Hi,
As you have installed a retail version of Windows 8.1 the restore partition that was on the hard drive wont work. You have to manually reinstall Windows using the reinstallation DVD that came with the system. If you have the DVD, please follow the steps suggested in http://dell.to/1bOvoee.
In case you dont have the media, please send me a private message with the system service tag and the result, I would be happy to check the warranty details and help you with the options available.
