About “The drive where Windows is installed is locked”
The following information on this error has been compiled by NeoSmart Technologies, based on the information gathered and reported by our global network of engineers, developers, and technicians or partner organizations.
Description and Symptoms
The error messages, alerts, warnings, and symptoms below are tied to this error.
Symptom 1: “The drive where Windows is installed is locked” error screen on startup
The screen below is displayed when you attempt to start your PC. Unlike most errors, this error screen isn’t identified by an error code like the “Your PC needs to be repaired” error:
Refresh your PC The drive where Windows is installed is locked. Unlock the drive and try again. Cancel
Causes of this Error
This error has been known to occur as a result of one of the following causes:
Cause 1: Bitlocker boot agent disabled
The root cause of this issue is due to the usage of Windows Bitlocker encryption. Bitlocker is a whole-disk encryption used to secure user data, but requires that the Bitlocker boot agent be installed. At boot time, this boot agent is used to unlock the Windows drive before attempting to load Windows 7, Windows 8, or Windows 10. If this agent is disabled or overwritten, either on purpose, by accident, or due to 3rd party interference such as 3rd party bootloaders or malware infecting the boot process, this error message can appear.
Cause 2: The TPM has been cleared or reset
BitLocker can optionally use a hardware encryption chip found on most modern PCs and laptops known as the TPM (Trusted Platform Module) to manage the secret keys used for the encryption of data. If this TPM is cleared or lost, either due to the user clearing the TPM manually in the BIOS/firmware setup or due to a TPM firmware upgrade as part of the system firmware/BIOS upgrade process, the keys the TPM contains may be cleared and the system will fail to boot.
Cause 3: BCD file is damaged
The BCD(Boot Configuration Data) file that contains boot configuration parameters for Windows system, is a very important part of booting process. If that file becomes damaged, then the boot process is halted.

В попытках получить какую-нибудь информацию об этой ситуации автор статьи натыкался на скупые и просто копирующие друг друга сообщения с компьютерных форумов. Более или менее правдивое объяснение удалось найти на сайте Microsoft (https://support.microsoft.com/ru-ru/kb/2826045/en-us), правда, на английском языке. Ее автор объясняет появление сообщения «диск на котором установлена система windows заблокирован» следующими действиями пользователя:
- Проводился апгрейд с Windows 7 на Windows 8;
- Была включена технология Intel Smart Response Technology (SRT) для оптимизации производительности компьютера при переходе с обычного винчестера на SSD-диск;
- Пользователь пытался провести восстановление Windows 8 с помощью встроенных средств WinRE «Обновить компьютер» («Refresh your PC») или «Сбросить ПК» («Reset your PC»).
В таких случаях возможно появления сообщения о том, что диск с установленной на нем операционной системой заблокирован. В нерусифицированных ОС это сообщение имеет вид «The drive where Windows is installed is locked. Unlock the drive and try again.»
Причины и решения проблемы
Техподдержка Microsoft говорит, что одной из причин такого сообщения является отсутствие драйвера Intel Rapid Storage Technology (Intel RST), необходимого для технологии Intel Smart Response. Без него эта технология работать не будет, так как она существенно опирается на его использование. В этом случае техподдержка дает совет при возможности загрузить Windows 8 обратиться к производителю ПК и получить инструкции по отключению этой технологии.
Если же возможности войти в начальный экран загрузки нет, то следует:
Из других сообщений на форумах можно отметить, что причина заключается в обновлении драйвера контроллера винчестера, у которого нет цифровой подписи или он не проходит проверку в UEFI-Bios. При этом функция UEFI security Boot может заблокировать его запуск на аппаратном уровне и не дать загрузиться операционной системе. Этот вопрос решается отключением данной функции в Bios.
Есть также сообщения о том, что данное явление возникает после очередного обновления Windows 8. А сделать откат невозможно из-за отсутствия загрузки операционной системы. Есть также советы использовать команду bootrec /fixboot – некоторые добились этим решения проблемы.
Есть также масса других предложений по исправлению данной проблемы, например, на многих ноутбуках есть возможность выполнить восстановление с встроенного раздела Recovery, но положительных ответов на эту рекомендацию нет.
Эта тема – еще одно свидетельство «сырости» Windows 8, которая заставляет разработчиков кивать на производителей, а производителей – на разработчиков.

In most cases, you can do refresh successfully, but sometimes you may receive the following error message: «The drive where Windows is installed is locked. Unlock the drive and try again.«
Are you troubled by such an issue? Why is the hard drive locked?
Possible Causes for «Hard Drive Locked» Error
It is difficult to say what is the exact culprit for this error, so here we just list 4 possible causes:
- mbr(master boot record) is damaged.
- Windows system files are corrupted or damaged.
- BCD (boot configuration data) is damaged. (Note: here, I guess you might be interested in this post: 4 Ways to Fix Boot Configuration Data File Is Missing.)

