Как восстановить загрузчик EFI Windows 7 и Windows 10?

windows failed to start

В этой статье мы попробуем восстановить загрузчик EFI для Windows 7/8/10. Чуть ранее мы уже разбирали восстановление загрузки для таблицы MFT на примере Windows 7. Сейчас же позволю себе сразу отметить, что повреждение загрузчика в нашем случае чаще всего (помимо прочего) вызывается:

  • установкой второй операционной системы
  • неправильными операциями по восстановлению системы (или неудачным её завершением)
  • удалением неких данных из скрытых разделов
  • битыми секторами на носителе с Windows
  • действием зловредов.

С помощью представленных инструментов можно будет попробовать восстановить загрузчик EFI, который отказывается загрузить систему из-за отсутствующего или битого файла конфигурации по адресу:

Скрытый диск:EFIMicrosoftBootBCD

Вот, кстати, его примерное содержимое из Heren’s BootCD:

содержимое раздела EFI

  • Структура Windows 7/10 в режиме загрузки UEFI
  • Попробуем переписать файл конфигурации напрямую
  • Пересоздаём раздел EFI из-за Ошибки доступа в bootrec
  • Не получается?
  • На будущее: резервную копию BCD можно было создать самому.

Чтобы было понятно…

Структура разделов в таблице GPT на Windows, загруженной в режиме UEFI, чаще всего выглядит так:

структура диска GPT таблицы с поддержкой UEFI Windows 7

где

  • EFI — раздел ESP (Extensible Firmware Interface) — раздел, где хранится программное обеспечение с драйверами, обеспечивающими загрузку Windows;
  • MSR — он же Microsoft Reserved — резервируемый во время установки Windows раздел; его вполне может и не быть на вашей машине
  • Первичный раздел — том, где хранятся системные файлы: реестр, службы, системные утилиты, файлы настроек и т.д.

Windows 10 сюда добавляет ещё и диск Восстановления. По умолчанию (т.е. при установке Windows на НЕФОРМАТИРОВАННЫЙ диск), первые два раздела имеют чёткий объём. И потому по необходимости их легко вычленить, ориентируясь только лишь на размеры обоих. В Windows 7, например, это соответственно 100 Мб и 128 Мб. И это, как говорится, типовая конфигурация. Некоторые производители компьютеров создают разделы по своему усмотрению, например, засовывая туда среду восстановления Windows PE в файл winre.wim. Если вы обнаружили у себя такой файл, знайте, что именно он содержит в себе образ восстановления системы от производителя. Раздел EFI обязателен на GPT дисках с UEFI поддержкой. Когда компьютер включается, среда UEFI загружает загрузчик (EFIMicrosoftBootbootmgfw.efi) из раздела EFI (ESP), передавая той контроль над загрузкой самой Windows. Нет раздела — нет загрузки.

где вы хотите установить windows

Раздел же MSR на диске создаётся для облегчения обзора разделов и используется для системных операций (типа конвертации диска из простого в динамический). Это резервный раздел, которому Windows никогда не присваивает опознавательные знаки. И данных пользователя он не содержит. В Windows 10 размер раздела MSR — 16 Мб (в Windows 8 — 128 Мб), тип файловой системы — NTFS.

Данные конфигурации загрузки Windows

О том, что файл по указанному выше адресу EFIMicrosoftBootBCD повреждён, вам может сообщить синий экран смерти BSOD с ошибкой следующего содержания:

The boot configuration data for your PC is missing or contains errors.
File :EFIMicrosoftBootBCD
Error code: 0xc0000***

Это означает, что данные в файле Boot Configuration Data не распознают конфигурацию загрузчика вашей Windows. Однако, пользователей, знакомых с утилитой восстановления загрузчика в MFT bcdedit.exe, в этот раз та не выручит. При попытке её запустить, пользователь увидит непривычное:

The boot configuration data store could not be found.
The requested system device cannot be found

Мол, ни данных, ни самого устройства не существует. Причина одна: раз конфигурация загрузчика BCD в UEFI-режиме загрузки лежит в специальном разделе EFI:

efi раздел

efi раздел в Windows 7

управление дисками в windows 10

efi раздел в Windows 10

…то наша утилита просто его не видит. Т.е. не видит сам загрузчик, а то и весь раздел. В общем, не спасают и традиционные средства восстановления, созданные на такой случай:

Как восстановить загрузчик EFI Windows 10: в лоб.

