I bought Windows 8.1 pro so I could use the Hyper-V Virtualisation.
I have the correct Hardware
- Intel(R) Core(TM) i5-4200M CPU @ 2.5GHZ
- Toshiba C55-A-1N1.
In TaskManager->Performance it says
Virtualisation: Disabled
Hyper-V support: Yes
In Turn Windows features on or off Window for Hyper-V it says
Hyper-V - ticked with a square tick(Partial tick)
Hyper-V Management Tools - ticked
Hyper-V GUI Management Tools - ticked
Hyper-V Module for Windows PowerShell
- ticked.
Hyper-V Platform - not able to tick (greyed out)
Hyper-V manager opens but I cannot create a Virtual Machine.
The laptop manufacture Toshiba have assured me that the laptop has the
capability and it is a Microsoft problem.
I spent 4+ hours getting bounced around Microsoft tele-operators/technicians
repeating the same problem to each. I am now waiting on a call back I was
promised two days ago. I am starting to think there is a known problem that
no-body want to admit.
So the question is.
1. Does anyone know how to fix this? or
2. Is anyone aware of a bug in Windows 8.1 Pro resulting in Hyper-V not working?

This is the message I get from hovering over the greyed out checkbox Hyper-V Platform in Windows Features.
"Hyper-V cannot be installed: Virtuallisation support is disabled in the firmware."
This could mean Toshiba has turned it off for security or something.
The output from coreinfo does not mention EPT, see below.

Hovering over the disabled "Hyper-V Platform" option should give you a hint on why it is disabled:
Here are few things I would check:
- Make sure that the Hardware-assisted virtualization is enabled in the BIOS.
- Make sure Data Execution Prevention (DEP) is enabled in BIOS.
- Make sure your processor is 64 bit and has Second Level Address Translation (SLAT) capabilities. And then confirm SLAT is enabled in BIOS.
You can use Sysinternal's CoreInfo.exe to determine if your machine supports Virtualization and SLAT. Tool can be downloaded from Microsoft Technet site: http://download.sysinternals.com/files/Coreinfo.zip
Run "CoreInfo.exe -v" from elevated command prompt.

HYPERVISOR - Hypervisor is present

EPT * Supports Intel extended page tables (SLAT)
If you see "-" here, it means your processor does NOT support SLAT; if it is a "*", then it supports SLAT. You should ideally see the output as above before enabling Hyper-V.
