If you are already using MacOS, Ubuntu, or an official flavor of Ubuntu, you can skip this section. Otherwise, click on the small arrow to the left of the method you would like to use below to expand that section, and then follow the installation instructions.
Please Note: We can only support the operating systems indicated above. Our instructions have been tested with MacOS, Ubuntu, and official flavors of Ubuntu. We do not recommend installing an OS that is only based on Ubuntu (like Mint, Pop!_OS, ElementaryOS, etc).
This curriculum only supports using a laptop, desktop or supported Chromebook. We cannot help you set up a developer environment on a RaspberryPi or any other device.
Installing a Virtual Machine (VM) is the easiest and most reliable way to get started creating an environment for web development. A VM is an entire computer emulation that runs inside your current Operating System (OS), like Windows. The main drawback of a VM is that it can be slow because you’re essentially running two computers at the same time. We’ll do a few things to improve its performance.
Installing a VM is a simple process. This guide uses Oracle’s VirtualBox program to create and run the VM. This program is open-source, free, and simple. What more can you ask for? Now, let’s make sure we have everything downloaded and ready for installation.
Once you have completed these instructions, you are expected to work entirely in the VM. Maximize the window, add more virtual monitors if you have them, fire up the Internet Browser in the Whisker Menu on the top left of the desktop. You should not be using anything outside of the VM while working on The Odin Project. If you feel like you have a good understanding after using the VM for a while, and or want to improve your experience, we recommend dual-booting Ubuntu, which there are instructions for below.
Click here and download VirtualBox for Windows hosts.
There are thousands of distributions of Linux out there, but Ubuntu is undoubtedly one of the most popular and user friendly. When installing Linux on a VM, we recommend downloading Xubuntu 20.04. Xubuntu uses the same base software as Ubuntu but has a desktop environment that requires fewer computer resources and is therefore ideal for virtual machines.
Installing VirtualBox is very straightforward. It doesn’t require much technical knowledge and is the same process as installing any other program on your Windows computer. Double clicking the downloaded VirtualBox file will start the installation process. During the installation, you’ll be presented with various options. Leave them in their default state unless you are certain about their behavior. As the software installs, the progress bar might appear to be stuck; just wait for it to finish.
Now that you have VirtualBox installed, launch the program. Once open, you should see the start screen.
Click on the “New” button to create a virtual operating system. Give it a name of “Xubuntu”, leave the “Machine Folder” as is, set the “Type” to “Linux” and be sure “Version” is set to “Ubuntu (64-bit)”. Continue by pressing “Next”, and choose the following options in the next steps:
Memory size: Use 2048 MB or more if possible. Ideally, this amount should be about half of your computer’s maximum memory. For example, if you have 8 GB of RAM, allocate 4096 MB (1024 MB to 1 GB) to your VM’s operating system. If you do not know how much RAM is available to you, please click here.
Hard disk: Click “Create a virtual hard disk now”.
Hard disk file type: Choose the VDI (VirtualBox disk image) option.
Storage on physical hard disk: “Dynamically allocated”.
File location and size: We recommend at least 20 GB for the virtual hard disk.
After completing the last step, click the “Create” button. Your new virtual OS should now appear in the menu. With Xubuntu selected, click on the “Settings” button on the navigation bar, highlighted in red below.
Click on the “System” tab and then the “Processor” tab. Increase the Processor(s) to 2. If this screen prevents you from increasing processors, you likely need to enable virtualization in your computer’s BIOS/UEFI settings. If you have a single core processor, you will not be able to change this setting.
If you have more than one monitor, you can create additional monitors by increasing the “Monitor Count” attribute in the “Display” tab. Please be sure to increase the “Video Memory” slider until it is in the green. All other settings should remain default.
With all that complete, click “OK” to save the changes.
You cannot install Xubuntu without mounting the ISO you downloaded earlier. We will do that now. Click on the section labeled [Optical Drive] Empty to the right of the text labeled IDE Secondary Master under Storage at the main VirtualBox screen, while Xubuntu is selected. This will open up a dropdown menu, click Choose/Create a disk image….
The next window that opens, click on the Blue Circle with the Green Plus labeled Add, and locate your Xubuntu ISO file you downloaded earlier. Choose the ISO and click open.
You should now see the ISO on the Disk Selector screen. Click it and hit the Choose button at the bottom.
You can now start the VM by right clicking on the icon in the menu and by clicking the large “Start” arrow at the top.
When the VM starts up, you’ll be asked to install Xubuntu. All of the default options can be left alone, including the Installation type (“Erase disk and install Ubuntu”). It may sound dangerous, but the VM can only see the “Hard Drive” of the VM. This is the beauty of VMs: the ability to separate the physical space of your computer across many VMs. While installing, be sure to take note of the password and username you chose, we will need these later.