  • выбираем загрузочное устройство, вызвав меню быстрой загрузки клавишами в зоне F или через BIOS

pop up menu быстрой загрузки

  • загружаем с флешки с Windows 10 PE;
  • выходим на командную строку, зажав Shift + F10 после появления окна Установка Windows
  • как и в предыдущем режиме, нам нужно определиться со списком разделов компьютера. Далее я предполагаю, что жёсткий диск установлен в единственном экземпляре:
diskpart
list volume
  • обнаруживаем EFI раздел. Его размеры, повторюсь, невелики (100 Мб в W7 и W10), и он имеет файловую систему FAT32:

list volume diskpart

у меня EFI — это безымянный Том 3

  • по умолчанию он скрыт, а значит не имеет буквы. Для дальнейшей работы она нам понадобится. Так что присваиваем букву прямо сейчас:
select volume *
assign letter Y:
exit

присвоить букву тому в diskpart

После закрытия программы отправляемся в этот раздел:

cd /d Y:EFIMicrosoftBoot

Здесь появляется небольшое отступление. Этот путь существует по умолчанию, и причин, чтобы консоль вам отказала в переходе в указанную папку, нет. Если ошибка появилась, см. абзац Возможные ошибки или сразу переходите к следующей части Как восстановить загрузчик EFI Windows 7/10: пересоздаём EFI.

bootrec fixboot отказано в доступе

меня ошибка Отказано в доступе настигла сразу

  • создаём заново загрузочный сектор одноимённого раздела:
bootrec /fixboot
  • используя утилиту bcdedit.exe создадим хранилище заново, копируя загрузочные файлы из системной папки:
bcdboot C:Windows /l ru-ru /s k: /f ALL

где

/f ALL – скопирует загрузочные файлы (и UEFI и BIOS режимов) для возможной поддержки загрузки на EFI и BIOS;

/l ru– ru — укажет на языковую локаль системы, которая будет использоваться, т.е. на русскую. Если всё проходит без ошибок, пропускайте абзац.

  • выполняем последовательно следующие команды:
bootrec /scanos
bootrec /rebuildbcd

Перезагружаемся в Windows 10 на жёстком диске и проверяем.

Возможные ошибки

Администратора здесь могут подстерегать некоторые ошибки. Среди них наиболее часто появляются:

  • BFSVC Error: Can not open the BCD template store. status – [c000000f] –
    нужно проверить вводимые команды и путь к хранению системных файлов Windows; иногда ошибка появляется из-за неправильного указания языковой локали;
  • BFSVC Error: Error copying boot files from Last Error = 0x570 – ошибка является следствием самого явления, что Windows не загружается. Вероятно, плохие сектора появились не только в разделе загрузки EFI, но и на диске с системой; прогоните жёсткий диск утилитой chkdsk.exe тут же из консоли командой
chkdsk с: /а

где с — диск с системой

  • Отказано в доступе — причин на то множество: от наличия плохих секторов до неверно выставленного режима загрузки (стоит Legacy вместо UEFI; нужно — только UEFI) с флешки. Однако. UEFI не был бы UEFI, если бы всё проходило вот так гладко: то, что раздел EFI не подпускает к своим файлам — это, скорее закономерность, чем исключение. Так что, если в доступе вам отказано, я советую вам просто сначала удалить сам раздел EFI (а он такой нам больше не нужен), воссоздать его заново с единственно необходимой для его работы директорией, а затем уже положиться на ремонтную bootrec, позволив ей завершить работу. Так что, если необходимость возникла, продолжаем работу с момента появления отказа команде
bootrec /fixboot

Как восстановить загрузчик EFI Windows 7/10: пересоздаём EFI.

