However, sometimes you may set incorrect BIOS order, in which situation the computer boot from another partition or another disk which contains no system. Thus, it says BOOTMGR is missing and cannot boot from Windows. This problem might occur when you have inserted a removable disk or a second hard disk drive to your computer.

6. Чтобы подтвердить действие, кликаем «Исправить и перезапустить»;
7. Поздравляем, проблема решена.

Если же изменений не произошло, пробуем следующий вариант:

1. Повторяем загрузку с диска или USB-флешки;
2. Снова выберите пункт «Восстановление системы»;
3. Появится перечень доступных OS, укажите свою и кликните «Далее»;
4. В следующем окне выбираем пункт «Восстановление запуска операционной системы»;
5. Ожидаем завершения процедуры сканирования/выполнения поставленной задачи, затем проверяем корректную работу компьютера.

Устранение ошибки BOOTMGR is missing Press Ctrl + Alt + Del to restart с помощью командной строки

В этом случае нам так же потребуется дистрибутив с Windows 8, 10 или 7.

1. Как и в предыдущем методе, нужно загрузиться с диска с образом системы;
2. Вы можете пропустить пункт с вводом ключа активации, достаточно указать оптимальный язык;
3. Необходимо выбрать раздел «Восстановление системы», расположенный в нижней части экрана;
4. Указываем нужную OS, в которой следует восстанавливать загрузчик, кликаем «Далее»;
5. Следующим шагом является пункт «Командная строка»;
6. Перед вами откроется интерфейс консоли;
7. Вводим команду bootrec.exe /FixMbr и нажимаем Enter;
8. Дальше набираем bootrec.exe /FixBoot;
9. Остаётся перезагрузить компьютер и проверить, работает ли функция запуска системы, не появляется ли ошибка.

Не получилось? Тогда снова войдите в интерпретатор и введите bcdboot.exe c:windows (в данном случае c:windows — путь к системному разделу, если у вас диск D, укажите его вместо C). Команда восстановления загрузки системы должна исправить сложившуюся ситуацию и устранить повреждения Windows.

Второй способ восстановления загрузчика операционной системы через командный интерпретатор

В ходе инсталляции Виндоус, создаётся специальный скрытый раздел размером от 100 до 300 Мб. Именно в нём содержатся несколько важных системных файлов, среди которых есть менеджер загрузки Windows (мини-программа, отвечающая за корректный запуск). Если файл bootmgr повреждён либо отсутствует, на вашем компьютере возникнут проблемы со штатным загрузчиком, что обязательно приведёт к наличию рассматриваемого нами сбоя. Задача юзера – скопировать файл с загрузочного носителя.

1. Для начала вызываем командную строку (аналогично третьему пункту нашей статьи);
2. Вводим в консоль команду diskpart, кликаем Enter, затем набираем list volume и подтверждаем действие;
3. Теперь важно найти нужный диск с резервными данными, ему может быть присвоена буква F, D, C, E и так далее (в нашем случае, это «C»);
4. Сразу же обращаем внимание на букву диска CD/DVD-ROM (в нашем примере это «F»);
5. Выходим из меню diskpart командой Exit;
6. Переходим на букву CD/DVD-ROM, посредством ввода F:
7. Копируем файл bootmgr на раздел размером 100-300Мб, для этого прописываем следующую команду copy bootmgr C: и жмём Энтер (как показано на скриншоте);
8. После того, как увидите сообщение о том, что файл скопирован, выходите из консоли, набрав Exit;
9. Перезагружаете ПК или ноутбук и смотрите, получилось ли устранить проблему методом копирования.

Если скрытый раздел Windows не отображается, просто копируем bootmgr на все диски с данными (copy bootmgr D:, copy bootmgr E: и так далее). Перезагружаем устройство и проверяем его работоспособность.

Если ни один из способов решения неполадки не помогает, снова откройте командную строку и введите bootsect /nt60 All и перезагрузите компьютер.

Не помогло? Значит ваш диск или раздел не активный!

Делаем диск активным в командном интерпретаторе:

1. Вводим diskpart, далее list disk;
2. В открывшемся перечне пронумерованных HDD, выбираем физический диск, на котором установлена операционная система Windows, к примеру: select disk 0 или 1;
3. Пишем list partition и ищем тот самый раздел на 100 — 300 Мб. Если же его нет, выбираем первый или второй раздел, в зависимости от того, на какой именно была установлена ОС;
4. После этого вводим команду select partition 1 или 2 (номер выбранного диска);
5. Активируем раздел с помощью команды active;
6. Если всё сделано правильно, появится уведомление о том, что раздел помечен активным;
7. Перезагружаем ПК/лэптоп, чёрный экран с ошибкой должен исчезнуть.

Исправляем ошибки при помощи специализированного софта

Существуют и специальные приложения, позволяющие избавиться от рассматриваемой нами неполадки. Как и в описанных выше методах, нам понадобится установочная флешка/диск, но не с дистрибутивом OS, а c диском LiveCD (Hiren’s BootCD, RBCD и т.д). В этих образах хранятся интересующие нас программки.

Исправить проблему и восстановить конфигурации загрузки можно с помощью утилиты MbrFix, Acronis Disk Director, Bootice, Ultimate MBRGui или Acronis Recovery Expert. ПО поддерживает любые версии Windows от XP и выше. Например, в МбрФикс достаточно ввести команду MbrFix.exe /drive 0 fixmbr /win7 (или win8, win10), а затем подтвердить пользовательские изменения.

К сожалению, не все программы обладают интуитивно понятным интерфейсом на русском языке и удобным подсказчиком для новичков. Будьте внимательны! Не имея определённых знаний и опыта, можно навредить компьютеру, что приведёт к неизбежному обращению в сервсиный центр и последующему вызову мастера для ремонта компьютера.
