Try Out a New Operating System the Easy Way with VirtualBox

Frustrated with seeing all the new wonderful looking Windows 7 and Linux systems and having no easy way to try them? Now you can enjoy all the new operating system goodness in a virtual environment with VirtualBox. VirtualBox works on Windows, Linux, Macintosh and OpenSolaris.

Note: The version of VirtualBox shown in this article is Beta 2 running on Vista SP2.


The installation runs the same as for other software, but with the third window you will find that you can choose what features you would like to install. It is recommended to go with the default setup and let all of the features install.


The drop down menu for changing install options in action.


The remainder of the install is straightforward and when you have finished, it is time to take a good look at VirtualBox.

Startup for the Beta Version

If you are using the new beta version, you will see the following two windows when you start VirtualBox.

Note: The first window will display every time you start the beta version.


Registration is not required to use the software, but this window may pop up every so often when starting the beta version if you do not create an account. Simply click “Cancel” to close the window.


The Main Window

Whether you are using the latest stable release or the beta version, this is where all the fun and virtual goodness starts. For our example, there are two operating systems that have been added and are ready to go. From here you can start one of the installed operating systems, add a new one, or discard a current one.

On the right side of the window, you will be able to see details and stats for each operating system.


The File Menu. This is the menu you will need to access the settings for your virtual operating systems and program preferences.


The Machine Menu…


And the Help Menu…


Virtual Media Manager and Preferences

Here you can see basic information about the allotted space (virtual size) and actual size for each of your virtual hard disks. The small size for the Moon Linux O.S. is due to it being run as a “live CD”. You may also perform basic functions such as creating, adding, removing, or releasing individual virtual hard disks.


Here you can view the actual size of the iso images that are associated with each virtual hard disk.


You can access these settings by going to the File Menu and selecting “Preferences”. Here you can change the home folders for your virtual Hard Disks (vdi files) and Machines (snapshots, logs, and xml data files).


This is where you can change the keyboard key that “releases” you from the virtual operating system windows that you have open (i.e to shut down the virtual operating system or do things in your actual operating system). Notice that you can also disable the keyboard auto capture feature for when your virtual operating system starts up.


Choose how often you want VirtualBox to check for the newest updates.


Run VirtualBox in the language of your choice. The new Beta Version has 27 languages to choose from (very nice!).


Network Settings…


The Virtual Operating System Window

Time to get one of those virtual operating systems up and running! Click on and select the system you want to use and click “Start” (for our example, Moon Linux has been chosen).


Here is what the window will look like while starting the virtual operating system (here Moon Linux is being restored from a saved version).


And there it is! A whole different operating system running on your computer.  Notice that with this particular operating system running as a “live CD” version, the meter shows zero hard drive space available.

To start using your new virtual operating system, click your mouse anywhere in the window area and it captures your mouse.  Unless you have disabled it, your keyboard is already captured by the time the window finishes opening up.

Note: Internet connections work through the existing connection that your host operating system has.


A quick look at the menus that are available on the virtual operating system window…

The Machine Menu. If you need to take a system snapshot of your virtual operating system or shut it down, this is where you will need to do it.


Here you can adjust the settings for flash/USB drives, shared folders, and CD/DVD-ROM drives.


And the Help Menu…


Shutting Down your Virtual Operating System

When you are finished using the virtual operating system you have open, go to the Machine Menu and select “Close”. As you can see, you will have three choices.

If you have made changes with a “live CD” system, you can save those changes for the next time you open it by selecting “Save the machine state” (very lovely feature!).

If you do not care about saving any of the changes that you may have made, simply select “Power off the machine”. The next time you start that particular virtual operating system it will start back at a “fresh install” level of operation.



Here is a screenshot showing the Windows 7 Release Candidate and Moon Linux 2.0 running at the same time inside of Windows Vista. It can be so much fun to work with such a variety of systems at the same time!

Note: Depending on the particular operating system you are using, maximum window size will vary. Here the Moon Linux system will only go as large as 800 x 600 pixels while the Windows 7 system will go much larger.


Whether you are curious about a new version/distribution of Linux or just wanting to try out the latest version of Windows, VirtualBox can provide an easy and convenient way to take a good look without having to install over your current system.

    Nice guide thanks, will try that instead of VM-Ware this evening.

    Just out of interest, where can I get that Linux Distro? Looks funky.

    I have searched fro Linux Moon before you LMGTFY me!!

    One reason on why the Moon OS will not do a larger resolution is probably due to you not installing the Guest Additions (which is probably impossible due to it being a live distro). This will provide you with additional drivers/modules and programs. One such driver is the xorg video driver, which will allow you to use higher resolutions. Also with more recent versions of Virtual Box they are also supporting 3D acceleration depending on the version of your xserver (needs to be 1.6 or higher).

    Another feature of Guest Additions is the shared clipboard. This will allow you to copy stuff from the host and past it into the guest or vice versa. The Guest Additions also provides time sync with the host, so both clocks show the same time.

    Guest Additions for linux can be installed by selecting Devices -> Install Guest Additions. This will add the image as /dev/hdc and depending on the distro may auto-mount it. Once it is mounted go into it and run the linux installer (through the shell). Then reboot and it is done.

    One last great feature to mention with the Guest Additions, is once in the GUI you no longer have to use the Right Ctrl to release the mouse. The mouse will move in and out of the window just like any other window on your desktop.

    This software is awesome! Getting better and better each release :)

    Virtual Box is an awesome software. Good competitor to the VMWare Workstation.
    I use this to test them out before installing them to a hard drive. Although sometimes you won’t get the exact same speed when you’re running in on a real install than when you run it in a virtual machine.

    @Alex – Here is the link for the Moon OS homepage. ^__^

    Brilliant, thank you.

    Will try them both tonight.

    Great guide, personally I already knew how to do this but nonetheless an interesting article.



    feature an article on seamless virtualization with VirtualBox.

  9. calebstein

    Just wondering, what desktop environment does moon linux use by default?

  10. Asian Angel

    @calebstein – moonOS uses the Enlightenment Window Manager and can be used alone or in conjunction with GNOME or KDE. There is also an LXDE edition available too. ^__^
