Ubuntu

Ubuntu is the most widely used Linux distribution, developed by Canonical. It ships with the GNOME desktop environment, a graphical software center, and a full suite of preinstalled applications. Ubuntu is free, open source, and available for desktops, servers, cloud deployments, and IoT devices.

What it does

Download the ISO from ubuntu.com, write it to a USB drive using Rufus or balenaEtcher, and boot from it. The installer walks you through partitioning, language, timezone, and user setup. You can install Ubuntu alongside Windows in a dual boot configuration or replace the existing operating system entirely. The entire process takes about 15 to 20 minutes on a modern machine.

Once installed, software management is handled through Ubuntu Software (a graphical app store) or the terminal with apt and snap. The apt package manager pulls from Ubuntu's repositories, while Snap packages run in sandboxed containers and update automatically. LTS (Long Term Support) releases receive security updates for five years, which makes them a safe choice for machines you do not want to reinstall frequently.

Hardware support works out of the box for most components. For NVIDIA graphics cards, open Settings > Software & Updates > Additional Drivers and select the proprietary driver. Wi-Fi, Bluetooth, printers, and peripherals are typically detected automatically during installation.

Who it is for

I recommend Ubuntu as the first Linux distribution for anyone switching from Windows or macOS. The installation is straightforward, the community is enormous, and virtually every Linux tutorial on the internet assumes Ubuntu. LTS releases are stable enough for daily use without constant tinkering. If you need a Linux server, Ubuntu Server is equally well supported. It is not the lightest or the most customizable distribution out there, but it is the one where you will spend the least time troubleshooting and the most time actually getting work done.
