I am using Ubuntu 14.04 and have installed windows 7 using virtual box. After Ubuntu update, when I try to power on windows 7, the following error message comes:
Failed to open a session for the virtual machine Windows 7 x64.
The virtual machine 'Windows 7 x64' has terminated unexpectedly during startup with exit code 1 (0x1).
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: Machine

I have tried the following and its still not working
sudo apt-get install linux-headers-generic build-essential dkms
sudo apt-get remove --purge virtualbox-dkms
sudo apt-get install virtualbox-dkms
It shows a dependency error when installing virtualbox-dkms
The following packages have unmet dependencies:
virtualbox-dkms : Depends: virtualbox (>= 4.3.10-dfsg-1)
