Vagrant up: Fails at Booting VM

I am having trouble running the vagrant up command, has anyone else had this issue.

Bringing machine 'mongod-m103' up with 'virtualbox' provider...
==> mongod-m103: Clearing any previously set forwarded ports...
==> mongod-m103: Clearing any previously set network interfaces...
==> mongod-m103: Preparing network interfaces based on configurati``on...
    mongod-m103: Adapter 1: nat

    mongod-m103: 22 (guest) => 2222 (host) (adapter 1)
==> mongod-m103: Running 'pre-boot' VM customizations...
==> mongod-m103: Booting VM...
There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

Command: ["startvm", "fccb517e-76ed-4844-8d2f-d25402fd9a15", "--type", "headless"]

Stderr: VBoxManage.exe: error: VT-x is disabled in the BIOS for all CPU modes (VERR_VMX_MSR_ALL_VMX_DISABLED)
VBoxManage.exe: error: Details: code E_FAIL (0x80004005), component ConsoleWrap, interface IConsole
