#/etc/init.d/vboxdrv setup Not Found - VirtualBox Fix!

When setting up Virtual Box I was faced with the immortal error telling me to run sudo /etc/init.d/vboxdrv setup. Simple enough, until you're told it doesn't exist.

Thus began my fight to get it working. The fix is here in the hope that it helps someone else.

To follow this guide you need to have a basic understanding of shell commands. If you don't, then just be careful.

First off I like aptitute so let's install it.
