I need to run MS Access but unfortunately it doesn't run well on WINE and the Linux version of it won't do the job either. So I need to run windows in a virtual machine.
I ran into a few problems when trying to run windows 7 64bit as a guest on Ubuntu 14.04 so I thought that I would share my findings.
My problem started by downloading the official version of VirtualBox. This might not have been a problem if I had known what other bits I needed to install but that is by the way. The best way to install it is using the package manager: e.g. Synaptic Package Manager.
More information on how to install VirtualBox can be found here: http://askubuntu.com/questions/187424/install-windows-7-through-virtual-box
