Hi, I'm new to Linux and want to completely replace Windows with Linux Mint rather than dual-booting. I'm nervous about accidentally wiping important data because my C: drive contains projects, coding-agent files, and other things I need to keep. This is my main laptop, so I can't afford to lose anything or have it unusable for long. What should I back up, how can I verify that the backup is complete, and what should I check before doing a clean installation?

Create a bootable Linux Mint USB and try the live environment before installing. Test the Wi-Fi, camera, audio, graphics, touchpad, external displays, and anything else you use regularly. The live session won’t replace Windows, so it’s a good way to find hardware problems early. You can also test important cross-platform applications while Windows is still available.
A cautious approach is to move your data to a separate drive, then perform the clean installation and copy the files back afterward. An even safer option is installing Linux on a new SSD while leaving the original Windows drive untouched. That gives you a way to return to the old setup if something goes wrong. Also check whether the software you depend on has Linux versions or suitable alternatives before wiping Windows.
You don’t necessarily have to jump straight to a full wipe. You could first boot Mint from USB, then try dual-booting or installing it in unused space while keeping Windows available. That lets you gradually move your workflow over and discover whether any specialized programs or file formats cause trouble. Linux usually has alternatives, but they may work differently or require converting files, especially with specialized 3D design software. Once everything you need works and your backups are verified, you can remove Windows later.
The main idea is to plan the transition instead of assuming every Windows application will work exactly the same way. Identify what each program does, find a Linux replacement if necessary, and test it before deleting the old system.
Before changing anything, make a backup of every important file to an external drive. Don’t just copy a few obvious folders—check your development directories, documents, downloads, project files, game saves, screenshots, configuration files, and anything stored inside application-specific folders. Open some files from the backup afterward to confirm that it actually works.
I’m worried because this is my everyday laptop and I can’t risk losing anything. I’ll need to make sure the backup and replacement software are both tested first.
