Let's think about it this way for a second
There are three options. (1) WSL (Windows Subsystem for Linux): run a Linux terminal right inside Windows like any other app — no dual boot needed. (2) Virtual Machine (VirtualBox, VMware): run Linux inside Windows/macOS as a 'computer inside a computer' — delete it and you just delete that one VM. (3) Live USB: put Linux on a USB drive and boot from it, without touching your hard disk at all. For beginners, starting with WSL or a VM is recommended.
Let's connect this to a real-world scenario
If you're on Windows 10/11, WSL2 is the easiest route — open PowerShell (admin) and install it with a single command. Mac/Linux native users can jump straight into the terminal (since macOS/Linux are themselves Unix-based). Every command in this tutorial works whether you're on WSL, a VM, or a cloud server (VPS) — all you need is a terminal you can open.
Let's try it together in the terminal
# Windows PowerShell (as Administrator)
wsl --install
# After restart, open "Ubuntu" from Start menu
# Set a username and password when promptedA terminal window opens showing a prompt in the form username@hostname:~$.5-minute try-it
Install WSL (Windows) or a VM. Open the terminal and note down what the prompt looks like.
A quick word of caution
Don't attempt dual boot (wiping Windows to install Linux) at this stage as a beginner. Consider it only after you're comfortable with WSL/VM.
