Kernel driver not installed (rc=-1908) when running Windows 10 VM

I'm trying to install a Windows 10 VM on Oracle VM VirtualBox ver. 5.1.22 on Ubuntu 17.04, but whenever I try to run it, I get the following errors:

The virtual machine 'Windows 10' has terminated unexpectedly during startup with exit code 1 (0x1).

Result Code:
NS_ERROR_FAILURE (0x80004005)
Component:
MachineWrap
Interface:
IMachine {b2547866-a0a1-4391-8b86-6952d82efaa0}

And:

Kernel driver not installed (rc=-1908)

The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall virtualbox-dkms package and load the kernel module by executing

'modprobe vboxdrv'

as root.

where: suplibOsInit

what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - The support driver is not installed. On linux, open returned ENOENT.

I'm almost completely new to Linux and Ubuntu so please try to be simple.

After struggling with the same issue all night I finally found a way to keep Secure Boot enabled & got Virtualbox VMs running properly- in Ubuntu Xenial (16.04.3).

I used ppa:costamagnagianfranco/virtualbox-ppa. Though maybe another one would work - possibly even the official one - I didn't try.

A key part of the process was signing the kernel module, and these instructions worked for me.
