" [enter] --> take note of which disk # is your HDD, it will probably be 0 --> type "select disk #" [enter] and replace with whatever number the HDD is --> type "clean" [enter] --> close command prompt. Click the back tab to go back to the beginning of the Installer and it will show your drive will pop up.
I think when I early terminated the Windows 7 installation, it did something to the HDD which prevented Windows Installers from being able to "see" it.
