VirtualBox crashes when starting a just defined OS

[John Rose]

VirtualBox crashes (screenshot attached) when starting a just defined OS (Windows 7 32-bit) before 'loading' the Windows 7 iso image to install Windows 7.

virtualbox-dkms package is installed. mdoprobe of vboxdrv gives:
john@NewLaptop:~$ sudo modprobe vboxdrv
[sudo] password for john:
modprobe: ERROR: could not insert 'vboxdrv': Required key not available

Hi, please try apt-get install --reinstall virtualbox-dkms, but it seems to be bug #1574300
