This content is available in 7 different language

Setting up a dual boot system can be a great way to experience the best of both worlds, Windows and Ubuntu Linux. With a dual boot setup, you can choose which operating system to use each time you start your computer. In this detailed guide, we will walk you through each step of the process of setting up dual boot for Windows and Ubuntu, ensuring a smooth and easy transition. Get ready because this is going to be a comprehensive guide.

Understanding dual boot

Dual booting involves installing two operating systems on the same computer and choosing which one to load during the boot process. One might want to dual boot for a variety of reasons: perhaps some software runs better on one system, or you're exploring different systems for development purposes. Whatever the reason, a dual boot setup is designed to make both operating systems available to you without requiring separate machines.

Preparing your system

Before you begin the dual boot setup, take the following preliminary steps to ensure a smooth installation process:

1. Back up your data

It is very important to create a backup of your important files and data. Dual booting requires partitioning your hard drive, which can sometimes lead to data loss if not done correctly. Use cloud storage, external hard drive, or any other backup service to keep your data safe.

2. Check the system requirements

Make sure your computer is compatible and meets the necessary requirements for both Windows and Ubuntu. Hardware requirements mainly include having enough storage space and RAM.

3. Free up disk space

Make sure you have enough free space on your hard drive. You will need space to install the second operating system and enough space for software and personal files to function optimally. Generally, allocate at least 20 GB to run Ubuntu smoothly.

4. Download Ubuntu

You will need to download the Ubuntu ISO file from the official Ubuntu download page. Choose the version you want to install; Long Term Support (LTS) versions are highly recommended for stability.

5. Create a bootable USB drive

You will need a bootable USB drive to install Ubuntu. You can use software like Rufus (for Windows) or UNetbootin (for Windows, Mac, and Linux) to create this bootable drive with the ISO file you downloaded:

1. Insert your USB flash drive into your computer.
2. Launch Rufus or UNetbootin.
3. Select the USB drive in the “Device” field.
4. Click “Select” and choose the downloaded Ubuntu ISO file.
5. Click "Start" and wait for the tool to finish creating the bootable USB drive.

Partitioning a hard drive

Partitioning is the process of dividing your hard drive into different areas where different file systems can be installed. Windows needs its own file system, while Ubuntu uses another.

Access to disk management

Access Disk Management in Windows to make space for Ubuntu:

1. Press Windows + X and select “Disk Management” from the menu.
2. Right-click on the drive you want to partition, probably your main drive.
3. Select "Decrease Volume."
4. Specify the amount of space to shrink; make sure this size is at least 20GB.

Allocate free space

After shrinking the volume, you will have unallocated space where Ubuntu will be installed. This space will be used during the Ubuntu installation process when you create the necessary partitions.

Installing Ubuntu alongside Windows

Once the preparations are done, you are ready to install Ubuntu alongside Windows. Follow these steps carefully:

1. Boot from a USB drive

Insert the bootable USB drive into your computer and restart. You must boot from the USB drive:

1. As soon as your computer turns on, access the Boot Menu (common keys to press include F2, F10, F12, or ESC).
2. Choose the option to boot from your USB drive.
3. You will see the Ubuntu welcome screen; here you will have the option to “Try Ubuntu” or “Install Ubuntu”.
4. Select “Install Ubuntu”.

2. Installation steps

Follow the installation steps provided by the Ubuntu installer:

  1. Select your preferred language and click “Continue”.
  2. Connect to the Internet, which is recommended for downloading updates and third-party software during installation.
  3. Choose whether to install updates and third-party software during installation. It is often useful to have these installed beforehand.
  4. When you get to the "Installation Type" screen, select "Something else" to manually partition the drive and make sure the installation is directed to the correct partitions.

3. Manual segmentation

Allocate unallocated space for Ubuntu by creating the following partitions:

1. Root partition: Create a partition as ext4 with mount point / Allocate at least 12-15 GB here.
2. Swap Partition: Create a swap partition, which is usually equal to your system's RAM size.
3. Home partition: Optionally, create a /home partition to store personal files separate from system files.

After creating the partition, click “Install Now” and confirm your choice. Continue the installation by following the prompts to choose your time zone and keyboard layout.

4. User account setup

Set up your user account by providing the name, username, password, and computer name. Ubuntu will use these credentials to create your primary user account.

5. Installation progress and completion

Allow the installation to complete, which may take some time. When done, restart your computer when prompted. Don't forget to remove the USB drive to ensure the system boots from the hard drive.

Bootloader setup after installation

Upon restart, you will see the GRUB boot menu. GRUB is the bootloader that enables you to choose between Windows and Ubuntu at startup.

Switching between operating systems

Using the GRUB boot menu, you can easily choose whether to run Windows or Ubuntu every time you start your machine. This flexibility is one of the major advantages of a dual-boot setup.

Troubleshooting tips

If any problems arise during or after installation, here are some troubleshooting suggestions:

Maintaining your dual-boot setup

Once setup, keep both systems updated regularly with the latest software and security updates. Allocate space wisely and ensure good disk management so that each OS runs smoothly.
Use cloud storage or external drives for important data, ensuring easy access from both systems.

Removing Ubuntu and resizing windows (optional)

If you ever decide to remove Ubuntu:

Conclusion

By following this guide, you have successfully set up a dual boot system with Windows and Ubuntu. You now have the flexibility to choose which operating system best suits your needs at any given time. Enjoy the freedom and flexibility of using both Windows and Ubuntu on the same machine!
