Creating a Virtual Machine

1. 
   1
   Gather your installation disc(s) or files. When creating a virtual machine, you will need to install the operating system just like you would on a regular computer. This means that you will need the installation disc(s) for the operating system you want to install on the virtual machine.

   • You can also install an operating system by using its ISO file.
2. 
   2
   Click New. This will open the wizard that will guide you through the process to create your first virtual machine.
3. 
   3
   Identify the operating system. On the first screen of the wizard, you will be asked to give the new virtual machine a name as well as choose what operating system you will be installing. Choose the type of operating system from the "Type" menu, and then choose which version you are installing from the "Version" menu.

   • For example, if you are installing Windows 7, choose "Microsoft Windows" from the Type menu, and then "Windows 7" from the Version menu.
   • If you are installing the 64-bit version of the operating system, make sure to choose the 64-bit version from the Version menu.
4. 
   4
   Click Next. It's at the bottom of the window.
5. 
   5
   Set the amount of RAM. You will need to designate how much of your computer's RAM will be allocated to your virtual machine. VirtualBox will automatically choose the recommended minimum amount for the operating system you selected, but you can increase or decrease this if you'd like.

   • You can only go as high as the amount of RAM physically installed in your system.
   • It is not recommended that you set it to the max amount, as there won't be any left for your regular operating system to use when the virtual machine is running.
6. 
   6
   Click Next.
7. 
   7
   Create a virtual hard drive. Select a virtual hard drive option and click Create, then click through the prompts and click Create again. Your virtual machine will need a virtual hard drive in order to install the operating system and any programs.

   • Make sure that the virtual hard drive has at least enough space to install the operating system. Check the specifications for your operating system to see how much space you should allocate at minimum.
   • Remember that any programs you install will also take up space on your virtual hard drive, so plan accordingly.
   • The most common format for virtual hard drives is VDI (VirtualBox Disk Image).
8. 
   8
   Start the operating system installation. Once the virtual machine has been configured, the wizard will close and you will be taken back to the VirtualBox main window. Double-click your new machine in the left menu, then do one of the following:

   • If you are installing from a disc, insert it into your computer, click the "Host drive" drop-down box and click the correct drive letter from the drop-down menu.
   • If you are installing from an image file, click the folder-shaped icon to browse through your computer for the installation image file.
9. 
   9
   Click Start. It's at the bottom of the window. This will prompt VirtualBox to begin reading your disk or file.
10. 
    10
    Install the operating system. After selecting the installation media, the operating system installation will begin. Installation proceeds the same way it would as if you were installing the operating system on a regular computer. See the following guides for instructions on installing the operating system of your choice:

    • Windows 8
    • Windows 7
    • Windows Vista
    • Windows XP
    • Install OS X
    • Linux Mint
    • Ubuntu Linux
11. 
    11
    Boot up your virtual machine. Once the operating system is installed, your virtual machine is ready to go. Simply double-click the name of your virtual machine in the left menu of the VirtualBox main page to start it up. The virtual computer will boot and load into the operating system that you installed.

    • Your virtual machine will run in a window. Whenever the virtual machine window has focus, any keystrokes or mouse clicks will affect the virtual machine and not your physical computer.
12. 
    12
    Shut down your virtual machine. You have a couple of different options when closing your virtual machine, and each will affect the machine slightly differently. When you click the "X" in the upper-right corner of the window, you will be presented with several options:

    • Save the machine state - This will save the virtual machine in exactly the state that it's in when you close it. Any programs you are running will be saved in their current state, and everything will be restored when you start the machine again.
    • Send the shutdown signal - This will send a power-down signal to the virtual machine, and it will shut down as if the power button was pressed on a physical computer.
    • Power off the machine - This will power down the machine as if power was cut to the computer. Nothing will be saved.
13. 
    13
    Take snapshots of your virtual machine. VirtualBox allows you to copy your virtual machine's exact state, allowing you to return to that state at any time. This is incredibly useful for testing software or other configurations.^[2]

    • You can take a snapshot by clicking the Machine menu and selecting Take snapshot. The snapshot will be added to the list of your virtual machines on the left side of the VirtualBox menu.
    • You can restore a snapshot by right-clicking the snapshot and selecting Restore. Any changes to your virtual hard drive since the time the snapshot was created will be lost when the snapshot is restored.

• Question

  How much RAM can be used with a VirtualBox?

  

  Community Answer

  As much as your PC has. For example, if your real PC has 4 GB of RAM, your VM has access to 4 GB of RAM, although that will not leave any RAM for the main PC functions, like the operating system.

• Question

  Does installing VirtualBox make the computer forget the network it's currently connected to?

  

  Banana Head

  Top Answerer

  It does not! Installing VirtualBox will be like installing any other computer program. Your real computer will remain connected to your real WiFi and will not disconnect or forget your network. The same goes for creating a Virtual Machine. Your real computer will never be disconnected from the WiFi.

• Question

  Can I install viruses on the VM without getting a real virus?

  

  Banana Head

  Top Answerer

  Absolutely! One of the incredibly good uses of Virtual Machines is that they are disconnected from the outside world, so you can test new software and illegal software on them without real life repercussions. This includes system-destroying viruses. Based on your settings, the virtual machine might have completely virtual hardware and software. If you destroy the computer so much it can't start, delete the machine and create another one. This arguably the best way to test viruses, since you can create whatever type of computer you want. To summarize, yes. This is a great idea. Nothing from the virtual machine will affect your real life computer if you're careful. Just in case, scan with AV.

• Question

  Can XP Pro 64 be installed on VirtualBox?

  

  Community Answer

  Yes. As long if you're using a 64-bit PC, create a virtual machine and select it as "Windows XP 64-bit" and have the iso file of Windows XP Pro x64, then you can install VirtualBox.

Tips

• VirtualBox can be used to test software that won't work on your computer's built-in operating system. For example, if you have a Mac and you want to test a Windows program, VirtualBox provides a solution.

Warnings

• Any operating system used in VirtualBox will run somewhat sluggishly due to the sheer processing power needed to run two operating systems at once on one computer.
