Process
Straighforward and safe:
💿 If the USB is old, copy a new ISO file into it.
🔌 With the USB connected, reboot the computer. If no menu appears, reboot again while pressing quickly and repeatedly the boot key. Select the USB name.
📥 Just follow the steps on the screen to reach a desktop. There run the app “Install System”.
Securing
(Only if the user is able to unlock booting by themselves)
