Live USB session
Boot Linux from removable media without installing it. This is the best way to test Wi-Fi, sound, displays, sleep, keyboard, and touchpad on the actual computer.

Safe Linux Live-USB & Install Guide
Test Linux on real hardware without treating your everyday computer like an experiment.
Choose the safest test method
Virtual machine
Run Linux in a window inside Windows or macOS. It is excellent for exploring the desktop, but it cannot prove that every physical device will work after installation.
Separate test computer or drive
Keep experimentation away from the computer you depend on. A spare machine or separate internal drive reduces partitioning complexity.
Before you download anything
- Back up documents, photos, browser data, and license information.
- Test that the backup opens from a different device or drive.
- Create Windows recovery media and record the edition installed.
- Save BitLocker or device-encryption recovery keys securely.
- List the exact Wi-Fi, graphics, printer, dock, and specialty devices.
- List every essential app, game, and protected file format.
- Keep the computer connected to power during firmware or disk work.
- Label the installer USB so it is not confused with a backup drive.
Build the live USB step by step
- Choose the distribution.
Use the Ubuntu vs. Mint vs. Fedora comparison if you have not decided. - Download the ISO only from the official project.
Avoid repackaged images, download portals, and unofficial “optimized” versions. - Verify the download.
When the project publishes checksums or signature instructions, follow them before writing the USB. - Write the image with a trusted tool.
Select the ISO and the correct removable drive. The drive will be erased. - Open the one-time boot menu.
Use the computer maker’s documented boot-menu key instead of permanently changing firmware order when possible. - Choose “Try” or the live-session option.
Do not start installation until the hardware checklist passes and your backup is complete.
Live-session hardware checklist
| Test | What to do | Do not ignore |
|---|---|---|
| Networking | Join Wi-Fi, test Ethernet, Bluetooth, and VPN requirements | Missing adapter, unstable connection, or weak resume |
| Graphics | Try native resolution, scaling, external displays, and video playback | Flicker, black screens, tearing, or missing brightness control |
| Audio/video | Test speakers, headphones, microphone, webcam, and conferencing | Wrong input/output, low volume, or absent camera |
| Power | Test sleep, wake, shutdown, battery reading, and lid behavior | Failure to wake, excessive heat, or rapid battery drain |
| Input/accessories | Test keyboard keys, touchpad gestures, mouse, printer, dock, and card reader | Features you use daily that need manual workarounds |
Install only after the test passes
- Update the backup one last time.
Disconnect backup drives before installation so they cannot be selected accidentally. - Understand every disk option.
“Erase disk,” “install alongside,” and manual partitioning have very different consequences. - Prefer the simplest layout that meets your needs.
A separate test computer or drive is easier to recover than a complex dual-boot layout. - Finish updates from built-in tools.
After the first boot, use the distribution’s updater and official software sources before adding third-party scripts. - Keep recovery media and backups.
Do not erase the working installer or Windows recovery media until the new system has been dependable for a while.

Will a live USB erase my computer?
Booting a standard live session does not erase the internal drive. Erasing or repartitioning can happen only if you launch the installer and approve disk changes, so read every storage choice carefully.
How large should a Linux installer USB be?
An 8 GB drive is often enough for one current desktop image, but 16 GB or more gives comfortable room. Confirm the current image size and the writing tool’s instructions before buying or erasing a drive.
Should I disable Secure Boot?
Not automatically. Ubuntu, Linux Mint, and Fedora can support Secure Boot in many configurations. Test first and follow the selected distribution’s current official documentation for the exact hardware.
Can I keep Windows and install Linux?
Yes through dual booting or separate drives, but partition changes carry risk. Back up files, save encryption recovery keys, and create Windows recovery media first.
