Linux for Absolute Beginners: Install Your First Distro in 30 Minutes
A practical, no-jargon walkthrough of choosing a Linux distribution, building a bootable USB, booting the live session and completing a safe first install in about half an hour.
Installing Linux is not the weekend project it used to be. On a normal laptop with working Wi-Fi, you can go from a blank USB stick to a running desktop in roughly thirty minutes, and most of that is spent watching progress bars. The one step that genuinely trips people up is the disk part, so that is where this walkthrough slows down and explains everything.
The plan is simple: back up, pick a distribution, write it to a USB stick, boot the live session to test your hardware, then install. If you want to keep Windows, you can, and we will cover that case in detail.
Before You Touch Anything
Ten minutes of preparation saves an evening of regret. Do these first:
- Back up your files. Copy anything irreplaceable to an external drive or cloud storage. Partitioning tools are reliable, but "reliable" is not "infallible", and a backup costs you nothing.
- Check free space. Linux wants roughly 25 GB for a comfortable desktop install; 40 GB or more if you plan to keep it long term.
- Write down your Wi-Fi password. You will need it during the live session, and hunting for it after reboot is annoying.
- On Windows, disable Fast Startup and back up your BitLocker recovery key if the drive is encrypted. Skip this and the installer may not see your Windows partition at all.
- Grab an 8 GB USB stick. Everything on it will be erased, so empty it first.
- Plug in the charger. A laptop that dies mid-install is a bad afternoon.
Pick a Distribution You Won't Fight With
For a first install, choose something with a large community and a graphical installer. All four of these are friendly, well documented and stable:
- Linux Mint — the classic recommendation for people coming from Windows. Familiar layout, sensible defaults, excellent hardware support.
- Ubuntu LTS — the biggest community, the most answers online, and long support windows. The long-term support releases are the safe bet.
- Fedora Workstation — newer software, clean GNOME desktop, good if you like things current rather than conservative.
- Pop!_OS — Ubuntu underneath with a tidier desktop and good laptop power management.
Download the ISO from the project's official website. While you are there, grab the checksum file and verify it if you can — a corrupted download is a common cause of mysterious boot failures. On Linux use sha256sum file.iso; on Windows, certutil -hashfile file.iso SHA256.
Create the USB Installer
You need one tool and one ISO. The ISO is a complete image of the installer; the tool copies it onto the stick in a way the firmware can boot.
On Windows
- Install Rufus (portable version is fine) or balenaEtcher.
- Select your USB stick under "Device" — double-check the size so you don't wipe the wrong drive.
- Choose the ISO with "Select".
- Leave the partition scheme on GPT and target UEFI; pick MBR only for an older machine that boots in legacy mode.
- Click Start, accept the warning, and wait for the write and verification to finish.
On Linux or macOS
balenaEtcher works on both and is hard to misuse. If you prefer the terminal, find your stick with lsblk (Linux) or diskutil list (macOS), unmount it, then write the image with dd:
sudo dd if=~/Downloads/distro.iso of=/dev/sdX bs=4M status=progress oflag=sync
Replace sdX with your stick's device name, not a partition number. Choosing the wrong device here erases that device, so read the output of lsblk twice.
Boot From the Stick
Restart the machine and tap the boot menu key during the manufacturer logo — usually F12, F10, F9, Esc or Del, depending on the brand. Select the USB entry, normally labelled with the stick's name or "UEFI: ...".
If nothing happens, you need to change firmware settings. Two common culprits: Secure Boot, and the boot order. Mint, Ubuntu, Fedora and Pop!_OS all support Secure Boot, so you can usually leave it on. If the stick is simply not listed, disable Secure Boot temporarily, boot the installer, and turn it back on afterwards if you want.
You will land on a menu offering to try the system or install it. Choose "Try" first. This runs Linux from the USB without touching your disk. Test the Wi-Fi, sound, touchpad, screen brightness keys and suspend. Five minutes here tells you whether installation is a good idea today.
The Installation Itself
Launch the installer from the desktop and work through the language, keyboard and timezone screens. When asked about third-party software, say yes — that installs Wi-Fi firmware and media codecs you will want later.
Then comes the important screen. You get three realistic choices:
- Erase disk and install. Wipes everything. Perfect for a spare machine or a dedicated Linux laptop.
- Install alongside Windows. Keeps Windows and gives Linux part of the free space. The simplest dual-boot route.
- Something else. Manual partitioning. Skip this unless you have specific plans.
For dual booting, shrink your Windows partition from Windows using Disk Management first, leaving the freed space unallocated. Then let the installer use it. Do not touch the existing EFI system partition — it is shared and Windows needs it.
Set a username and a strong password, keep the "log in automatically" box unticked on a laptop, and start the install. It takes ten to twenty minutes. When it finishes, remove the USB stick and reboot.
Your First Boot
Update before you customise anything. Open a terminal and run:
sudo apt update && sudo apt upgrade
On Fedora the equivalent is sudo dnf upgrade --refresh. Then open the driver or additional-drivers tool if your distro has one, and install any suggested graphics or Wi-Fi drivers. Enable the firewall — sudo ufw enable on Ubuntu-based systems. Finally, set up Timeshift or your distro's snapshot tool so you can roll back before you experiment.
If Something Goes Wrong
Keep that USB stick. It doubles as a rescue disk, and it can repair a bootloader or copy files off a machine that will not start. If a boot fails, note the exact error text, search for it, and ask in the distro's forum or community chat with your hardware details. Most first-install problems — no Wi-Fi, black screen, Windows not appearing in the boot menu — are known issues with known fixes.
And if the install goes badly enough that you want to start over, you can. Reinstalling takes twenty minutes. Nothing about this is permanent, which is exactly why it is worth trying.
