Getting error when starting virtualbox

I installed whonix to virtualbox, but when I start it, the window closes and gives me an error:

Failed to open a session for the virtual machine Whonix-Gateway-XFCE.

Not in a hypervisor partition (HVP=0) (VERR_NEM_NOT_AVAILABLE).

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

Result Code: E_FAIL (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

I have enabled virtualisation and this error still persists. Can someone help me with this please?
