Hi, thanks for using JustAnswer.com I am Cris.
Just to clarify you are try to reinstall Windows 7 from the backup partition, is that correct?
How are you trying to reinstall from a Windows 7 reinstallation disc?
OK, neither the drivers or reinstall partition are needed to reinstall Windows back onto your PC. The reinstall partition is there to make it easy for someone to reinstall w/o any discs. You can complete the install and the laptop should have a Microsoft sticker located on the backside or behind the battery stating the product key. However the product key will only work if it is the exact same version of the operating system you are installing.
Example: You have a product key for Windows 7 Home Premium but you have a reinstall disc for Windows 7 Pro. Both the key and version you are installing have to match.
Once installed you can finish the setup of Windows and install any drivers you need from the gateway site. All PC manufacturers have drivers on their site by looking up the model number.
