Introducing How to Set Up a Windows Virtual Machine in Linux

Here’s a step-by-step guide to doing just that. Need to run Windows software in Linux? One of the typical answers is to install Windows in a virtual machine. If that sounds scary or overwhelming for you, don’t worry.

To get started, you’ll need the following things:

  • Virtual machine software (what is a virtual machine?)
  • Official Windows ISO (bootable disc or USB) with legal Windows license
  • PC or laptop that supports virtualization (you’ll also need an external DVD drive if your laptop is an ultrabook, or you can build your own)
  • Sufficient system RAM

Now, the first two things are pretty easy for you to get. It’s rare to own a PC without a Windows license, even when you’re running Linux, but you’ll need one that has a virtualization feature.

Virtualization, if not enabled by default, can be switched on in the system BIOS. The path to doing this will depend on the hardware you’re using. For the best results, boot into your system BIOS and look for references to Intel VT (on an Intel architecture PC) or AMD-V (on a PC with AMD CPU and motherboard).

This video explains what you should be looking for:

With regards to system RAM, while you might get away with some virtualization on old operating systems with 4 GB, you should be starting with 8 GB for the best results. The laptop used for this tutorial has 12 GB RAM.

Choosing Virtualization Software

Before installing Windows, you need to decide on your preferred virtualization application. Three are available for Linux:

  1. Oracle VirtualBox (Free) — Probably the most popular choice, and free, released as open source software under the GNU General Public License, version 2.
  2. VMWare Player (Free or $250) — The free version of the popular corporate virtualization tool VMWare Workstation. VMWare Player is free for domestic users.
  3. QEMU (Free) — Short for Quick Emulator, QEMU is capable of running a wide selection of operating systems, including many fringe and forgotten platforms.

While QEMU is arguably the superior option for Linux systems, we want a solution that can run Windows with a minimum of fuss and can be installed quickly. You’re free to choose any of the above, of course, but for this tutorial we’ll be using Oracle VirtualBox.

Install VirtualBox from the Software Center in Ubuntu or from the corresponding application on your Linux distro. You can also use the command line. For Debian-based systems:

sudo apt-get install virtualbox 

Then install the VirtualBox guest utilities:

sudo apt-get install virtualbox-guest-dkms 

This will help you with moving data between the host system (your Linux PC) and the guest system (your virtual Windows environment).

Set Up Windows in Oracle VirtualBox

With VirtualBox installed on your Linux PC, launch the software.

Because we want a usable version of Windows, we’ll be selecting the options for Windows 7, but you should choose the settings that match the version you’re installing.

Start by clicking New, then give the virtual device a name. In the Type drop-down menu ensure that Windows is selected, and in Version, the correct Windows version. You can run pretty much anything from Windows 3.1 to date.

Click Next to continue, and in the subsequent screen, select the Memory size for the virtual machine. A default recommended size will be suggested based on the OS you chose and the hardware of your physical computer.

Click Next to create your virtual hard disk drive, again choosing the default option unless you have a particularly large amount of data to run in the VM.

Once done, hit Create, then select your prefered file type. If you’re just going to use the virtual hard disk with VirtualBox, hit Next, otherwise choose a different format as appropriate. You must then specify whether the virtual HDD should be dynamically allocated (i.e. it increases in size as required, to the pre-selected upper limit) or a fixed size. In most cases, you’ll want dynamic.

Click Next to continue, confirm (or change) the file name, location and size, then Create again to continue.

Installing Windows on Linux

With the virtual machine configured — think of it as building a PC but with virtual components — you’re now ready to install Windows. Whether you’re using a disc or a USB stick to deliver the ISO, now is the time to insert the media holding the ISO file.

Now, click the green Start arrow, and select the location of the source data — the Windows installer disc. Click Start, then wait as the virtual computer loads the Windows setup.

If you’ve installed Windows before, you should be familiar with this — if not, the wizard will help you through the process.

Launch Windows and Install Software!

If you’ve made it this far, you’re done. You should be able to boot into Windows and install software, either via DVD (thanks to the VirtualBox tools) or by downloading and installing.

All of your usual Windows applications should run as normal, restricted only by the hardware of your host computer — the physical PC onto which you installed VirtualBox. Using a virtual machine is probably the best way to get Windows apps and games running if things like Wine and PlayOnLinux fail you.

Having a Windows VM that you can easily switch on and off at your convenience, while continuing with your daily Linux computing, is a massive advantage. If you need to run Windows software and have the hardware to support virtualization, then this is a great solution.
