How to Install Ubuntu and Remove Windows Without a USB

Many users are interested in exploring Linux distributions, such as Ubuntu, to improve their computer's performance and security. However, the traditional installation process usually requires a USB drive or other installation media, which can be inconvenient. In this article, we will explore an alternative method to install Ubuntu and remove Windows, even without a USB drive. Please note that this method may vary based on your specific hardware and software environments. Always ensure you have backed up your data before proceeding.

Understanding the Installation Process

To install a new operating system on a computer that currently has Windows installed, the installation process follows several steps. The most crucial step is to load the operating system's installation media into the computer's memory during the boot process. This installation media typically comes in the form of a USB drive or a CD/DVD. The installation media contains the necessary files to install the new system and overwrite the existing one, including Windows.

Using a Virtual Machine

While you cannot install Ubuntu directly on the physical drive without a bootable USB, you can use a virtual machine (VM) to achieve the desired result. A virtual machine effectively creates a simulation of a computer within your existing operating system. By setting up a VM, you can install Ubuntu without affecting your current installation of Windows.

Step 1: Install a Virtualization Software

First, you need to install a virtualization software on your existing Windows system. Popular choices include:

VirtualBox: An open-source software that supports multiple operating systems and is available for Windows, macOS, and Linux. Vmware Workstation: A powerful and feature-rich virtualization software. Hyper-V: A built-in virtualization platform that comes with Windows 10 Pro and later versions.

Step 2: Create a New Virtual Machine

Once you have the virtualization software installed, create a new virtual machine. This process involves specifying the virtual machine's settings, such as the amount of memory (RAM) it will use and the type of disk image you want to create. A virtual machine can use either a virtual hard disk (VHD) or a virtual hard drive (VDI). For this method, a VHD is preferable as it allows you to install Ubuntu directly on the VHD without needing a USB.

Step 3: Install Ubuntu on the Virtual Machine

With the virtual machine created, you can now install Ubuntu. The installation process is similar to installing it on a physical drive, but all changes will be made within the virtual environment. Follow the on-screen instructions to complete the installation. During the installation, you can select the option to erase the virtual disk completely, effectively removing any existing partition data.

Step 4: Migrate the Virtual Disk to a Physical Drive

After installing Ubuntu in the virtual environment, you can move the virtual disk from the VM to your physical drive. This process involves creating a VHD file on your physical drive and copying the files from the virtual machine's VHD to this new file. Once the transfer is complete, you can boot from the physical drive and install Ubuntu directly without needing a USB. Be cautious during this step as data loss can occur if not done correctly.

Alternatives to Consider

While the virtual machine approach is a viable solution, it may not suit everyone. For those looking for a more direct method, consider the following alternatives:

CD/DVD Installation Media: If you have a spare CD/DVD, you can burn an Ubuntu installation ISO to it and use it to install the OS. However, this requires a physical DVD/CD drive, which may not be available on all modern computers. Network Installation (PXE): If your computer’s network interface card (NIC) and network hardware support PXE (Preboot Execution Environment), you can set up a network boot server to install Ubuntu over the network. This method requires setting up a network boot server and ensuring that your PC supports PXE boot.

Conclusion

While it is not possible to install Ubuntu and remove Windows entirely without a USB or another form of installation media under standard conditions, the virtualization approach offers a viable workaround for those in need. With the right tools and knowledge, you can achieve your goal of installing Ubuntu and removing Windows from your system.

Key Takeaways

Use a virtual machine for a safe and easy installation of Ubuntu. Create a VHD file and migrate it to a physical drive for a more direct installation. Consider other alternatives if you do not have a spare USB drive or PXE network boot setup.
