Step-by-Step Tutorial
Step 1: Download Ubuntu ISO
1. **Visit the Official Ubuntu Website**
Open your preferred web browser and navigate to the official Ubuntu website at ubuntu.com/download. This is the primary source for downloading the latest versions of Ubuntu.
2. **Navigate to the Download Section**
Once on the homepage, look for the “Download” section. This is usually prominently displayed. Click on it to proceed to the various available versions of Ubuntu.
3. **Choose Your Version**
You will see several versions of Ubuntu, including the latest LTS (Long Term Support) version and other variants. Select the version that best suits your needs. For most users, the latest LTS version is recommended due to its stability and support.
4. **Click on the Download Link**
After selecting your desired version, click on the download link. The download should start automatically. If prompted, choose a location on your computer where you would like to save the ISO file.
5. **Monitor the Download Progress**
Keep an eye on the download progress to ensure it completes successfully. Using a reliable internet connection is crucial to avoid interruptions during this process.
6. **Verify the Download**
After the download is complete, it is advisable to check the SHA256 checksum to verify the integrity of the downloaded file. This ensures that the file has not been corrupted or tampered with. You can do this by running the following command in your terminal:
sha256sum /path/to/your/ubuntu.isoCompare the output with the checksum provided on the Ubuntu website.
7. **Check Disk Space**
Before proceeding to the next step, ensure that you have sufficient disk space available on your computer to accommodate the ISO file and any subsequent installations.
Step 2: Create a Bootable USB Drive
1. **Download the Required Software**: First, you need to download a tool to create a bootable USB drive. If you are using Windows, download Rufus from its official website. For macOS or Linux users, download Etcher.
2. **Insert the USB Drive**: Plug in your USB drive into your computer. Ensure that it has at least 4GB of free space, as this is the minimum required to hold the Ubuntu installation files.
3. **Format the USB Drive**: Before creating the bootable drive, it is advisable to format the USB drive to FAT32. This can be done by right-clicking on the USB drive in your file explorer and selecting the ‘Format’ option. Choose FAT32 as the file system and proceed with the formatting. Remember, this will erase all data on the USB drive.
4. **Open the Bootable Drive Creation Tool**: Launch Rufus or Etcher, depending on your operating system.
5. **Select the USB Drive**: In the tool, select your USB drive from the device list. Be very careful to choose the correct drive, as all data on it will be erased.
6. **Choose the Ubuntu ISO File**: Click on the option to select an ISO file and navigate to the location where you downloaded the Ubuntu ISO. Select it.
7. **Start the Creation Process**: Click on the ‘Start’ button in Rufus or ‘Flash!’ in Etcher. Confirm any prompts that appear. The tool will now create a bootable USB drive with the Ubuntu installation files.
8. **Completion**: Once the process is complete, safely eject the USB drive. Your bootable USB drive is now ready for use in installing Ubuntu.
Step 3: Boot from USB Drive
1. **Insert the Bootable USB Drive**: Begin by inserting the USB drive that contains the Ubuntu installation files into a USB port on your computer. Ensure that the USB drive is properly connected and recognized by the system.
2. **Restart Your Computer**: Once the USB drive is in place, restart your computer. You can do this by selecting the restart option from your operating system’s menu or by pressing the power button.
3. **Enter BIOS/UEFI Settings**: As your computer starts up, you will need to enter the BIOS or UEFI settings. This is typically done by pressing a specific key during the boot process. Common keys include F2, F10, Delete, or Esc. Refer to your computer’s manual for the exact key to press.
4. **Change Boot Order**: Once in the BIOS/UEFI menu, navigate to the boot options. Look for a section labeled “Boot Order” or “Boot Options.” Here, you will need to set the USB drive as the primary boot device. Use the appropriate keys (often +/- or ↑/↓) to move the USB drive to the top of the list.
5. **Disable Secure Boot (if necessary)**: If your computer has Secure Boot enabled, you may need to disable it to allow booting from the USB drive. This option is usually found in the “Security” or “Boot” tab.
6. **Save Changes and Exit**: After making the necessary changes, be sure to save them. Look for an option that says “Save and Exit” or simply press the key indicated for saving changes (often F10). Confirm any prompts that appear.
If done correctly, your computer should now boot from the USB drive, and the Ubuntu installation menu will appear, allowing you to proceed with the installation process.
Step 4: Start Ubuntu Installation

2. **Select Installation Option**: You will be presented with two options: ‘Try Ubuntu’ and ‘Install Ubuntu’. If you want to explore the live environment to check hardware compatibility, select ‘Try Ubuntu’. This allows you to use Ubuntu without making any changes to your system. If you are ready to install, select ‘Install Ubuntu’.
3. **Connect to the Internet**: If you chose ‘Install Ubuntu’, the installation wizard will prompt you to connect to the internet. It is recommended to connect to Wi-Fi or Ethernet to download updates during the installation. Make sure to have your Wi-Fi password ready if you are connecting wirelessly.
4. **Choose Installation Type**: After connecting to the internet, the installation wizard will ask you how you want to install Ubuntu. You can choose to erase the disk and install Ubuntu, install alongside another operating system, or use advanced partitioning options. Select the option that best suits your needs.
5. **Follow the Installation Wizard**: The installation wizard will guide you through the remaining steps, including selecting your timezone, keyboard layout, and creating a user account. Follow the prompts carefully to complete the installation process.
6. **Complete Installation**: Once the installation is finished, you will be prompted to restart your computer. Remove the installation media when instructed, and your system will boot into the newly installed Ubuntu operating system.
Step 5: Select Installation Type

– **Install Ubuntu Alongside Another Operating System**: If you have another operating system installed (like Windows), this option allows you to keep it while also installing Ubuntu. This is a great choice if you want to dual-boot and have the ability to choose between operating systems at startup.
– **Something Else**: This option gives you full control over the partitioning of your disk. You can create, delete, or resize partitions as needed. This is recommended for advanced users who are familiar with disk management.