Самое главное здесь — не промахнитесь с разделом/лами и не удалите тот из них, в котором хранятся данные Windows и ваша информация. Итак, раз bootrec.exe попасть в нужный нам раздел не смогла, раздел убираем. Для этого нам будет нужно вернуться в diskpart.exe, снова определиться с разделами и выбрать тот, что на 100 Мб. Возвращаемся в ремонтную консоль:

cd /d x:

вернуться в diskpart

И начинаем заново:

diskpart
select disk 0
list partition
select partition 2

удаляем его:

delete partition override

удалить раздел в diskpart

можно проверить результат:

list partition

У нас осталось некоторое нераспределённое пространство, в котором мы заново создаём удалённый только что раздел:

create partition efi size=100
list partition
select partition 2
format quick fs=fat32 label="System"

форматирование в diskpart

Но при попытке присвоить применявшуюся ранее букву Y, консоль ответила отказом (надо было её перезапускать). Я присвою разделу букву Z:

assign letter=Z
exit

Подготовим почву для bootrec.

  • создаём папку загрузки:
mkdir Z:EFIMicrosoftBoot

создание новой папки EFI на системном диске

  • копируем туда файлы из состава среды EFI из папки установленной Windows (С — буква диска с системными файлами Windows):
xcopy /s C:WindowsBootEFI*.* Z:EFIMicrosoftBoot
  • пусть bootrec с вашей флешки проверит диски на предмет системных файлов Windows:
bootrec /scanos

Никуда они не денутся, если вы их случайно не удалили, или они не попали в зону бэд-секторов. Остаётся…

  • … заставить написать «правильный» файл BCD и прочие «конфиги»:
bootrec /rebuildbcd

bootrec scanos rebuildbcd

Выключаем компьютер, флешку вынимаем и включаем машину. Ждём появления Windows. Дайте ей загрузиться до Рабочего стола и проверяйте, всё ли на месте.

Ошибка вновь появляется…

Не беспокойтесь. Если вы вникли в процесс, и все команды вводили осознанно и корректно, ситуация, скорее всего, уже исправлена. Просто следует учесть особенности своеобразных фильтров безопасности, принятых для режима UEFI, и не путать буквы дисков. Их можно пройти, проделав такие шаги:

  • Разбудите BIOS:
    — снимите крышку боковую компьютера или нижнюю ноутбука
    — отключите жёсткий диск (отключив оба шлейфа на «стационарнике» или вынув из разъёмов на ноутбуке)
    — включите машину, дождавшись ошибки загрузки;
    — выключив компьютер, подключите жёсткий заново и снова, включив компьютер, проверьте;
  • проверьте UEFI меню платы компьютера на предмет правильной очерёдности разделов загрузки; первым должен стоять, как вы поняли, именно EFI;
  • убедитесь, что метка Загрузочный стоит только напротив EFI раздела, и ни у какого больше. Проверить и исправить ситуацию из Windows PE, к сожалению, не получится. И для этого придётся воспользоваться дополнительными инструментами в виде загрузочной флешки. Сделайте это любым удобным вариантом из статьи Метка диска Загрузочный: как добавить или удалить?

У меня всё. Успехов.

Opening and accessing .EXE files can sometimes be difficult for Windows users, even if they are using the latest version of Windows. Many queries related to the same were submitted on Microsoft forums, and still, no viable solution was provided to resolve this query.

There are cases in which users even receive error messages when they try to open a .exe file, like Access Denied, Runtime Error, etc. So, what is the actual reason behind this problem?

Cause of .EXE Not Opening

According to Microsoft experts, this problem occurs due to corrupt registry settings, or system issues due to virus infection or third-party tool installations. Installation of third-party software can change the default configuration for running EXE files, which often leads to failures when you try to run EXE files.

