I want to enable Hyper-V in Windows Features, but there is no Hyper-V option
You will need the pro version to get the hyper-v feature.You can read here for more help as well: http://technet.microsoft.com/en-us/library/hh857623.aspx
If someone is having this problem of missing tickbox on Windows 7 Pro, it can be solved by installing
Remote Server Administration Tools for Windows 7 with Service Pack 1 (SP1).
Only problem your Hyper-V is not running is because you Don't have the Windows 8 Pro version of the window. So get that first.
