Learn how to flash USB drives and SD cards with confidence. FlashLab turns a task that often feels risky into a clear, step-by-step skill, with short lessons, hands-on simulations, and quizzes that check your understanding.

What you’ll learn
12 modules, organized in 4 phases:

• Phase 1, Foundations: what flashing is, disk images and bootable media, installing Etcher on Windows, macOS, or Linux, and safe preparation with backups and checksums.
• Phase 2, Core skills: your first flash from a file, flashing from a URL, cloning a drive, and reading validation results.
• Phase 3, Real-world projects: preparing a Raspberry Pi microSD card, creating a bootable Linux live USB, and knowing when another tool is the better choice.
• Phase 4, Troubleshooting and mastery: fixing common errors, restoring a flashed drive to normal storage, and a final assessment.

Practice without risk
Every module includes interactive simulations that never touch your real drives:
• Copy or flash: watch, block by block, why copying an ISO file isn’t the same as flashing it.
• A complete flash simulator with target warnings, permission prompts, progress, and validation.
• Drive cloning, a validation lab, and result-reading exercises.
• A boot menu simulator based on common laptop brands.
• A guided diskpart terminal for restoring drives on Windows.
• Checksum comparisons, file sorting, and step-ordering challenges.

Features
• Theory and practice in every module
• Quizzes with clear explanations for every answer
• Progress tracking for each phase
• A final assessment with a certificate of completion, for personal motivation (not an accredited qualification)
• Light and dark themes
• Lessons that work offline
• Clear English written for beginners

Who it’s for
Beginners, students, makers, and anyone who wants to try Linux, set up a Raspberry Pi, or create bootable media without fear of making a costly mistake.

Good to know
Software menus, features, and supported formats can change between versions. Always check the official documentation for the version you use. FlashLab is educational content only, and you remain responsible for the drives and data on your own devices.