Well, fixing this problem is very easy and convenient without using any third-party tools.

Methods to Open .EXE Files in Windows 10

There are multiple ways to resolve this error; here, we will cover the most useful methods for fixing “EXE files not opening in Windows 10.”

  1. By changing the registry values
    Due to unknown reasons, the values in your system registry often get changed that prevent .exe files from opening. You can change the default registry settings, following the below steps:

    • Press Window + R on your system and type cmd to launch Command prompt.
    • On the command prompt, type regedit and press enter.
    • Registry Editor will appear on the screen, in the left pane, click HKEY_CLASSES_ROOT.exe.
    • In the right pane, you’ll see Registry keys. Click the Default key and set the data value to exefile.
    • After changing the key value, click HKEY_CLASSES_ROOTexefileshellopencommand key in the left pane.
    • Just like above, click the Default key and change its value to “%1” %*.
    • Now, restart your computer, and see if the problem is fixed or not.

    For some users, this method might work in the Safe mode. However, if it still doesn’t work for you, then check other methods mentioned below.

  2. Turn off Windows Firewall
    Every genuine Windows comes integrated with Firewall protection to protect the system from external malware attacks. Disabling Windows Firewall can also fix this issue, as reported by some users. To disable Windows Firewall, you’ll have to launch your computer in Safe Mode, and then follow the below steps:

    • After starting the computer in Safe Mode, press Window + S to enter Windows Firewall and select Windows Firewall from there.
    • In the left pane, click Turn Windows Firewall on or off. In the opened wizard, select Turn Off Windows Firewall for both Private network settings and Public network settings, and then click OK to save changes.
    • After turning off the Windows Firewall, check if the problem is still persisting or not.

    Well, it is NOT RECOMMENDED to disable Windows Firewall on your system, as it protects your data from malicious attacks. But, if disabling it fixes some problems, then you can give it a try.

General Suggestions for Fixing .EXE File Errors

Using the above methods, you can easily resolve the problems in opening the .exe file. But, if you’re still unable to access your .exe file, then you can follow some general tips, such as:

  1. Use System File Checker
    It is an in-built tool provided by Microsoft to help users repair their data files. Using this software, you can scan Windows and restore files.
  2. Try Clean Boot for your System
    Clean boot is the process of starting your Windows with minimal programs and services. And when your Windows start with minimal resources, you can use hit and trial method to find the third-party application that is harming your files.

    To start your system in Clean Boot, you need to run msconfig command in the Run dialog box, which will display the System Configuration Utility.

    Go to the Services tab and hide all the Microsoft services, then click the Startup tab to locate the culprit software and disable it. Now, reboot your system, and you’ll not face the problem again.

  3. Install Latest Updates
    Check for Windows 10 latest updates and install on your system. If the latest updates are not installed, then download and install it because sometimes .exe files are unable to open in old versions.

To check for Windows 10 updates, go to System settings>>Update & Security, and then click Windows Update.

In case, if the Windows system is corrupt, then none of the solution will work for you. However, you can use Windows Data Recovery software that will help you recover files of your system.

Download Now

Conclusion

EXE is an executable file format used by various applications. But users sometimes find it difficult to open and access their .exe files on Windows systems. Windows Data Recovery will recover all the files present in Windows system including the EXE files. So, whenever you are facing problems or errors in opening the executable files, then you scan the drive using Windows Data Recovery and retrieve the EXE files that will run properly now.

If Windows refuses to let you open a file, try these fixes to gain access once more.

how to fix these files cant be opened error on windows

Did you just try to open a file on Windows and receive an error that said, «These files can’t be opened«? The error mostly occurs for .exe files, but some users have also encountered it with other file types too. The issue is most commonly encountered on Windows 7 and 8, but you can still encounter it on a Windows 10 PC.

