Try First or Install Directly

When facing a brand-new operating system, the biggest concerns are often: “What if I don’t like it after installing?” “Will it mess up my Windows?” “Will my hardware work properly?” The good news is that Ubuntu offers several zero-risk or low-risk ways to try it out, letting you fully explore Ubuntu 26.04 without affecting your existing system.

This article provides a detailed comparison of three main approaches — Live USB trial, virtual machine experience, and direct installation — to help you find the one that best fits your current situation.

Live USB Trial Mode

What is a Live USB

A Live USB writes the complete Ubuntu system onto a USB drive, then boots the computer from the USB drive directly into the Ubuntu desktop. The entire system runs in memory and makes no changes to your hard drive. After shutting down and removing the USB drive, your computer returns to its original state as if nothing happened.

Steps to Create a Live USB

  1. Download the Ubuntu 26.04 LTS ISO image (~5GB) from ubuntu.com/download 
  2. Prepare an 8GB or larger USB drive (all data on the drive will be erased)
  3. Use one of the following tools to write the ISO to the USB drive:
    • Windows users: Rufus  or balenaEtcher  recommended
    • macOS users: balenaEtcher  recommended
    • Linux users: GNOME Disks’ built-in “Restore Disk Image” feature, or the dd command
  4. Restart your computer, enter BIOS/UEFI settings, and set the USB drive as the first boot device
  5. After booting, select “Try Ubuntu”

What You Can Do with a Live USB

In the Live USB environment, you can perform the following to thoroughly evaluate Ubuntu:

  • Browse the web and test whether Wi-Fi works
  • Open the file manager to check if existing hard drive partitions are readable
  • Test Bluetooth, webcam, microphone, speakers, and other hardware
  • Adjust screen resolution and scaling
  • Try installing and running a few common applications
  • Connect printers, external monitors, and other peripherals
Warning

In Live USB mode, no changes are saved. Software you install, files you download, settings you change — everything disappears after shutdown. This is purely an “experience mode” and is not suitable for actual work. If you need a persistent environment, choose a virtual machine or direct installation.

Limitations of Live USB

  • Slower speed — System performance depends on the USB drive’s read/write speed. USB 2.0 drives will feel noticeably sluggish; USB 3.0 or faster is recommended
  • No data persistence — Every boot starts from a fresh state
  • Higher memory usage — The system runs entirely in RAM. If your computer only has 6-8GB of memory, the experience will be affected
  • Some drivers may not load — Especially certain NVIDIA GPU drivers that require additional installation

Virtual Machine Experience

Why a Virtual Machine is the Best Way to Learn

A virtual machine (VM) simulates a “virtual computer” within your current operating system, and Ubuntu runs inside it. It combines the advantages of safety and persistence:

  • Complete isolation — Operations inside the VM do not affect the host system
  • Data persistence — All changes are saved after shutdown
  • Snapshot feature — Take snapshots before risky operations and roll back with one click if something goes wrong
  • Easy to remove — Just delete the VM files when you no longer need it
SoftwarePlatformCostFeatures

VMware WorkstationWindows / LinuxFree for personal useBetter performance than VirtualBox, better 3D acceleration
VMware FusionmacOSFree for personal useTop commercial choice on macOS
GNOME BoxesLinuxFree & open sourceThe simplest VM manager on Linux
UTMmacOS (including Apple Silicon)Free & open sourceBest choice for Apple Silicon Macs
Parallels DesktopmacOSPaidBest performance on macOS, but requires a license

For a smooth VM experience, allocate the following resources:

ResourceMinimumRecommended
CPU cores2 cores4 cores
Memory4 GB8 GB
Disk space25 GB50 GB (dynamically allocated)
Video memory64 MB128 MB
3D accelerationOffOn (if host supports it)
Tip

When creating a virtual machine, choose the dynamically allocated disk format. This way, the virtual disk file only takes up as much space as is actually used, rather than claiming the full allocated size upfront. For example, if you allocate 50GB but only use 15GB, the virtual disk file will be only 15GB in size.

