I'm getting this error while loading a Puppet image from a Oracle virtual box. How can I fix it?

Failed to open a session for the virtual machine learn-puppet-centos-6.4-pe-3.1.0.

VT-x is disabled in the BIOS. (VERR_VMX_MSR_VMXON_DISABLED).

Result Code: E_FAIL (0x80004005)
Component: Console
Interface: IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}

In addition, I see that the acellerate-tab in Virtual Box is disabled.

Recently I had this same problem on windows 10 - after installing Hyper-V & other windows features like:

Windows Projected File System, Windows Sandbox, Windows Subsystem for Linux, Work Folders Client,

And it stopped working for me;(

  1. Step uninstall Hyper-V -check if ti stared to work for you - no in my case
  2. Step uninstall other windows features mentioned above! - I worked for me;) enter image description here
