Prerequisites Before Installing

Before diving into the installation process, there are a few things you’ll need to prepare:

• System Requirements: At least 4GB RAM, 25GB of free disk space, and a multi-core CPU is recommended.
• Ubuntu 26.04 ISO File: Download the official ISO image from the Ubuntu website.

Downloading and Installing VirtualBox or VMware

You need virtualization software to run Ubuntu without installing it on your main system:

1. Installing VirtualBox

• Visit the official VirtualBox website.
• Download the installer for your operating system (Windows, macOS, or Linux).
• Run the installer and follow the on-screen instructions.

2. Installing VMware Workstation Player

• Download from the VMware official site.
• Install the application like any regular software.
• Choose ‘Use for free for non-commercial use’ during setup if applicable.

Setting Up Ubuntu 26.04 on VirtualBox

Once VirtualBox is installed, follow these steps to create your virtual machine:

1. Open VirtualBox and click “New”.
2. Enter the name (e.g., “Ubuntu 26.04”), choose “Linux” as the type, and “Ubuntu (64-bit)” as the version.
3. Allocate memory (minimum 2048 MB; 4096 MB is recommended).
4. Select “Create a virtual hard disk now”.
5. Choose VDI (VirtualBox Disk Image), set storage to dynamically allocated, and assign at least 25GB for disk space.
6. With your new VM selected, click “Settings” > “Storage”, then under “Controller: IDE” click the empty disk icon. Browse and select the Ubuntu 26.04 ISO.
7. Click “Start” to boot into the Ubuntu installer.

Installing Ubuntu 26.04 LTS on VirtualBox

Now that you’ve initiated the VM with the Ubuntu ISO, follow the installation steps:

1. Select your language and click “Install Ubuntu”.
2. Choose your keyboard layout.
3. Select “Normal installation” and check the boxes for downloading updates and third-party software.
4. Choose “Erase disk and install Ubuntu” (don’t worry—this only affects the virtual disk).
5. Confirm changes and click “Continue”.
6. Set your time zone and create your user account with login details.
7. Wait for the installation to complete, then restart the VM when prompted.

Installing in VMware Workstation Player

The process in VMware is slightly different but just as straightforward:

1. Open VMware and click “Create a New Virtual Machine”.
2. Select “Installer disc image file (ISO)” and browse for the Ubuntu ISO you downloaded.
3. Name the VM and select disk location.
4. Allocate at least 25GB disk space (Split into multiple files for easier management).
5. Go to “Customize Hardware” to set memory and processors. 4GB of RAM and 2 CPUs are recommended.
6. Click “Finish” and then “Power on this virtual machine” to start the installer.

From here, follow the same installation process as described for VirtualBox. The graphical Ubuntu installer is user-friendly and guides you through formatting, setting up users, and finalizing the OS installation.

Post-Installation Tips

After successful installation, there are a few optional (but recommended) steps to enhance your Ubuntu experience:

• Install Guest Additions (VirtualBox): This enables auto-resizing windows, shared folders, clipboard sync, and better graphics.
• Install VMware Tools (VMware): Offers similar integration features for VMware users.
• Update Ubuntu: Open the terminal and run sudo apt update && sudo apt upgrade.
• Install Essential Software: Such as Git, curl, or GNOME Tweaks via the Software Center or terminal.

Common Troubleshooting

Even the simplest setups can encounter issues. Here are some typical problems and fixes:

• Black Screen on Boot: Try enabling/disabling 3D acceleration in settings.
• Mouse Integration Not Working: Ensure Guest Additions/VMware Tools are installed.
• No Internet Connection: Check VM’s network adapter settings—set it to Bridged or NAT mode.
