Introduction

Ubuntu has become one of the most popular Linux distributions worldwide, favored by developers, students, professionals, and privacy-conscious users alike. Its stability, open-source nature, and strong community support make it an ideal choice for both newcomers and seasoned Linux users. However, installing Ubuntu correctly is not as simple as downloading an ISO and clicking Next. A flawed installation can lead to data loss, boot failures, driver incompatibilities, or even compromised system security.

This is why trust matters. Not every guide online is accurate, up-to-date, or safe. Many tutorials skip critical steps, assume prior knowledge, or promote outdated tools. Some even bundle third-party software or recommend disabling secure boot without explaining the risks. In this comprehensive guide, we present the top 10 how to install Ubuntu methods you can trusteach verified through real-world testing on multiple hardware configurations, reviewed for security best practices, and aligned with the latest Ubuntu LTS release.

Whether youre installing Ubuntu on a brand-new PC, replacing Windows, dual-booting with another OS, or setting up a server, this guide ensures you follow only the most reliable, secure, and effective procedures. No fluff. No guesswork. Just clear, trusted steps that work.

Why Trust Matters

Installing an operating system is a foundational act. It determines how your computer functions, what software you can run, and how secure your data remains. A single missteplike selecting the wrong partition, disabling UEFI incorrectly, or using a corrupted ISOcan render your system unusable. Worse, following unverified instructions may expose you to malware, backdoors, or data leaks disguised as helpful tools.

Many online tutorials are written by enthusiasts who may not fully understand the underlying architecture of UEFI vs. BIOS, partition tables, or bootloader configurations. Others are outdated, referencing Ubuntu 18.04 or even 16.04, which lack support for modern hardware features like NVMe drives, TPM 2.0, or secure boot. Some recommend third-party tools that inject unwanted packages or modify system files without transparency.

Trusted installation methods are characterized by:

• Direct sourcing from official Ubuntu documentation or canonical partners
• Clear distinction between UEFI and Legacy BIOS modes
• Explicit warnings about data loss and backup procedures
• Verification of ISO checksums before installation
• Use of standard, unmodified installation media
• Step-by-step guidance that avoids assumptions about user expertise

When you trust the source, you trust the outcome. This guide prioritizes methods endorsed by the Ubuntu project, tested on real hardware, and validated by system administrators and security researchers. Each of the top 10 methods below meets these criteria. You will not find shortcuts that bypass security, nor will you encounter advice that assumes you already know how to use fdisk or gparted. Every step is explained with clarity and precision.

By following these trusted methods, you avoid the most common pitfalls: failed boot entries, encrypted home directories that cant be recovered, GRUB corruption, and incompatible drivers. You also ensure your system remains upgradable, secure, and compatible with future Ubuntu releases.

Top 10 How to Install Ubuntu

FAQs

Can I install Ubuntu without a USB drive?

Yes, but only in specific cases. You can use PXE network booting, WSL2 on Windows, or cloud platforms like AWS. For most users, however, a USB drive is the simplest and most reliable method.

Do I need to back up my data before installing Ubuntu?

Always. Even if you choose Erase disk and install Ubuntu, the process will delete all existing data. If youre dual-booting, Windows partitions may still be at risk if misconfigured. Back up critical files to an external drive or cloud storage before proceeding.

Is Ubuntu safe from viruses?

Ubuntu is significantly more secure than Windows due to its permission model, package management, and lack of widespread malware targeting Linux desktops. However, no system is immune. Always download software from official repositories (apt), avoid running commands from untrusted sources, and keep your system updated.

Whats the difference between Ubuntu Desktop and Server?

Ubuntu Desktop includes a graphical interface (GNOME), web browser, and productivity apps. Ubuntu Server is command-line only and optimized for headless operation, web servers, databases, and containers. Both use the same kernel and package base.

Why does my computer boot directly into Windows after installing Ubuntu?

This usually happens if the bootloader (GRUB) was installed to the wrong partition or if UEFI firmware prioritizes Windows Boot Manager. Boot into UEFI settings and change the boot order to prioritize Ubuntu. Alternatively, use a live USB and run sudo grub-install /dev/sdX (replace X with your disk identifier).

Can I install Ubuntu on an old PC with 2GB of RAM?

Technically yes, but performance will be poor. Ubuntu Desktop requires at least 4GB RAM for a usable experience. For older hardware, consider lightweight alternatives like Lubuntu or Xubuntu, which are officially supported Ubuntu flavors with lower system requirements.

What happens if I disable Secure Boot?

Secure Boot prevents unsigned bootloaders from running. Disabling it allows Ubuntu to boot, but reduces system security. Modern Ubuntu versions support Secure Boot out of the box. Only disable it if you encounter boot errorsthen re-enable it after confirming Ubuntu boots correctly.

How do I know if my Ubuntu ISO is corrupted?

Always verify the SHA256 checksum. On Linux/macOS, use sha256sum filename.iso. On Windows, use PowerShell: Get-FileHash -Algorithm SHA256 filename.iso. Compare the output to the value listed on ubuntu.com. If they dont match, download the ISO again.

Can I upgrade Ubuntu without reinstalling?

Yes. Ubuntu supports in-place upgrades from one LTS version to the next (e.g., 22.04 to 24.04). Use sudo do-release-upgrade in the terminal. Always back up your data before upgrading.

Is Ubuntu free to use commercially?

Yes. Ubuntu is completely free for personal, educational, and commercial use. Canonical offers paid support services, but the operating system itself has no licensing fees.
