When I run Windows Phone 8 emulator first time this error is shown

Can't Start Windows Phone Emulator

enter image description here

My system is a Lenovo, with an Intel Core i5-3470s running on Win 8 Enterprise. SLAT Status check shows following:

You have a SLAT capable machine, but hardware virtualization is disabled at BIOS level, so please enable it.

CoreInfo shows:

  • AMD A10-4600M APU with Radeon HD Graphics
  • AMD64 Family 21 Model 16 Stepping 1, Authentic AMD HYPERVISOR
  • - Hypervisor is present SVM
  • * Supports AMD hardware-assisted virtualization NP
  • * Supports AMD nested page tables (SLAT)
  • (- indicates not present, * indicates present)

How do I enable hardware virtualization? I find nothing in the bios to enable SLAT.

  • You say you have Intel Core i5-3470s, yet Core info says otherwise. So which one is it?

As mentioned in this MSDN article

To enable BIOS settings required by Hyper-V

  • Restart your computer and press the key required to enter the BIOS settings.

    You can view and change your computer’s BIOS settings by pressing a specific key during computer startup. The key to press varies depending on the manufacturer. It is typically a special key such as Del or a function key such as F2 or F10.

    • Enable the following items if they are available

    enter image description here

    • Disable the following items if they are available:

      • Intel VT-d

      • Trusted Execution

    • Save the settings and restart the computer again.

    • Next, enable Hyper-V in Windows.

I hope it helps.

  • thanks but when i am enter in BIOS at that time there is no option for harsware-assisted virtualization for intel so how can i enable it?

  • I think the now it only 2 way to find the solution. 1. Contact LENOVO support download.lenovo.com/express/supportphonelist.html and ask them where you can find needed option. 2. Take fotos of BIOS settings pages. So we can find what options you need to enable.

You can try to flash the BIOS to the latest version - http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS029433

but I remember that a clleague of mien could never get it work on the same model. He ended up following my tutorial for using the emulator within VMWare:

Install VMWare Workstation v9 on your host OS
Install Windows 8 64-bit as a guest OS
Enable virtualization in Hardware → Processors and select these settings:
    preferred mode: Intel VT-x/EPT
    virtualized Intel Vt-X - selected

enter image description here

The rest is unchecked.

This will allow you to run the Windows 8 SDK/emulator in the VMWare instance without having to deal with the BIOS settings
