For OEM ask your vendor support services. There are generally more options, namely set of DVD with Windows installation media and applications DVD, or special DVD with full installation (recovery).

Hi,

I just make a supplement, if your prodcut key was a retailed key, you can run Windows 8.1 upgrade assistant tool on other Windows 7, 8 system, type the produt key to download the ISO file, then choose to create a installation dic to install Windows 8.1 on your com

Hi, Vivek,

The content of the link Milos provided has a bit of problem with Windows 7 ISO installation disc creation. But its Windows 8, 8.1 content still helpful to create a Windows 8.1 Installation disc.
