Modern IT specialists and enthusiasts are often faced with the need to test programs in an isolated environment or run operating systems other than the main one. It is ideal for these purposes Oracle VirtualBox is a powerful open source virtualization tool. This technology allows you to run multiple operating systems on one physical computer without the risk of damaging the main system.
The program installation process seems simple, but contains many nuances, which, if ignored, can lead to unstable operation of guest systems. In this material we will analyze in detail, how to install Oracle VirtualBox onto a Windows computer and look at the key steps for initial setup. Proper preparation will ensure maximum performance from your virtual labs.
Virtualization has become the de facto standard for developers, testers, and information security specialists. Understanding of operating principles hypervisor the second type, which is this product, will open up new opportunities for you in working with software. Let's take a closer look at the installation procedure.
Preparing the system and downloading the distribution
Before you begin installation, you must ensure that your computer meets the minimum system requirements. For correct operation Oracle VirtualBox Requires a 64-bit processor with hardware virtualization support. Typically this function is denoted as Intel VT-x or AMD-V in the BIOS/UEFI of the motherboard.
It is also important to free up enough disk space, as operating system images can take up a significant amount of memory. It is recommended to have at least 20-30 GB of free space for comfortable work with one virtual machine. Also, make sure you have the latest Windows update installed on your PC, as older versions may conflict with the program's network drivers.
The installation file should be downloaded exclusively from the developer’s official website to avoid the introduction of malicious code. Go to oracle.com, find the downloads section and select the version for Windows hosts. The file weighs about 100-120 MB and contains all the necessary components for basic work.
⚠️ Attention: If an error appears when you run the installer about the hypervisor being unavailable, you need to go into the BIOS and activate virtualization technologies (VT-x/AMD-V), and also disable the conflicting Hyper-V functions in Windows components.
Before downloading, check the bitness of your main system (32 or 64 bits), although only the 64-bit version is relevant for modern computers.
Software Installation Process
After downloading the executable file, run it as an administrator to avoid problems with access rights to system folders. The installation wizard will offer a standard file path, which is best left unchanged unless you have specific requirements for the disk structure. On the first welcome screen, simply click "Next" to continue.
At the component selection stage, it is recommended to leave all options active, especially Oracle VM VirtualBox USB Support and network bridges. These modules are critical for forwarding USB devices inside the virtual machine and organizing network interaction. Disabling these options may limit the functionality of systems you create in the future.
During the process of copying files, the system may ask for confirmation to install network interfaces - be sure to agree with this action. Without virtual network adapters, your guest OS will not be able to access the Internet or local network. The installation may take a few minutes depending on the speed of your hard drive.
☑️ Ready to install
Once the files are copied, the wizard will prompt you to launch the application immediately after closing the window. Make sure the checkbox is checked and click Finish. After this, a shortcut will appear on the desktop, and an indicator of the activity of network interfaces may temporarily appear in the system tray.
Creating your first virtual machine
Launching Oracle VM VirtualBox, you will see the main manager window, which is empty for now. To create a new system, click the "Create" button in the top menu bar or use hotkeys. A wizard window will open where you will need to enter the name of the machine to be created and select the type of operating system from the drop-down list.
It is important to correctly specify the OS version, since the hardware emulation settings depend on this. For example, when choosing Windows 10 (64-bit) the program will automatically suggest the optimal amount of RAM and type of hard drive controller. Do not ignore this step, as incorrect selection may result in the installation image being unable to boot.
The next step is to decide how the storage of the virtual hard disk data will be organized. You can create a new virtual disk or use an existing one. For beginners, it is recommended to select the option to create a new disk format VDI (VirtualBox Disk Image) since it is native to this platform.
| Parameter | Recommended value | Description |
|---|---|---|
| Disk type | VDI | VirtualBox native format |
| Storage format | Dynamic | The file grows as it fills |
| Disk size | 25-50 GB | Depends on the installed OS |
| RAM | 4096 MB | Half of the PC's physical memory |
Setting up hardware settings
After creating an object in the list on the left, you need to configure its hardware before the first launch. Select the machine and click the "Configure" button. In the "System" section you can change the boot order and the amount of allocated RAM. You should not give the virtual machine more than 50% of the total RAM of your computer so that the main system does not start to slow down.
