Call Asus and give them the serial number of the laptop. If you can't get in with Support, try calling Sales. Basically, you can purchase the reload media from them. It's cheap, usually $10-20 + the cost of shipping. I've done this with nearly every brand, although never with Asus I will admit.
If that doesn't work, I typed in "windows asus" on everyone's favorite Torrent site and a few results came up. Downloading those aren't actually illegal since they are authenticating off the key embedded in your hardware. Unfortunately, I only saw results for Windows 7 (not 8.1.)
