Kernel VirtualBox não carregado

Question

Ubuntu 16.04 LTS e VirtualBox 5.1.8

Gostaria de criar algumas máquinas virtuais, mas o Virtual Box apresenta essa mensagem de erro quando a inicio:

WARNING: The vboxdrv kernel module is not loaded. Either there is no module
     available for the current kernel (4.4.0-45-generic) or it failed to
     load. Please recompile the kernel module and install it by

    sudo /sbin/vboxconfig

    You will not be able to start VMs until this problem is fixed.

E então eu corro sudo /sbin/vboxconfig . Saída:

vboxdrv.sh: Building VirtualBox kernel modules.
vboxdrv.sh: Starting VirtualBox services.
vboxdrv.sh: Building VirtualBox kernel modules.
vboxdrv.sh: failed: modprobe vboxdrv failed. Please use 'dmesg' to find   out why.
There were problems setting up VirtualBox.  To re-start the set-up process, run
/sbin/vboxconfig
as root.

Mensagens selecionadas como erros em dmesg :

Desative inicialização segura no BIOS. Pelo menos funcionou para mim
