Причины ошибки 0x0000008B: MBR CHECKSUM MISMATCH

На официальном сайте, а также на форуме Microsoft указано, что ошибка 0x0000008B чаще всего появляется из-за вирусов. Однако некоторые пользователи делились комментариями, в которых указано, что синий экран смерти MBR_CHECKSUM_MISMATCH на их ПК появился вследствие повреждения загрузочного сектора, а в некоторых случаях – жесткого диска.

Казалось бы, что сложного в решении данной ситуации? Однако существует много видов вирусов и не все могут быть обнаружены. Как правило, для сканирования ПК нужно использовать антивирусы с обновленными вирусными базами, а еще лучше, использовать антивирусный сканер Dr. Web Curelt, записанный на флешку с пометкой «Только чтение» (без записи). Иногда вирусы повреждают файлы защитника еще до того, как он будет запущен. Поэтому активация режима «Только чтение» может помочь решить проблему.

Также при поисках решения проблемы нужно проверить загрузчик MBR, а также просканировать жесткий диск на наличие или отсутствие поврежденных секторов.

Методы решения ошибки 0x0000008B: MBR CHECKSUM MISMATCH

Чтобы решить проблему с синим экраном смерти 0x0000008B: MBR CHECKSUM MISMATCH, стоит создать проверочный защищенный носитель. Для этого стоит воспользоваться следующими рекомендациями:

• Подключаем к ПК флешку. Заходим в Проводник и нажимаем на съемном носителе правой кнопкой мыши. Выбираем «Форматировать».

• Выбираем файловую систему NTFS и кликаем «Начать».

• Подтверждаем выполнение действий.

После форматирования флешки выполняем новые действия.

• Создаем на флешке новую папку и помещаем туда файл антивирусного сканера. Мы будем использовать Dr. Web.
• После того, как вы скопировали на флешку файл, нажимаем на самом диске правой кнопкой мыши и выбираем «Свойства».

• Откроется небольшое окно. Переходим во вкладку «Безопасность» и нажимаем на кнопку «Изменить».

• Появится еще одно окно. Ставим отметки «Разрешить» в пунктах «Чтение и выполнение», «Список содержимого в папках», «Чтение», а также отметку «Запретить» в пункте «Запись».

• Подтверждаем выполнение операции.

ВАЖНО! В случае, если появится окно «Ошибка применения безопасности», то нажимаем «Отмена», «Отмена», «ОК».

• Далее возвращаемся ко вкладке «Безопасность». Нажимаем на кнопку «Дополнительно».

• Откроется небольшое окно. Нажимаем «Изменить разрешение…».

• Двойным кликом открываем пункт «Запись», которому назначен параметр «Запретить».

• Появится окно элемента разрешения. В разделе «Запретить» выставляем все отметки, кроме «Полный доступ», «Траверс папок», «Содержание папки», «Чтение разрешении».

• Теперь переходим к папке с антивирусным сканером. Нажимаем на ней правой кнопкой мыши и выбираем «Свойства».
• Откроется небольшое окно. Переходим во вкладку «Безопасность» и нажимаем на кнопке «Дополнительно». Далее «Изменить разрешение» и в следующем окне нужно убрать галочку «Добавить разрешения, наследуемые от родительских объектов». А в запросе ответить «Удалить».
• Далее нажимаем «Добавить», «Дополнительно», выбираем «Поиск» и двойным кликом нажимаем на параметре «Все». Жмем «ОК».
• В окне «Элемент разрешения для …название вашей папки с антивирусом». Ставим отметки «Удаление», «Смена разрешения», «Смена владельца». Этим параметрам задаем значение «Запрещено».
• Далее вновь нажимаем «Добавить», «Дополнительно…», «Поиск». Двойной клик по кнопке «Все» в результатах поиска. Жмем «ОК», а в окне «Элемент разрешения для …название папки с антивирусом» ставим десять галочек, как на рисунке. Жмем «ОК».

• В окне «Дополнительные параметры безопасности для …название папки с антивирусом» нажимаем «ОК».

ВАЖНО! Если появится окно «Ошибка применения безопасности», то кликаем «Отмена», «Отмена», «ОК».

Флешка создана. Можно запустить проверку системы на вирусы. Рекомендуем выполнить несколько проходов, в том числе и в безопасном режиме.

В случае, если антивирус все же не обнаружил каких-либо вирусов, стоит просканировать жесткий диск на наличие или отсутствие поврежденных секторов. Для этого рекомендуем использовать программы Victoria HDD, MHDD или HDD Scan. Они проанализируют состояние диска. Первая программа позволит заменить бытые сектора здоровыми.

Если софт не обнаружит нарушение целостности секторов, то стоит попробовать восстановить загрузчик MBR. Для этого нужно подключить к ПК установочный диск или флешку с той же версией и разрядностью Windows. В BIOSе выставляем приоритетность загрузки с носителя. Далее, как только появится окно установщика, выбираем «Восстановление системы».

Далее выбираем «Командную строку».

В консоли вводим bootrec /fixmbr. Эта команда перезаписывает MBR Windows 7 на системном разделе жесткого диска. Однако, этого не всегда работает (например, в случае с вирусами в MBR), а потому следом за этой командой обычно используют еще одну, которая записывает новый загрузочный сектор Windows 7 на системный раздел: bootrec /fixboot.

В случае, если исправить неполадку вышеуказанными способами не удалось, стоит выполнить переустановку Windows с форматированием разделов.

In this blog post, we find out the different reasons that show the Error 0x000000B8 along with its probable solutions. It may also show ATTEMPTED_SWITCH_FROM_DPC which usually occurs when a program that is incompatible with the system is used. This error may also be abbreviated as STOP 0xB8 but the full STOP code will always be what’s displayed on the blue screen message.

Most of the time, the ATTEMPTED_SWITCH_FROM_DPC error is caused by viruses or issues with antivirus software. Nonetheless, like almost every STOP code, there’s always a possibility that the source reason is hardware-related or has something to do with a device driver. In this state, your PC may stop working some basic and vital functions with automatic Restarting of Windows which causes the unsaved work or data will be immediately lost. However, if Windows is able to start after the BSOD error 0x000000B8, you may be prompted with:

Windows has recovered from an unexpected shutdown message that shows:

Problem Event Name: BlueScreen
BCCode: B8

Note – The most simple and basic way to resolve STOP code 0x000000B8 is to perform the manual update procedure which is to revert to the last successful boot. In order to do this, you must restart the device and wait for it to reach the BIOS messages. Generally, you will receive this error while starting a new program or installing updates.
