VirtualBox does not come with an Operating System. You will have to provide the Win7-64 installation media and do the installation of Windows in a Virtual Machine (VM). Then install your database.

You sound like a fairly new user to VirtualBox. Since you are expected to know some basic terms before we engage in a meaningful discussion, I would suggest to start by reading three small chapters from the User Manual:

• 1.2. Some terminology,
• 1.7. Creating your first virtual machine and
• 1.8. Running your virtual machine.

I assume you mean that you downloaded a VirtualBox VM containing Windows 7.

Where did you download this from?
