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? –  Sathya Feb 16 '13 at 10:03

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? –  user1774180 Feb 13 '13 at 10:19
    
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. –  Александр Киричек Feb 13 '13 at 11:46
    
:i will select second way –  user1774180 Feb 13 '13 at 12:29

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
