How to Install Ubuntu from Windows

You have two primary paths: dual-boot installation or Windows Subsystem for Linux (WSL). Dual-boot creates a separate Ubuntu partition on your drive, requiring you to choose your operating system at startup. WSL runs Ubuntu directly within Windows without rebooting. WSL is faster for development work and easier to set up, while dual-boot gives you a dedicated Ubuntu environment with full system resources. Consider your workflow and hardware before deciding. WSL works on Windows 10 version 2004 and later, including Windows 11. Dual-boot requires free disk space and basic partitioning knowledge.

WSL is the quickest method for most users. Open PowerShell as administrator and run 'wsl --install'. This command downloads and installs Ubuntu automatically. Windows will prompt you to restart your computer. After restarting, Ubuntu launches automatically and asks you to create a username and password. These credentials are separate from your Windows login. Once setup completes, you have a full Ubuntu terminal environment. You can launch it anytime from the Start menu or by typing 'wsl' in PowerShell. WSL gives you access to Linux package managers like apt, making it simple to install development tools and applications.

For dual-boot, first create a bootable Ubuntu USB drive using a tool like Rufus or Balena Etcher on another computer. Download the Ubuntu ISO file from the official Ubuntu website. Insert the USB drive into your Windows machine and restart. Enter your BIOS or UEFI settings by pressing the appropriate key during startup, usually Delete, F2, or F12. Change the boot order to prioritize USB devices. Save and exit. Your computer boots from the USB drive. Select 'Install Ubuntu' from the menu. The installer guides you through language selection, keyboard layout, and network configuration. When prompted for installation type, choose 'Something Else' to manually partition your disk.

Disk partitioning determines how space is allocated between Windows and Ubuntu. You need at least 20-30 GB free space for Ubuntu. In the Ubuntu installer's partition screen, select your Windows drive and shrink it to create unallocated space. Create a new partition for Ubuntu with at least 20 GB. You may also create a separate swap partition, though modern systems often skip this. Assign the Ubuntu partition to the root mount point '/'. Carefully review your partition layout before confirming, as mistakes can damage your Windows installation. The installer then formats the Ubuntu partition and copies system files, which takes several minutes depending on your drive speed.

After installing Ubuntu, you can set up development environments like PyCharm. In Ubuntu terminal, update your package manager with 'sudo apt update' and 'sudo apt upgrade'. Install Java, which PyCharm requires, using 'sudo apt install default-jdk'. Download PyCharm Community Edition from the JetBrains website or install it via snap with 'sudo snap install pycharm-community --classic'. The snap method is simpler and handles updates automatically. Once installed, launch PyCharm from your applications menu or terminal. Configure your Python interpreter by pointing PyCharm to your Ubuntu Python installation. You can now create and run Python projects directly in Ubuntu.

After installation completes, your computer boots into a GRUB menu showing Ubuntu and Windows options. Select your preferred system. You can modify the default boot choice by editing GRUB configuration later. Install essential development tools with 'sudo apt install build-essential'. Update your system regularly using 'sudo apt update && sudo apt upgrade'. Customize your desktop environment, install your preferred applications, and configure system settings. For WSL users, explore Windows Terminal for a better command-line experience. Both installation methods give you full access to Ubuntu's software repositories and development tools.

If your computer won't boot from USB, verify the USB drive was created correctly and check your BIOS boot settings. Some systems require disabling Secure Boot. If Ubuntu installation freezes, try booting with 'nomodeset' option from the GRUB menu. For WSL, ensure virtualization is enabled in your BIOS. If you encounter disk space errors during installation, check that you allocated enough free space before starting. Windows 11 users should verify their system meets WSL requirements. If dual-boot fails to show the GRUB menu, you may need to repair your boot loader using Ubuntu's recovery tools. Consult Ubuntu community forums for specific error messages.
