I have looked in a variety of places for a solution and am only posting as a last resort. If this is a redundant post I apologize in advance.

I am running Ubuntu 12.10 "Chrubuntu" on an Acer C7 and I have had a hard time trying to get Windows 7 installed in Virturalbox.
Whenever I try to start the VM i get the error:
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.

I have tried a number of ways to fix this problem including:
sudo apt-get install linux-headers-3.5.0-17-generic
sudo apt-get remove virtualbox-dkms - gives me the error E: Unable to locate package virtualbox-dkm
sudo apt-get install virtualbox-dkms

does anyone know if I will be able to install virturalbox? I would like to uninstall it and start all over trying to get it to work but i'm not really sure how to do that.
any help is appreciated, thanks
