I found the answer and like to share with you .

1.Enable Virtualization during your BIOS time

2.Disable the Hyper-V role through Settings(problem faced by me)

a)Right click on the Windows button and select ‘Apps and Features’.

b)Select Programs and Features on the right under related settings.

c)Select Turn Windows Features on or off.

d)Select Hyper-V and disable it

Stop hyper-v service running by default in Windows 8/10, since it blocks all other calls to VT hardware.

Additional explanation here: https://social.technet.microsoft.com/Forums/windows/en-US/118561b9-7155-46e3-a874-6a38b35c67fd/hyperv-disables-vtx-for-other-hypervisors?forum=w8itprogeneral

Also as you have mentioned, if not already enabled, turn on Intel VT virtualization in BIOS settings and restart the machine.

To turn Hypervisor off, run this from Command Prompt (Admin) (Windows+X):

bcdedit /set hypervisorlaunchtype off
and reboot your computer. To turn it back on again, run:

bcdedit /set hypervisorlaunchtype on
If you receive “The integer data is not valid as specified”, try:

bcdedit /set hypervisorlaunchtype auto

To turn Hypervisor off on windows from a command window: “bcdedit /set hypervisorlaunchtype off” and reboot. To turn it back on: “bcdedit /set hypervisorlaunchtype on” (or auto start) and reboot. –

@TjKellie your advice worked for me, thanks. Perhaps you’d like to edit your commend and add to it that the user should be an admin in order to perform that command.  –

Woooow, thanks so much for this. I was fighting with this for a few hours, and I thought it was because I was running Windows 10 on a MacBook Pro. It was just because hyper-v was enabled. (Side note: it’s strange that Docker and VirtualBox can’t work at the same time.) –

To turn it back on, its “bcdedit /set hypervisorlaunchtype auto”, not as mentioned by @TjKellie –
