Enable boot logging windows 10 что это

Компания Microsoft в ходе обновления своих операционных систем часто меняет способы активации функций, к которым все пользователи привыкли. Зачастую даже опытным пользователям Windows сложно разобраться, где в Windows 10 включить лог загрузки операционной системы, чтобы после его можно было посмотреть и проанализировать. В рамках данной статьи рассмотрим, как в Windows 10 включить лог загрузки.

Зачем нужен лог загрузки

Многие пользователи вовсе не знают, что такое лог (или журнал) загрузки, и зачем он нужен. Если не вдаваться в детали, то лог загрузки — это простой текстовый файл, который содержит в себе информацию для анализа процесса старта компьютера и операционной системы.

Чаще всего лог загрузки необходим системным администраторам, чтобы понять, какие проблемы препятствуют загрузке операционной системы, вызывают те или иные ошибки при запуске программ или в процессе работы Windows. В логе загрузки отображается полный список загружаемых при старте компьютера драйверов и библиотек.

Где находится лог загрузки в Windows 10

В операционной системе Windows 10 лог загрузки располагается на системном диске в папке Windows. Файл называется ntbtlog.txt.

Обратите внимание: Как можно видеть, это обычный текстовый файл. Его можно открыть при помощи стандартного приложения “Блокнот” или других сторонних программ, которые позволяют работать с txt файлами.

Как включить лог загрузки в Windows 10

Чтобы текстовый файл ntbtlog.txt появился в папке Windows, нужно его сгенерировать. По умолчанию в Windows 10 отключен процесс создания данного файла при загрузке компьютера.

Включить создание файла журнала загрузки можно двумя способами:

  • Через настройки конфигурации системы. Чтобы это сделать, необходимо запустить утилиту “Конфигурация системы”. Для запуска этой утилиты нажмите на клавиатуре сочетание Win+R, чтобы открылось окошко “Выполнить”. В нем пропишите команду для запуска утилиты — msconfig. Откроется окно “Конфигурация систему”, где нужно сверху переключиться на вкладку “Загрузка” и далее в разделе “Параметры загрузки” установить галочку у пункта “Журнал загрузки”. После этого нажмите “Применить” и “ОК”, чтобы изменения вступили в силу. Появится сообщение с предложением перезагрузить компьютер. Нажмите “Перезагрузка”, чтобы сразу выполнить создание лога загрузки в папке Windows. В таком случае компьютер перезагрузится. Если нажать “Выход без перезагрузки”, тогда лог загрузки будет создан после следующей перезагрузки компьютера.
  • Через командную строку. Второй способ предлагает использование командной строки. Чтобы создать через нее лог загрузки, запустите командную строку от имени администратора и используйте в ней команду bcdedit. После этой команды в окне консоли командной строки появятся сведения обо всех операционных системах, установленных на компьютере, и их загрузочных записях. Если на компьютере установлена одна операционная система Windows 10 (как на примере на скриншоте), тогда будет отображаться два списка элементов — диспетчер загрузки и загрузка Windows. Необходимо обратиться к загрузке Windows, у которой имеется идентификатор current. Пропишите в командной строке следующее: 
    bcdedit /set {current} bootlog Yes

    Важно: Если у вас идентификатор отличный от {current}, необходимо заменить на него часть команды, используемой выше.
    После выполнения этой команды необходимо перезагрузить компьютер, чтобы лог загрузки был создан в папке Windows.

Как читать лог загрузки Windows 10

Несмотря на то что лог загрузки — это текстовый документ исключительно для системных администраторов, что-то полезное из него может вынести и обычный пользователь.

В журнале загрузки указывается перед каждым из компонентов — был он исполнен или нет:

  • BOOTLOG_LOADED — означает, что драйвер был загружен без ошибок.
  • BOOTLOG_NOT_LOADED — указывает, что во время загрузки операционной системы старт данного драйвера был пропущен.

На основании этой информации можно сделать выводы о том, с какими драйверами на компьютере могут быть проблемы.
