How to Install Ubuntu Safely on Any Computer

Ubuntu offers a clean, secure, and flexible desktop experience. It works well for daily tasks, software development, education, and business use.

However, installing a new operating system requires careful planning. A wrong storage choice could erase important files. You may also face boot, driver, or internet problems.

This guide explains each step in simple language. You will learn how to prepare your computer, create installation media, configure storage, and complete the setup safely.

Ubuntu provides a guided installer for desktop users. The installer handles most technical tasks automatically. You can also test Ubuntu before changing your computer.

Choose the Right Ubuntu Version

Start by choosing the correct Ubuntu edition.

Ubuntu Desktop suits laptops and personal computers. It includes a graphical interface, web browser, file manager, and common desktop tools.

Ubuntu Server targets servers, cloud systems, and command-line environments. Most beginners should choose Ubuntu Desktop.

You will usually see two main release types:

• Long-Term Support releases
• Interim releases

Long-Term Support releases focus on stability and extended maintenance. They suit work computers, schools, and long-term projects.

Interim releases include newer features. However, they receive support for a shorter period.

Ubuntu 26.04 LTS is the current desktop LTS release in Canonical’s official 2026 installation documentation. Older supported LTS versions may also remain available.

Check Your Computer Before Installation

Your computer must meet Ubuntu’s basic hardware needs.

Canonical’s current desktop installation tutorial recommends a computer with at least 25 GB of storage. You also need a USB drive for the installer.

For smoother daily performance, consider these practical targets:

• A modern 64-bit processor
• At least 4 GB of memory
• At least 25 GB of free storage
• A USB port
• A stable internet connection
• Access to your BIOS or UEFI settings

More memory helps when using browsers, development tools, or several applications.

Check your computer model before downloading Ubuntu. Most modern Intel and AMD computers use the 64-bit desktop image.

Back Up Your Important Files

Always create a backup before changing disk partitions.

Copy your documents, photos, passwords, and project files. Store them on an external drive or trusted cloud service.

Do not keep the only backup on the computer you plan to modify.

Confirm that your backup opens correctly. A backup provides little value when its files cannot be restored.

You should also save:

• Browser bookmarks
• Software licence details
• Email archives
• Wi-Fi passwords
• Recovery keys
• Important application settings

Disk changes can cause permanent data loss. Careful preparation protects your information.

Download Ubuntu from the Official Source

Download the Ubuntu ISO image from Canonical’s official website.

An ISO file contains the complete installation system. Do not open it like a normal application. You must write it to a USB drive using an image-writing tool.

Avoid unofficial download websites. They may offer outdated, modified, or unsafe files.

Advanced users can verify the downloaded ISO. Canonical provides SHA-256 and GPG verification instructions. These checks confirm file integrity and authenticity.

Create a Bootable USB Drive

Use a USB drive that holds the Ubuntu ISO image.

The writing process erases everything on the USB drive. Move existing files elsewhere before starting.

Ubuntu’s official desktop tutorial recommends an image-writing tool such as balenaEtcher. It works on Windows, macOS, and Linux.

Follow these steps:

1. Insert the USB drive.
2. Open your chosen image-writing tool.
3. Select the Ubuntu ISO file.
4. Select the correct USB drive.
5. Start the writing process.
6. Wait until verification finishes.
7. Safely remove the USB drive.

Do not copy the ISO directly onto the USB. A copied ISO will not usually create bootable installation media.

The software must write the image in a bootable format.

Boot Your Computer from the USB Drive

Insert the bootable USB into the target computer.

Restart the computer and open its boot menu. Many systems use F12 during startup. Others use Esc, F2, F9, F10, or Delete.

The exact key depends on the manufacturer.

Select the USB device from the boot menu. Ubuntu should then load its welcome screen.

Canonical notes that some computers detect installation media automatically. Others require manual selection through the boot menu.

Disable Fast Startup in Windows when the USB fails to appear. You may also need to adjust the boot order inside UEFI settings.

Avoid changing unknown firmware settings. Record each change before saving it.

Test Ubuntu Before Installing

Ubuntu usually lets you test the system first.

This option runs Ubuntu from the USB without installing it. It helps you check hardware compatibility.

Test these features:

• Wi-Fi
• Bluetooth
• Sound
• Keyboard
• Touchpad
• Webcam
• External display
• Screen brightness
• Sleep and wake
• USB ports

Open a few applications. Play audio and connect to the internet.

A live session may run slower than an installed system. The USB drive limits its speed.

Testing reduces surprises after installation. It also reveals possible driver problems.

Start the Installation Process

Open the installer from the Ubuntu desktop.

Choose your language and keyboard layout. Test special keys before continuing.

Connect to the internet when possible. The installer may download updates and useful drivers.

You may see options for:

• A standard installation
• A minimal installation
• Third-party software
• Media format support
• Additional drivers

A standard installation suits most users. It includes common desktop applications.