After knowing causes, you may ask: Windows drive is locked how to unlock Windows 10/8/8.1. Next, let’s see how to unlock a hard drive to fix this error.
6 Solutions — The Drive Where Windows Is Installed Is Locked
Method One: Rebuild MBR with MiniTool Partition Wizard Bootable CD
MBR (master boot record) is a special type of boot sector at the very beginning of partitioned computer mass storage devices. It contains a small amount of executable code called the master boot code, the disk signature, and the partition table for the disk.
And the master boot code scans the partition table for the active partition, finds the starting sector of the active partition, loads a copy of the boot sector from the active partition into memory, and transfers control to the executable code in the boot sector.
Once the master boot code is damaged or corrupted, you are very likely to receive «The drive where Windows is installed is locked» error message when booting or refreshing computer. So you can try rebuilding MBR to see whether this can fix the Windows locked hard drive error.
Now, you might be wondering: How to rebuild MBR effectively to unlock drive Windows 10/8/8.1?
Here, MiniTool Partition Wizard, a professional partition magic developed by a famous software development company based in Canada, is recommended here. Since Windows cannot boot because of hard drive locked error, you can click the Bootable Media feature to get MiniTool Partition Wizard Bootable Edition.
Tip: The free edition of MiniTool Partition Wizard doesn’t provide Bootable Media Builder since this feature is only included in paid editions. Here, you can get MiniTool Partition Wizard Pro Edition from the button below to rebuild MBR to unlock hard drive.

- If the target disk is larger than 2TB, you can check the Use GUID Partition Table for the target disk, because it supports disks larger than 2TB while MBR supports the maximum disk size of 2TB.
Step 4: Read the popup note carefully, and then click the Finish button to continue.
Step 5: Click the Apply button in the top left corner to apply all pending operations.
After rebuilding MBR, if your Windows hard drive is still locked, how to unlock Windows 10/8/8.1? Try method 2.

Step 1: You have to prepare an installation disc or repair disk, either USB or CD/DVD.
Tip: You’d better use the installation disc which is for the same edition of Windows you are trying to repair.
Step 2: Connect the installation disc to your computer and boot from it to get the window below (here we take Windows 10 installation disc for example):
Step 3: Choose a language, a time, a currency, a keyboard, or an input method, and then click Next to continue.

Когда у вас на ПК произошла любая ошибка BSOD и вы перезагрузили систему, то можете столкнуться с ошибкой, что диск на котором установлена windows заблокирован. Эта ошибка может появится в Windows 10, Windows 7 и Windows 8.1, и связана она с повреждением системных файлов, битые сектора на диске, MBR или BCD. Когда вы пытаетесь попасть в дополнительные параметры загрузки, чтобы исправить ошибку, то получите сообщение об ошибки «Диск на котором установлена Windows, заблокирован. Разблокируйте диск и попробуйте снова«. Даже когда попытаетесь перезагрузить в дополнительных параметрах, то получите сообщение «Невозможно перезагрузить компьютер. Требуемый раздел диска отсутствует». Давайте разберем, как исправить ошибку, когда диск заблокирован.
Исправить ошибку, когда диск с Windows заблокирован
Если в дополнительных параметрах вы проделываете ниже описанные шаги, и получаете сообщения об ошибках, то нужно создать установочную флешку и загрузиться через нее в дополнительные параметры. Рекомендую сначала проделать исправления без установочной флешки. Когда создадите установочную флешку с Windows, дойдите до пункта установки Windows и ниже нажмите на «Восстановление системы«, чтобы попасть в дополнительные параметры загрузки.
Внимание: Первым делом нажмите в дополнительных параметрах на «Восстановление при загрузке». Если не помогло, то двигаемся ниже и запускаем CMD.
1. Проверка диска и восстановление системных файлов
Когда вы попали в дополнительные параметры, то перейдите «Устранение неполадок» > «Дополнительные параметры» > «Командная строка«. В командой строке проделайте две команды, перезагружая ПК после каждого выполненного процесса.
chkdsk /r
— Исправит ошибки на диске. Перезагрузите ПК.sfc /scannow
— Восстановит системные файлы. Перезагрузите ПК.
2. Восстановление данных конфигурации загрузки
Откройте обратно командную строку и введите следующие команды, нажмите Enter после каждой, чтобы исправить данные конфигурации загрузки (BCD).
bootrec /FixMbr
bootrec /FixBoot
bootrec /ScanOs
bootrec /RebuildBcd
Выше метод может не работать для некоторых пользователей. В этом случае пропустите и проделайте способы ниже. Если ничего не помогло ниже, то этот способ поможет вам восстановить загрузчик Windows при разных разметках GPT UEFI или MBR BIOS.
4. Проверить активен ли раздел
Ошибка «Диск на котором установлена Windows, заблокирован. Разблокируйте диск и попробуйте снова» может возникнуть, если основной раздел диска MBR больше не настроен как активный. В этом случае запустите командную строку и введите команды по очереди.
Этот способ подойдет к старому BIOS разметкой MBR. Если у вас UEFI с GPT, то не делайте данный способ.
diskpart
— Запуск инструмента.list disk
— Отображает все подключенные диски к ПК.select disk 1
— Выбор диска. Выберите диск на котором Windows.list partition
— Показывает разделы на выбранном диски.select partition 3
— Выбрать локальный раздел на диске для активации. Выбирайте тот раздел, где написано «Зарезервирован«.active
— Активировать раздел.
Если у вас нет раздела «Зарезервирован«, то изначально Windows была установлена не правильно. В этом случае, выбирайте тот раздел, где установлена сама система Windows. Ниже на картинке, Windows у меня установлена как Раздел 4. В этом случае нужно
select partition 4
, а не 3.
Если у вас ноутбук с UEFI, то откат к заводским настройкам запускает специальная утилита от разработчика ноутбука, которая установлена в скрытый раздел. Запустить данную программу можно прямо в работающей Windows, загрузившись через безопасный режим или установочную флешки войдя через нее в безопасный режим. Если Windows не загружается, то нажимайте многократно F12 при включении ноутбука и запустите восстановление заводских настроек ноутбука. Кнопки могут быть разные, все зависит от производителя ноутбуков. Воспользуйтесь Google картинками, что нажимать при включении ноутбука, чтобы запустить сброс заводских настроек.
