I am running Ubuntu 12.04 on an ASUS U31S with a Samsung external DVD.

I am trying to install virtual box to run windows 7 (yes i have a license)

However, when I start the windows install it says:

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 the kernel module by executing

'/etc/init.d/vboxdrv setup'

as root. If it is available in your distribution, you should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary.

Then when installing windows it says

"device drivers are missing"

When I browse either the windows disk or the dvd rom disk it says it finds nothing.

Any suggestions?
