cannot install hyper-v

Hello everyone,

I would like to enable Hyper-V on my windows 8 laptop (Acer Aspire E1-430P) , to practise at home.

I looked on the internet how to enable it but when I tried it I got stuck.

When i am in the control panel "turn Windows features on or of" I should be able to add Hyper-V.

Unfortunattely Hyper-V is not in that list. 

Does anyone know what to do now to enable hyper-v?
