There are a few possible reasons why it would not show up.
The first and most likely is: The network adapter has been disabled in the BIOS settings.
Reboot your computer and press F10 when it first shows anything on the screen. Go into networking and make sure the ethernet adapter is enabled.
The other reason it could be missing is you have a motherboard problem.
My first thoughts are the BIOS issue.
Hope this helps,
