Hi Louie,
Thank you for the reply. Sorry for the delay.
As I understand, you want to downgrade to Windows 7 or re-install Windows 7. I am sorry to know that.
How did you purchase Windows 7, is it a retail copy or an OEM(came pre-installed) copy?
If you have installation disk, then you can refer to the section re-install Windows 7 and try to install it by going through the link below.
To get to Control Panel in Windows 8. Press Windows Logo Key+X. Then click on Control Panel.
Installing and reinstalling Windows:

If you are still unable to re-install Windows 7, then refer to the section" Using the Custom installation option and formatting the hard disk" in the above link.
Hope this helps in resolving the issue. If issue persists, do get back to us. We will be happy to assist you.
