I’m glad you enjoy this website! 🙂
About the hibernation problem:
– First of all remember that you can’t use hibernation if you are using Hyper-V in the x64 edition of Windows Server 2008.
– I don’t know how to add the Hibernate option to the start menu, but first try if hibernation works by running shutdown -h in the Command Prompt (Start -> Run -> cmd.exe).
If that works you can add a shortcut with that command as workaround till someone finds the solution for this problem.
Good luck! 😉
