+ | * Connect the USB cable quickly and fully. The USB connector is designed so that when you connect the cable, the power contacts are connected first, then the data contacts. In this case, a situation may arise when, when the power is turned on, the boot process has already begun, and the USB data lines have not yet been connected; | ||
+ | * Use a USB 2.0 cable instead of a USB 3.0 cable. | ||

+ | * If the controller is connected to a network with access to the Internet, the time zone, language for the system and keyboard layout will be automatically determined; | ||
+ | * Next, you will be prompted to register a new user in the system and set a password for him (it is recommended to do this). User data entry can be skipped by pressing the Enter key when prompted for the user's full name. | ||
