Has there been any attempt to run the Recovery Partition?
Look on the first boot screen for the key(s) to press to start Recovery.
If it isn't there, then read the Manual at the Asus Support Downloads webpage for your model to find out how to run Recovery.
Or call Tech support which will walk you through it for free if you are within a year of purchase.
To answer the question posed by your post title: most tech enthusiasts locate a copy of the Win7 installer for their version (all versions can be unlocked if needed) to reinstall with the Product Key stickered to the machine. This avoids the factory bloatware on the Recovery partition. The retail and OEM installers have been the same since Vista.
If you can't use a DVD: extract the ISO using ImgBurn, unlock all versions using ei.cfg removal tool, then write to USB flash stick. USB Windows 7 Installation Key Drive - Create or Windows 7 USB/DVD Download Tool