The "Processor" tab allows you to increase the number of virtual cores allocated to the guest OS. For modern tasks, it is recommended to allocate at least 2 cores, which will significantly speed up the interface and code compilation. However, remember that hardware virtualization has its overhead, and over-provisioning can destabilize the host machine.
Pay special attention to the “Display” section, where you need to increase the amount of video memory to the maximum value (usually 128 MB). Also be sure to check the box next to “Enable 3D acceleration”, which will allow the guest system GUI to run smoothly. Without this setting, windows may open with a delay and videos may play jerkily.
⚠️ Attention: Changing processor and memory settings is only possible when the virtual machine is turned off. If the machine is running or in the Saved state, menu items will not be available.
Operating system installation
Now that the virtual hardware is configured, you need to install the operating system itself. To do this, you will need the installation ISO image of the desired OS. In the main program window, click the "Run" button, and upon first launch the system will ask you to specify the path to the boot disk.
Select the image file on your hard drive and the virtual machine will begin the boot process as if you had inserted the DVD into a real computer. Next, the process completely repeats the usual installation of Windows or Linux: partitioning the disk, copying files and initial setup. All actions take place in a separate window, isolated from your main system.
During installation, the guest OS will use basic video drivers, so the screen resolution will likely be low. Don’t worry, after installing the system and specialized add-ons, the resolution will change automatically, and the mouse cursor will become common for both windows. This stage requires time comparable to the usual installation of the OS on a physical PC.
What should I do if the installation freezes?
Often freezes occur due to processor instruction conflicts. Try turning on or off the PAE/NX option in the machine settings (System -> Processor), and also check whether virtualization is activated in the BIOS.
Installing guest OS additions
After successfully loading the desktop of the new system, you need to install Guest Additions (Guest OS Additions). This package of drivers and utilities greatly improves integration between host and guest, providing shared buffering, USB forwarding, and automatic screen resolution changes. Without this package, working with a virtual machine will be extremely inconvenient.
To install, select “Devices” -> “Mount disk image of Guest OS Add-ons” from the virtual machine window menu. A virtual CD drive containing the installer will open inside the guest system. Launch it and follow the wizard's instructions, agreeing to install video and input drivers.
After completing the installation of add-ons, be sure to reboot the virtual machine. You will notice that the system boots at the correct screen resolution that supports full screen mode. The function of dragging files (Drag'n'Drop) between windows will also become available if it has been activated in the settings.
⚠️ Attention: In Linux guest systems, for add-ons to work correctly, it is often necessary to install the compiler and kernel header files (build-essential and linux-headers packages) before running the add-on installer.
Installing Guest Additions is a mandatory step for comfortable work, as it ensures forwarding of the clipboard, folders and the correct screen resolution.
Frequently asked questions (FAQ)
Is it possible to run Oracle VirtualBox without virtualization enabled in the BIOS?
No, for 64-bit guest systems to work and for stable operation of the hypervisor itself, VT-x/AMD-V support must be activated at the motherboard level. Without this, the program will either not start the machine or will work extremely slowly through software emulation.
How to transfer a file from the main system to the virtual one?
The easiest way after installing add-ons is to use the shared folder (Shared Folders) in the machine settings or simply drag the file with the mouse if Drag'n'Drop is enabled. You can also use a network environment or a USB flash drive inserted inside.
Why is the virtual machine slow?
The main reasons: not enough RAM is allocated, 3D acceleration is not installed, Guest OS Add-ons are not installed, or the host system is overloaded with other tasks. Also, the speed depends on the type of disk (SSD is much faster than HDD).
Is it safe to run viruses in VirtualBox?
The virtual machine is isolated, but not completely. If the network is configured correctly (NAT mode) and there are no shared folders, the risk is minimal. However, there are techniques to "obga" from a virtual environment, so you should run dangerous samples with caution and with the network turned off.
