BCD stands for Boot Configuration Data. It contains Boot Configuration Parameters on how to start the Windows operating system. When BCD gets corrupted or goes missing, you will experience boot issues on your system. Such types of boot issues can be fixed by rebuilding the BCD file in normal circumstances. However, if the rebuild BCD command fails, you will not be able to boot into Windows. In this article, we will talk about the error message  Total identified Windows installations 0 which you may see after a failed Windows boot.

Some users experienced boot issues on their systems after frequent crashes or after upgrading their systems. To fix boot issues, when they attempted to repair BCD in WinRE, the command failed to do so and displayed the following result:

Scanning all disks for Windows installations.

Please wait, since this may take a while…

Successfully scanned Windows installations.
Total identified Windows installations: 0
The operation completed successfully.

After starting the computer, they may again receive the same error message, when rebuilding the BCD. If you are also stuck with the same error, use the following solutions and see which one works for you.

1. Mark the Windows partition as active
2. Remove the hidden, system, and read-only attributes from the BCD file, and rebuild BCD again
3. Copy the Registry files from the RegBack folder
4. Seek professional help

Let’s start.

1] Mark the Windows partition as active

One solution to fix this issue is to mark the Windows installation partition as active. This fix has worked for many users. You can also try this.

Launch the Command prompt in Windows Recovery Environment.

1. Type Diskpart and hit Enter.
2. Type list volume and hit Enter.
3. Type select volume #. In this command, replace # with the volume on which Windows OS is installed.
4. Type active and hit Enter.
5. Type exit to leave Diskpart.
6. Now, see if you can rebuild BCD and restart your computer.

2] Remove the hidden, system, and read-only attributes from the BCD file, and rebuild BCD again

If the above fix did not help you, you have to remove the hidden, system, and read-only attributes from the BCD file and then rebuild the BCD file again. Go through the following instructions.

Boot from Windows Installation Media and open Command Prompt in Windows Recovery Environment.

Type bootrec /rebuildbcd and hit Enter. You will see the following message:

Successfully scanned Windows installations.
Total identified Windows installations: 0
The operation completed successfully.

Now, type the following command and hit Enter.

bcdedit /export c:\bcdbackup

Now, type the following command to remove the hidden, system, and read-only attributes from the BCD file.

attrib c:\boot\bcd -h -r -s

Now, you have to rename the BCD store. To do so, execute the following command and hit Enter.

ren c:\boot\bcd bcd.old

Now, type the following command to rebuild BCD.

bootrec /rebuildbcd

This time, you should get the following output:

Successfully scanned Windows installations.
Total identified Windows installations: 1

Type Y and hit Enter. Exit the Command Prompt and restart your computer. The issue should get fixed.

If after removing the hidden, system, and read-only attributes from the BCD file, Command Prompt shows you the following error message, your hard disk partition table is GPT and not MBR, or you have selected the wrong drive for the boot partition.

Path not found – C:\boot

In this case, you have to follow a different approach. You can also check your hard disk partition style. For this, open Command Prompt and type the following commands.

diskpart
list disk

Press Enter after typing each of the above commands. The Command Prompt will show you all the hard disks installed on your system. If you see the asterisk under the GPT column, your hard disk has the GPT partition table, otherwise it has the MBR partition table.

Because you have a GPT hard disk, you have to follow the procedure explained below.

Launch the Command Prompt in Windows Recovery Environment and type:

Diskpart

list volume

Press Enter after typing each of the above commands. Usually, the EFI partitions do not have a drive letter. Check this. The EFI partition is in FAT32 format and of size about 200 MB. If the EFI partition does not have a drive letter, you have to assign a drive letter to it.

Type the following command to select the EFI partition.

select volume #

In the above command, replace # with the correct volume number. Now, type:

assign letter=z:

You can assign any available drive letter to the EFI partition. Type list volume again to check if the letter z is assigned to the EFI partition or not. Once done, type exit and press Enter to exit Diskpart.

Now, check if the volume to which you have assigned the letter z is the correct EFI partition or not. List all files by executing the following command:

DIR  /A /B /S Z:

In the above command, Z is the drive letter. The result should show Z:\EFI\Microsoft\Boot\BCD in any of the lines. If yes, you have assigned the letter to the correct EFI partition.

Do not close the Command Prompt window. Now, open another Command Prompt window by pressing the Shift + F12 keys. Or, you can continue executing the commands in the same Command Prompt window. But launching another Command Prompt window will make things simpler for you.