The rest of the installation is pretty straightforward, but if you have any questions, you can find Ubuntu’s official installation guide for Ubuntu here.
Your regular operating system (Windows in this case) is called the Host, and all other operating systems that run as VMs are called Guests. To make working in your Guest OS easier, you need to install Guest Additions. It adds useful functionality to the Guest OS, such as full-screen guest mode.
While your VM is running, do the following steps:
Software Updaterin the text field that opens up and click on the item with the same name.
ctrl + alt + tor opening the Whisker Menu and typing in Terminal (the shortcut is obviously faster).
sudo apt install linux-headers-$(uname -r) build-essential dkms. (note: You cannot copy and paste between your guest OS and host OS (Windows), so when copying these commands you need to open this page in your VM through your
Web Browserby pressing
Windows + w(the Windows key should be between the left ctrl and alt keys) or opening the Whisker Menu and typing in Web Browser.)
sudo apt-get install build-essentialand enter your password. Otherwise, move on to Step 9.
Ywhen it asks you to and let it finish installing. Close the terminal when it is finished.
VBoxLinuxAdditions.runbefore proceeding to step 13. But if you do not see a File Manager window appear, then navigate to the desktop by minimizing all opened windows, and then double-click on the CD icon on the VM desktop.
sudo ./VBoxLinuxAdditions.runand hit enter.
rebootand hitting enter in a terminal).
Here are some tips to help you get started in a virtual environment:
All your work should happen in the VM. You will install everything you need for coding, including your text editor, Ruby, and Rails inside the VM. The Xubuntu installation inside of your VM also comes with a web browser pre-installed.
To install software on your VM, you will follow the Ubuntu installation instructions from inside the Xubuntu VM.
To take a screenshot (which you might need when asking for help on our Discord), you can either press the Host Key (Right Ctrl) + E or click “View -> Take Screenshot” for a full screenshot, or you can click the “Whisker Menu” and type in “Screenshot”, in which you can choose to take a screenshot of your entire screen, the current window you are on or to select a certain area to capture.
All of the development that you’ll do related to TOP will be done in the VM.
We recommend going full screen (View > Full-screen Mode) and forgetting about your host OS (Windows). For best performance, close all programs inside of your host OS when running your VM.
If you added additional monitors in the “Display” tab of your VM settings, with the VM running, clicking “View” -> “Virtual Screen 2” -> “Enable”. You can run fullscreen with multiple monitors, but it may ask for more “Video Memory”, which you should have increased when adding more monitors. Upon exiting fullscreen, your secondary display may close. You can reopen it with these instructions.

Dual-booting provides two operating systems on your computer that you can switch between with a simple reboot. One OS will not modify the other unless you explicitly tell it to do so. Before you continue, be sure to back up any important data and to have a way to ask for help. If you get lost, scared, or stuck, we’re here to help in the Odin Tech Support chat room. Come say “Hi”!
First, you need to download the version of Ubuntu you want to install on your computer. Ubuntu comes in different versions (“flavors”), but we suggest the standard desktop Ubuntu. If you’re using an older computer, we recommend Xubuntu. Be sure to download the 64-bit version of Ubuntu or Xubuntu.
Next, follow this guide to create a bootable flash drive so that you can install Ubuntu on your hard drive. If you don’t have a flash drive, you can also use a CD or DVD.
Note: You can use this method to try out different flavors of Ubuntu if you’d like. These images allow you to try out different flavors without committing to an installation. Be aware that running the OS from a flash drive will cause the OS to be slow and can decrease the life of your flash drive.
First, you need to boot Ubuntu from your flash drive. The exact steps may vary, but in general, you will need to do the following:
For example, on a Dell computer, you would need to plug in the flash drive, reboot the computer, and press the F12 key while the computer is first booting up to bring up the boot menu. From there, you can select to boot from the flash drive. Your computer may not be exactly the same, but Google can help you figure it out.
If you would like to test out the version of Ubuntu on the flash drive, click ‘Try me’. When you have found a flavor of Ubuntu you like, click ‘Install’ and continue to the next step.
Installing Ubuntu is where the real changes start happening on your computer. The default settings are mostly perfect, but be sure to “Install Ubuntu alongside Windows” and change the allocated disk space allowed for Ubuntu to 30 GB (or more if you can).
For step-by-step instructions, please follow this installation guide from the creators of Ubuntu.
With the recent addition of Linux (Beta), the Chrome OS platform has been opened up to the ability to install native Linux applications. If you wish to use your Chromebook to complete The Odin Project, you will need to ensure you meet a couple requirements:
Once you have successfully met both of these requirements, you should be able to follow along with the Linux instructions throughout the entire curriculum.
Note for CloudReady users
Currently there is a bug preventing CloudReady v83.4 from successfully installing Linux (Beta). This was resolved in version 85.2.
