I completed the installation of Oracle's VirtualBox using the delivered Wizard. The process appears to work successfully after answering the memory and storage questions. When I activate the Virtual Box, I receive the message "Fatal: No Bootable Medium".
I tried searching the error message and receive 187 postings dealing with Fatal: No Bootable Medium". How does one decipher 187 potential solutions?
NOTE: I want to use the Virtual Box on my Oracle Laptop for self-training of PeopleSoft 9.2. Oracle does not provide Windows 7 CD's when a Laptop is imaged.
Can someone provide guidance how to proceed?

There is only one solution: attach a bootable medium to the VM.

The procedure you describe is the first step of creating a VM - this does not install an operating system. All you have created is a hardware simulation, a blank PC. If you want that simulation to run a particular operating system (OS) then you must install that OS yourself. To do so you must also provide an OS setup disk, ideally as an ISO (none are bundled with VirtualBox), but a physical CD can also work. You install the OS into the VM like you would on a physical PC.

When you create a VirtualBox VM you are asked to choose from Linux, XP, Win7 etc: this doesn't mean that VBox bundles those operating systems, it only means that the VM "hardware" will meet the requirements of that OS.