Limitations of Virtual Machines

  • Performance overhead — CPU and memory performance is about 70-90% of native, but disk I/O and graphics performance take a bigger hit
  • Limited 3D graphics — Not suitable for gaming or 3D modeling and other graphics-intensive tasks
  • Cannot test real hardware — Wi-Fi, Bluetooth, fingerprint readers, and other hardware cannot be tested in a VM
  • Requires sufficient host resources — The host machine needs at least 12GB of memory to run both the host OS and the VM simultaneously

Direct Installation to Disk

Who Should Install Directly

If you meet most of the following conditions, you can install directly to disk:

  • You have thoroughly experienced Ubuntu via Live USB or a virtual machine
  • You have confirmed that your hardware (especially Wi-Fi and GPU) is compatible with Ubuntu
  • Your daily work does not depend on Windows/macOS-exclusive software
  • You have a habit of backing up important data
  • You are mentally prepared to learn a new system from scratch

Choosing an Installation Method

When installing directly, the Ubuntu installer offers the following options:

Installation MethodDescriptionRisk
Erase entire diskDeletes all data on the disk, installs only UbuntuNo risk (but all existing data is lost)
Install alongside existing OSAutomatically adjusts partitions, preserves Windows/other systemsMedium (involves partition resizing)
Manual partitioningFully customized partition layoutHigher (requires partition knowledge)
Note

The Ubuntu 26.04 installer has been completely redesigned. The entire installation process typically takes only 10-15 minutes. The installer automatically detects your hardware and configures the timezone, language, and network. Even first-time Linux users should not encounter major difficulties by following the on-screen instructions.

For most Linux newcomers, we recommend the following gradual approach:

Step 1: Quick Live USB Experience (30 minutes)

Create a bootable USB drive and boot from it to experience the Ubuntu desktop. Focus on:

  • Whether the interface appeals to you visually
  • Whether Wi-Fi and basic hardware work properly
  • Whether the overall workflow is acceptable

Step 2: In-Depth Learning with a Virtual Machine (1-2 weeks)

Install Ubuntu in a virtual machine and start using it for real:

  • Install the software you use daily (browser, office suite, messaging apps, etc.)
  • Learn basic terminal commands
  • Try customizing the desktop appearance and keyboard shortcuts
  • Practice searching for and solving problems as they arise

Step 3: Install on Real Hardware After Confirming Satisfaction

Once you can complete most of your daily work in the virtual machine, consider installing on real hardware:

  • Start with a dual-boot setup to retain the ability to fall back to Windows
  • Gradually shift your work to Ubuntu
  • When you find that you rarely boot Windows anymore, consider making Ubuntu your only system
Tip

Don’t rush to go all-in. Switching operating systems is a process that requires adaptation, involving software replacement, workflow adjustment, and building new habits. Give yourself 2-4 weeks of transition time, and keep a fallback option (dual-boot or VM) during this period — it will make the whole process much more enjoyable.

FAQ

Q: Will a Live USB damage my computer?

No. A Live USB runs entirely in memory and does not write anything to your hard drive (unless you manually click to install).

Q: Is Ubuntu in a VM different from a real installation?

Functionally, they are identical — only performance differs. Ubuntu in a VM is a real Ubuntu system, and everything you learn in the VM can be applied directly on real hardware.

Q: My computer only has 8GB of RAM. Can it run a VM?

Yes, but the experience will be tight. Allocate 4GB to the VM, leaving 4GB for the host. If the host is Windows, both sides will be sluggish with this setup. If possible, 16GB of RAM provides a much better experience.

Q: Can I get Windows back after installing directly?

If you chose “Install alongside existing OS” (dual-boot), Windows remains intact. If you chose “Erase entire disk,” Windows will be completely removed and can only be restored by reinstalling Windows.
