How do I install Linux on my first custom-built PC?

The basic process is: choose a Linux distribution, download its ISO file from the official website, use another working computer to write that ISO to a USB drive, then plug the USB into your new PC and boot from it. Programs such as Rufus on Windows or balenaEtcher on Linux and macOS can create the installer. You’ll generally need a USB drive with at least 4–8 GB of space.

If you’re unsure which distribution to pick, Linux Mint or Zorin OS are both approachable for someone coming from Windows. Download the ISO and create a bootable USB, then start the PC from that drive. Most modern motherboards will detect it automatically, but you may need to open the boot menu or firmware settings and select the USB manually.

Since this is a brand-new PC, assume it has no operating system yet. You’ll need access to another working computer to download the ISO and prepare the USB, or you can ask someone you trust to make the installer for you. After installation, it’s a good idea to read beginner guides, learn the basics gradually, and keep backups before experimenting with system commands.

Try the live environment before installing. Many Linux installers let you boot into a temporary desktop directly from the USB, so you can check whether your graphics, network, sound, and other hardware work properly. If everything looks good, use the installation shortcut on the desktop. Follow the distribution’s official installation guide rather than changing firmware settings blindly; settings such as Secure Boot can often remain enabled unless the chosen distribution specifically requires otherwise.