Type bootrec /rebuildbcd and hit Enter. The result will show you the same message that we are discussing in this article. Now, type the following command to create a backup of the existing BCD.

bcdedit /export c:\bcdbackup

Now, delete the hidden, system, and read-only attributes from the BCD file by using the following command:

attrib <correct file path> -h -r -s

Previously, in the case of the MBR disk, we used the c:\boot\bcd as the file path in the above command. But in this case, the file path will be different. Go to the previous Command Prompt window and copy the path Z:\EFI\Microsoft\Boot\BCD. In your case, the drive letter may be different. Now, the complete command is:

attrib Z:\EFI\Microsoft\Boot\BCD -h -r -s

Now, rename the BCD files by using the following command:

ren Z:\EFI\Microsoft\Boot\BCD BCD.old

Now, rebuild BCD using the command written below:

bootrec /rebuildbcd

You should get the following output:

Successfully scanned Windows installations.
Total identified Windows installations: 1

Type Y and hit Enter. Close the Command Prompt by typing exit and hitting Enter. Now, click Continue to restart your computer.

3] Copy the Registry files from the RegBack folder

This fix is for users with Windows OS earlier than Windows 10 version 1803 and assuming you can access the folder. On Windows operating systems earlier than Windows 10 version 1803, the Registry backup was stored in the RegBack folder. This folder is located at the following location:

C:\Windows\System32\config

The registry backup is no longer saved in the RegBack in Windows 10, version 1803 and later. If you open the RegBack folder, you will find it empty. Or if any files are located inside this folder, they have a size of 0 KB. This change is by design. Microsoft implemented this change to Windows 10, version 1803 and later to help users reduce the overall disk footprint size of Windows.

Therefore, if you have Windows 10 version 1803 or later, this fix will not work for you. Hence, you have to use System Restore to fix the issues occurring due to corrupted Registry Hive(s). Other users can try this fix. Before applying this fix, you have to rename the registry files in the Config folder. After doing that, you can copy the registry backup files from the RegBack folder to the Config folder. Hence, if the problem was occurring due to Registry corruption, this will fix the issue.

Before executing any command, it is better to check if the RegBack folder contains any backup files or not. To do so, open the Command Prompt in Windows Recovery Environment and type Notepad. Hit Enter after that. When Notepad opens up, go to File > Open or press the Ctrl + O keys. This will open the File Explorer. Now, go to the above-mentioned location and open the RegBack folder. See if it contains any Registry backup files or not. If yes, do not forget to check their sizes. If the files show 0 KB, they do not contain any backup data. Hence, in this case, you cannot apply this fix.

Now, first, change the directory by typing the flowing commands. Press Enter after typing each of the following commands. Although the OS resides in the C directory, this directory may change on some computers. Hence, use the correct drive letter.

C:
cd Windows
cd System32
cd Config

Now, the directory in the Command Prompt should show the following path:

C:\Windows\System32\config>

After changing the directory, rename the following files:

• DEFAULT
• SAM
• SECURITY
• SOFTWARE
• SYSTEM

To rename the above files, use the following commands. Press Enter after typing each of the following commands.

ren DEFAULT DEFAULT.old
ren SAM SAM.old
ren SECURITY SECURITY.old
ren SOFTWARE SOFTWARE.old
ren SYSTEM SYSTEM.old

Now, type the following command to enter the RegBack directory.

cd RegBack

Make sure that the complete directory in the Command Prompt is shown the same as written below:

C:\Windows\System32\config\RegBack>

Use the copy command to copy the files one by one. Press Enter after typing each of the following commands:

copy DEFAULT "C:\Windows\System32\config"
copy SAM "C:\Windows\System32\config"
copy SECURITY "C:\Windows\System32\config"
copy SOFTWARE "C:\Windows\System32\config"
copy SYSTEM "C:\Windows\System32\config"

Exit the Command Prompt and click Continue to restart your computer. You should be able to boot into Windows without any problem.

Худший вид ошибок Windows — это тот, который нелегко решить из-за того, что вы еще не загрузились на свой компьютер. Когда вы уже загрузились в свою операционную систему Windows и можете использовать различные средства устранения неполадок и инструменты, решить проблему неизмеримо проще.

Именно поэтому эту ошибку так сложно исправить. Он появляется при запуске и ничего не работает. Что бы вы ни пытались, появляется сообщение «Всего идентифицированных установок Windows: 0», оставляя вас беспомощным. Следуйте инструкциям в статье ниже, чтобы попытаться решить проблему.

Подготовка:

Чтобы выполнить любое из действий по устранению неполадок, описанных в этой статье, вам необходимо подготовить установочный DVD-диск Windows или USB-накопитель, который вы будете использовать для устранения всех неполадок. Для более старых версий Windows (старше Windows 10) вам потребуется использовать оригинальный диск, который вы получили с операционной системой. Однако для Windows 10 это легко создать.

1. Загрузите Media Creation Tool с официального сайта Microsoft. Дважды щелкните загруженный файл с именем MediaCreationTool.exe, чтобы запустить мастер. Коснитесь Принять.
2. Выберите «Создать установочный носитель (USB-накопитель, DVD или файл ISO) для другого ПК» на начальном экране.

