Dual Booting Windows and Ubuntu
A Helpful List of Resources
Why Dual Boot
Dual booting simply means installing two operating systems on one hard drive.
In your career as a computational scientist, you will quickly outgrow the limited capabilities of Windows command prompt. Why Linux is better for programming:
- Compiling code like C++ or FORTRAN is difficult in Windows.
- The Linux terminal is much more powerful than the Windows command prompt
- Native support for SSH and bash
- Linux is “light-weight” and therefore faster than Windows.
Why Not Dual Boot
If your preferred device is UNIX-based, like an apple macbook, there is often no need to dual boot, since everything that can be done on a Linux machine is usually also possible on a mac. Such an approach has the benefit of also supporting the Microsoft Office Suite (which works on a mac too).
If you don’t think you’ll ever need the Microsoft Office Suite, or the small number of other commercial software applications which are a challenge to install on a Linux machine, you can certainly abandon Windows entirely and install Linux alone.
How to Dual Boot
You will need:
- An empty flash drive with at least 5 GB of storage
- At least 25 GB of available hard drive space on the computer you wish to dual boot (recommended: 50 GB)
- Some patience
Once you have those things, you will be able to dual boot. This dual booting video tutorial is very clear and will walk you through each step.
A key step is downloading a recent version of the Ubuntu Linux distribution. You can find that download page here.
After You’ve Installed Linux
When you boot up Linux for the first time you will have very few applications available. A graduate student, Sam Dotson, wrote a bash script that quickly installs some essential applications, as well as some helpful productivity tools. The script is available on GitHub, here. All you need to do in order to execute this script is the following
wget https://raw.githubusercontent.com/samgdotson/ubuntu-post-installer/master/ubuntu-post-installer.sh bash ubuntu-post-installer.sh
Alternatives to Dual Booting
Windows Linux Subsystem
If you don’t want to dual boot and just want to use the Linux terminal, Windows offers an application called “Windows Linux Subsystem.” It works, but you will probably be frustrated because the Linux subsystem doesn’t interface well with the Windows graphical user interface.
For example, it is challenging and beyond the scope of this tutorial to open a graphical user interface from within the Windows Linux subsystem. However, if that is the path you would like to take you can follow this tutorial.
A somewhat more robust approach is to create a virtual machine using VirtualBox. To do this, you’ll need to:
- Boot up Windows (or any other OS)
- Download Ubuntu
- Download and install VirtualBox
- Open VirtualBox
- Following the instructions on the VirtualBox site to create a linux virtual machine using the Ubuntu image file you downloaded in step 2.
- Now you have a fully functional Ubuntu operating system that you can open as an application while booted into your Windows operating system.
Obstacles and Challenges
Caution: New Windows computers with Intel 9th Generation (or higher) CPUs use “Rapid Storage Technology” which must be disabled before installing your chosen Linux distribution. This process is non-trivial and users are warned that there is a risk of data loss. Consider using alternatives to dual booting. If you are determined to dual boot, there is a video tutorial that walks you through the steps.
