Check  Virtualization  status under performance option in your task manager  If you already have enabled it in your BIOS and still status is  Disabled   then go to bios  disable it and save  amp  exit  Restart or shut down again  Enable it in BIOS again and save  amp  exit  This time you ll see the status changed to  Enabled   It took me 3 attempts  don t know why it took that much time  but finally it worked

Just to make it simple  The solution is just to enable vt-x or Virtualization Technology in bios  which is under Advanced Tab   and once it s enabled  the error disappears   FYI I had similar issues starting up my Android emulators in Appium studio for my mobile testing  and on top  I had latest bios  which looked so different to the standard one  So attaching screenshot of my computer bios  but the option should be there on any Bios settings   Just need to boot the computer  and push Esc or some function key to see the computer bios  and then find the correct option to enable it under Advanced Tab   most importantly  you may have to scroll down as the option would be down the list  I left my Hyper-V feature as is  which was enabled though
