Windows 8/10 has some Problems with Intel HAXM Installation.

Intel HAXM is official supported with this Operating Systems:

• Windows 10 (32/64-bit)
• Windows 8 (32/64-bit)
• Windows 7 (32/64-bit)
• Windows Vista (32/64-bit)
• Windows XP (32-bit only)
• OS X 10.6 or 10.7 (32/64-bit)

But on Windows 8/10 it should work too except of some issues you will see later.

If you get this picture on installing Intel HAXM

even you have a supported CPU on Windows 8/10 there are severals issues who can cause this:

• Bios Setting Intel Virtualization
  Check if in the BIOS Setting the Intel Virtualization is on.
  Should be locatet under the CPU Setting.
  On a MSI Motherboard is is under “Overclocking Setting” and “CPU Features“.
  
• Hyper-V is installed and activated
  If Hyper-V is installed and activated it conflicts with the Intel HAXM drive and you get the error above.
  
  • You can try to set the Hyper-V off with bcdedit like in this post
    “How to install Intel HAXM after installing Hyper-V“
  • If you don’t need the Hyper-V it is better to uninstall it
    • ControlCenter – Programs – Turn Windows features on or off
      
    • Check off the Hyper-V
      
• Avast 8 installed
  If you have Avast 8 installed the Intel HAXM does not work in Windows 8
  I have already submitted a ticket to Avast for this problem.
  Until this is solved you can use Avast 7 or any other Antivirus program.UPDATE 10.04.2013
  The problem seems fixed with the newest Avast 8 BETA
  Download
  
• Avast 2015 installed
  Avast 2015 under Settings tab > Troubleshooting, you should uncheck “Enable Hardware-assisted Virtualization” and reboot!
  If this is enabled the Intel Vt-X Virtualisation isn’t working!!
