You can download the balenaEtcher installation package for Windows, macOS or Linux from .

In addition, you need to prepare a USB disk above 8G and insert it into your computer. Please note that all data on this disk will be erased, so please ensure data backup is done in advance.

Please download the image file of the corresponding version of FydeOS for PC on our download page. After the download is complete, you will see a .xz file. No need to unzip and rename; open the image file directly with balenaEtcher; next, select the USB disk that will be used to flash FydeOS; finally, you only need to click the "Flash!" button, and balenaEtcher will handle the rest for you!

After flashing, you can remove the USB card and insert it into your PC, restart the computer, and configure your PC to boot through the USB drive to enjoy FydeOS.
