But before jumping to the steps of dual booting, let’s have a brief glimpse of what is dual booting? What are the pros and cons of doing it? What are the requirements? Then we will be good to see how to dual boot Windows 10 and Linux.

What is Dual Booting?

In simple words, dual-booting refers to running two operating systems on a single machine at the same time. It’s about installing two operating systems on a machine and selecting which one to use during boot time.

If you are using a dual boot system, a menu is displayed by the boot manager program loaded in your system during booting, allowing you to choose which operating system you wish to continue with.

In case if you don’t know booting refers to the process of switching on the system and loading the operating system.

Well in dual boot, you can have a combination of any operating systems installed on your machine. It can be a combination of different versions of Windows, Windows and Linux, Linux and Mac or Windows and Mac. Sounds great, right!

How many Operating Systems in a Single Machine?

Technically, the term ‘dual boot’ refers to installing just two operating systems on your machine. But that’s not the case!

There is no fixed limit on the number of operating systems that can be installed on your system. It just depends upon the RAM, secondary storage, graphics memory and processor speed of your machine.

Well, a number of operating systems installed on your machine also depends upon the hard disk of your system, whether your hard disk is formatted/Supported MBR or formatted/ Supported GPT.

You can also install a secondary hard drive on your machine and install an Operating System in it and select which hard drive to boot at the time of booting. Or, you can even boot an OS from an external drive.

And in case, if you have only a single hard drive, you can install multiple hard drives in it just by partitioning. So there is no hard and fast rule for the number of operating systems you can have installed in your machine.

Is it safe to Dual Boot?

Before moving to how to dual boot Windows 10 and Linux, let’s see why should you dual boot your system. And what are the harms it might cause to your system if any?

Firstly, let’s see what are the pros if you dual boot your system by discussing a few points.

  • You can switch between the operating systems installed on your machine as per your requirement.
  • In case, if anyone of your operating systems stops working, then you can always boot into the other one.
  • It prevents you from increased overhead and reduced performance of using a virtual machine, in case you need to use multiple OS.
  • It gives you the advantage of using completely dedicated resources to yours currently running OS as compared to VMs where the resources get divided between the OS.
  • It is much faster than virtual machines.
  • You can easily test cross-platform applications without using virtual machines.

But, the dual boot also has some limitations associated with it. Let’s see how it affects your system. We will also discuss the criticality of this process to see if it causes any severe harm to your same.

  • The major problem with the dual boot is of space. Installing multiple operating systems decreases your storage space to a large extent.
  • In order to choose which operating system is to be currently used, a Boot Loader is required which increases the boot time of your machine.
  • You can run only one operating system at a time. For switching to the other one, you always need to reboot your machine.
  • If not installed properly or any mistake in configuration can lead to overwriting of your current operating system.

Dual Boot is totally safe for your system if you are careful with the installations and follow the instructions properly. Setting up a dual boot is not a tough process if proper guidelines are followed.

Pre-requisites to dual boot Windows and Linux

Before starting to dual boot windows 10 and other operating system, you need to fulfill a few pre-requisites for completing the process efficiently. Make sure you are done with each of them before starting the actual process.

  • Sufficient hard disk space

Although space above 50 GB can do the job efficiently, yet it’s recommended to have free space around 100 GB or above. This space will be dedicated to the Linux OS and once installed, cannot be used by Windows again.

  • Flash drive with 8 GB space

You will need a flash drive with a minimum of 8 GB space to serve as a boot drive. Remember creating bootable media will delete all files on your flash drive.

  • Windows 10 license

Make sure you have genuine Windows installed. If you are using a retail version, be ready with the product key. You might need it.

  • UEFI or Legacy BIOS mode

Though not mandatory for all machines but make sure you have Windows 10 installed in UEFI or Legacy mode

  1. Go to ‘Run’. Enter ‘diskmgmt.msc’ and click ‘Run’
  2. Right Click on Window 10 ‘Start’ menu and open ‘Disk Management’.
  • Right Click on the drive you want to partition and click on ‘Shrink Volume’.dual boot windows 10 shrink volume
  • In ‘Enter the amount to shrink’, enter the space in MB required for Ubuntu. You will need 64 GB to 100 GB space for proper installation. Click on ‘Shrink Volume’.

  • Booting Linux from External Drive 

Restart your PC and open ‘Boot Menu’ or ‘UEFI Firmware’ settings during booting of the system. Under ‘Boot Options Menu’, boot Ubuntu from the external drive.


  • Installing Ubuntu

After booting, a desktop will appear on your screen. Now we need to install Ubuntu on our machine.

  • Double Click on the ‘Install Ubuntu’ icon on the desktop.
  • Select your preferred language and keyboard layout.
  • Under ‘Installation type’, select ‘Something else’.
  • In the next screen, select the partition you unallocated while freeing up the disk space and further do as prompted.


  • Restart your machine

After successful installation, restart your machine. Next time you start your machine, Boot Manager will ask you to choose the operating system in which you want to boot into.

So, now you know how to dual boot Windows 10 and Linux OS.