A minimal setup installs fewer applications. It works well when you prefer a clean system.

Third-party software may improve support for graphics cards, Wi-Fi devices, and media formats.

Choose the Correct Disk Option

This step requires the most attention.

The installer may offer several storage choices. Each choice affects your existing data.

Installation Option	Best For	Main Risk
Erase disk and install	A dedicated Ubuntu computer	Deletes all existing data
Install alongside another system	Windows and Ubuntu users	Partition changes may cause problems
Manual partitioning	Experienced users	Wrong choices can erase data
Virtual machine	Testing without disk changes	Lower performance

Choose “Erase disk” only when you want Ubuntu as the only operating system.

Choose an alongside option when you want dual boot. This setup lets you select Windows or Ubuntu during startup.

Manual partitioning offers more control. However, beginners should avoid it unless they understand partitions, file systems, and boot loaders.

Review the selected disk carefully. Computers with several drives can cause confusion.

Understand Dual Boot Installation

Dual boot keeps Ubuntu and another operating system on one computer.

Before starting, free enough storage inside Windows. Use Windows Disk Management to shrink the main partition safely.

Do not delete Windows recovery partitions.

Disable Windows Fast Startup. It can leave shared drives in an unsafe state.

Save your BitLocker recovery key when device encryption is active. Firmware or boot changes may trigger a recovery request.

During installation, choose the option that installs Ubuntu beside Windows. Confirm the proposed disk layout before continuing.

After installation, a boot menu should appear. It lets you choose either operating system.

Follow a trusted Ubuntu installation guide when your hardware needs special partition or boot settings.

Create Your User Account

The installer will ask for your name, computer name, username, and password.

Choose a strong password. Use a unique combination of words, numbers, and symbols.

Do not reuse an email or banking password.

You may choose automatic login. However, password-based login offers better protection.

Write down your username. Linux commands and file locations often use it.

The computer name identifies your device on local networks. Choose a simple name without sensitive details.

Finish the Installation

The installer will copy files and configure the operating system.

Do not turn off the computer during this process.

Installation speed depends on your storage drive, USB speed, internet connection, and hardware.

The installer will ask you to restart after completion.

Remove the USB drive when prompted. Then press Enter or continue the restart.

Your computer should load the installed Ubuntu system.

Open the boot menu when the system returns to the installer. Select the internal drive or remove the USB.

Update Ubuntu After Installation

Install available updates before adding many applications.

Open Software Updater from the application menu. Review the updates and install them.

You can also use the terminal:

sudo apt update

sudo apt upgrade

The first command refreshes package information. The second installs available upgrades.

Restart the computer when Ubuntu installs kernel or major system updates.

Regular updates deliver security fixes, bug repairs, and hardware improvements.

Ubuntu includes built-in update tools. Long-Term Support releases also provide an extended maintenance path for stable systems.

Check Drivers and Hardware

Ubuntu supports many devices automatically. Some hardware needs an additional driver.

Open the Software and Updates application. Then select the Additional Drivers section.

Ubuntu may list recommended drivers for:

• NVIDIA graphics cards
• Wireless adapters
• Special chipsets
• Other proprietary hardware

Choose the recommended option unless you need a specific version.

Restart after installing a graphics driver.

Avoid downloading random Linux drivers from unknown websites. Use Ubuntu repositories or the hardware manufacturer’s official resources.

Install Essential Applications

Ubuntu includes useful software for browsing, file management, and basic tasks.

You can install more applications through App Center or the terminal.

Common choices include:

• A password manager
• A media player
• A code editor
• A backup tool
• A communication app
• A graphics editor
• A cloud storage client

Install only the software you need. Too many background applications can slow startup.

Check each application’s official source. Avoid untrusted package files.

Ubuntu supports several package formats, including DEB, Snap, and other container-based options. Choose official or well-maintained packages.

Improve Security After Installation

A fresh installation still needs basic security settings.

Use a strong account password. Lock the screen when leaving your computer.

Install updates regularly. Remove unused software and browser extensions.

Enable the firewall with these terminal commands:

sudo ufw enable

sudo ufw status

The firewall helps control incoming network connections.

Use full-disk encryption when you store sensitive files. Encryption protects data if someone steals the computer.

However, losing the password or recovery information may block access permanently.

Keep important recovery details in a secure location.

Fix Common Installation Problems

Some systems may not boot from the USB.

Recreate the USB and verify the ISO file. Try another USB port or drive.

A black screen may relate to graphics hardware. Booting with a safe graphics option can help during installation.

Missing Wi-Fi often indicates an unsupported or proprietary adapter. Use an Ethernet connection or phone tethering during setup. Then check Additional Drivers.

A missing operating system after dual boot may require a boot-order change. Open UEFI settings and place Ubuntu or the correct boot manager first.

Do not format partitions while troubleshooting. Identify the problem before changing disk structures.