1. Язык, архитектура и выпуск загрузочного диска будут выбраны в зависимости от конфигурации вашего компьютера, но вы должны снять флажок Использовать рекомендуемые параметры для этого ПК, чтобы выбрать правильные настройки для сломанного ПК (вероятно, вы создаете этот на другом ПК).
2. Нажмите «Далее» и выберите вариант USB-накопителя или DVD, когда будет предложено выбрать между USB или DVD, в зависимости от того, какое устройство вы хотите использовать.

1. Щелкните Далее и выберите диск из списка, в котором отображаются устройства хранения, подключенные к вашему компьютеру.
2. Нажмите Далее, и Media Creation Tool продолжит загрузку файлов, необходимых для установки, и создаст установочный носитель.

Решение 1. Восстановление реестра

Восстановление реестра — один из единственно рациональных шагов, которые вы можете предпринять для решения проблемы. Вы все равно должны знать, что проблема может быть вызвана различными обстоятельствами. Если один из ваших компонентов, например, диск, на котором расположена ваша операционная система, поврежден, вы ничего не можете сделать, кроме как заменить его.

Однако, если проблема действительно связана с поврежденными записями реестра, вы можете исправить ее, выполнив следующие действия:

1. Вставьте диск восстановления, которым вы владеете или который вы создали для своей операционной системы, и запустите компьютер. Следующие шаги различаются в зависимости от операционной системы, поэтому выполняйте их соответственно:

WINDOWS XP, VISTA, 7: Окна установки Windows должны открыться с предложением ввести язык вместе с настройками времени и даты. Введите их и после продолжения выберите «Восстановить компьютер» в нижней части экрана. При появлении запроса «Использовать инструменты восстановления» или «Восстановить компьютер» установите первый переключатель и нажмите кнопку «Далее». Выберите «Командная строка», когда появится экран «Выбрать средство восстановления».

ОКНА 8, 8.1, 10: Вы увидите экран «Выберите раскладку клавиатуры», поэтому выберите ту, которую хотите использовать. Появится экран выбора варианта, поэтому нажмите Устранение неполадок >> Дополнительные параметры >> Командная строка.

1. Перейдите в следующую папку в командной строке «C: Windows System32 config», используя команду, показанную ниже. Обязательно нажимайте Enter после каждого.

cd windows
cd system32
cd config

Выполните следующие команды, чтобы заменить папки DEFAULT, SAM, SECURITY, SOFTWARE и SYSTEM:

del c: windows system32 config sam del c: windows system32 config security del c: windows system32 config software del c: windows system32 config default del c: windows system32 config system copy c: windows tmp software c: windows system32 config software copy c: windows tmp system c: windows system32 config system copy c: windows tmp sam c: windows system32 config sam copy c: windows tmp security c: windows system32 config security copy c: windows tmp default c: windows system32 config default

1. Проверьте, решена ли проблема после перезагрузки компьютера и попытки загрузки без DVD восстановления.

Решение 2. Восстановление загрузки

Существует полезная встроенная функция под названием Boot Recovery, к которой можно легко получить доступ через командную строку. Как следует из названия, этот инструмент может помочь вам легко загрузиться на ваш компьютер и помочь вам исправить различные проблемы, которые могли возникнуть в процессе загрузки.

1. Если вы не можете получить доступ к командной строке в противном случае, выполните тот же набор шагов, что и выше, чтобы получить доступ к командной строке с диска восстановления.
2. Введите следующую команду и убедитесь, что вы нажали Enter после правильного ввода:

bootrec / rebuildbcd

1. Вы должны увидеть сообщение:

Сканирование всех дисков для установки Windows.
Подождите, это может занять некоторое время…
Установки Windows успешно просканированы.
Всего идентифицированных установок Windows: 0
Операция завершилась успешно.

1. Поскольку у вас, очевидно, установлена ​​Windows, вам нужно будет «удалить» и заново собрать ее из списка, используя следующие команды:

bcdedit / export c: bcdbackup attrib c: boot bcd -h -r -s

1. Первая команда создала резервную копию предыдущего хранилища BCD, а вторая удалила определенные атрибуты, которые ограничивали действия, которые вы могли предпринять с ним. Теперь вы можете удалить или переименовать его и восстановить заново с помощью этой команды:

ren c: boot bcd bcd.old

1. Теперь вы можете повторить ту же команду, которую мы пробовали в начале, когда мы получили сообщение об установке 0 Windows:

bootrec / rebuildbcd

1. Появится следующее сообщение:

Подождите, это может занять некоторое время…

Установки Windows успешно просканированы.
Всего идентифицированных установок Windows: 1
[1] D: Windows
Добавить установку в список загрузки? да/ Нет/Все:

1. Нажмите Y, и вы должны увидеть сообщение «Операция успешно завершена», означающее, что восстановление BCD завершено. Перезагрузите компьютер и проверьте, можете ли вы нормально загрузиться.
