Note! Installing FydeOS on the hard drive will erase all data on the hard drive. We cannot be responsible for potential data loss and problems that may occur in the installation or provide timely technical support. Please think twice!

In the recent releases of FydeOS, you will be given the option to install FydeOS during the first boot wizard (OOBE). In addition, in the latest version of FydeOS for PC, we provide a graphical installation app, "Installer", that you can install and use in the "FydeOS Web Store". If the app does not work, try the following tutorial.

#0. Boot FydeOS for PC via USB

Please refer to to make a FydeOS for PC that can be booted and successfully boot into the graphical interface of FydeOS on the target PC.

#1. Enter the terminal

After the FydeOS for PC graphical interface appears, please press the Ctrl + Alt + F2 key on the keyboard (on some computers, such as Apple Mac, you need to press Fn + Ctrl + Alt + F2, then the system will automatically switch to TTY command line mode. If necessary, press Ctrl + Alt + F1 (or Fn + Ctrl + Alt + F1) Return to the graphical interface mode.

#2. Log in

FydeOS will prompt you to enter your username and password in command line mode. In FydeOS for PC, the default user name is chronos, the user has no password by default, and after entering the command line, it will enter the developer mode.

#3. Confirm the target disk

Enter the command lsblk to get the list of currently loaded physical disks. Typically, the physical hard disk in your PC will be displayed in the form of sdX. According to the prompted disk space size and the number of partitions, please determine the physical disk letter of FydeOS, such as sda. The following command will take sda as an example.

#4. Run the installation script

Input the command:

sudo /usr/sbin/chromeos-install --dst /dev/sda

The installation script will finally confirm whether you want to continue and prompt that the target disk will be emptied if you continue. If you are sure, please enter Y and press Enter to confirm.

#5. Wait for the script to execute

Make yourself a cuppa and watch an episode of Star Trek.

#6. After running the script

If prompted, please remove the USB drive, restart the computer, and fingers cross for all of the above. Good luck.