Fortunately, fixing the error shouldn’t take you longer than finishing a cup of coffee. What could take a tad longer though is determining the cause of the error so you can apply the appropriate fix. From Internet Properties to Internet Explorer settings, there could be several reasons that could cause the error.

Whatever the cause, one of the following fixes will set you up so you can access those files again without feeling like pulling your hair out.

1. Check If Your File Is Blocked

Sometimes, when you download an executable file off the internet or transfer files among PCs, Windows may decide to block the file to protect your system. When this happens, you’ll witness the error «These files can’t be opened«, but a two-step fix is all you need to unblock this file.

To illustrate this behavior here, we downloaded the 4K Video Downloader’s setup file onto a PC. Windows didn’t block access to this file for us, but it did warn us under the Security section in the File Properties > General tab.

unblock a file from file properties

The message says «This file came from another computer and might be blocked to help protect this computer.» If you’re unable to access the file, you can fix it by checking the Unblock box and pressing OK. If you’re on a different version of Windows, you may see a button instead of a checkbox, but the process is the same.

Once you’re done, try running the file and see if everything is back on track.

2. Change Your Internet Properties

Windows checks your Internet Properties when deciding if a file should be allowed to run on your PC. If your Internet Properties marks a file as unsafe, Windows will give you the «These files can’t be opened» error. As such, to change Windows’ behavior, you’ll need to make some changes to your Internet Properties.

Note that this will require you to make your security settings less stringent from the Internet Properties. While you may be able to fix the error by doing this, it will also make your system vulnerable to security threats if you’re not mindful of which files you download onto your system.

If you decide to take this route, start by opening Internet Properties. To do this, press Win + R, type inetcpl.cpl, and press Enter. Switch to the Security tab in the Internet Properties window and click on the Custom level button.

change internet properties by pressing custom level

You’ll now see a window called Security Settings — Internet Zone. Scroll through the list under the Settings section and look for Launching applications and unsafe files.

allow unsafe files to be run on your system

Make sure that the radio button for Prompt (recommended) is selected. This option is typically selected by default, but if you’ve tinkered with your internet properties in the past, you may have inadvertently changed it to Disable.

Once you’re done, click OK and see if you’re able to run the file.

3. Try Editing Values in the Windows Registry

If the previous fixes didn’t work for you, you can also try allowing unsafe files by editing the Windows registry. You’ll need to add a new registry entry using the Command Prompt. Start by launching elevated Command Prompt by pressing Win + R, typing cmd, and pressing Ctrl + Shift + Enter.

Execute the following commands one by one:

 reg add "HKCUSoftwareMicrosoftWindowsCurrentVersionPoliciesAssociations" /v "DefaultFileTypeRisk" /t REG_DWORD /d "1808" /f
reg add "HKCUSoftwareMicrosoftWindowsCurrentVersionPoliciesAttachments" /v "SaveZoneInformation" /t REG_DWORD /d "1" /f

This will add two new registry keys. Once you’re done, restart your PC and try opening the files.

4. Reset Internet Explorer

If you use Internet Explorer, resetting the settings to default could be helpful. To reset Internet Explorer’s settings, click on the ellipsis icon at the top-right of the browser and click on Internet Options. Switch to the Advanced tab and click on the Reset button.

revert internet explorer back to default settings

When prompted, confirm the reset and then reboot your PC.

If you still can’t run the files you want, perhaps it’s time for a last resort.

5. Revert Your Computer to a Previous System Restore Point

If you were able to run a particular file in the recent past but started getting this error after messing around with some settings, you could restore your system to a previous state where everything was going swimmingly.

To do this, you’ll first need to make sure that you have a system restore point created on your PC. Start by pressing Win + R, typing rstrui, and pressing Enter. This will launch the System Restore window. If you do have a restore point, you’ll see one under the Recommended restore option.

check system restore points

If you don’t have a restore point, you’ll see a message, «No restore points have been created on your computer’s system drive.» This means your PC has no point of reference in the past to revert to, and as such, you cannot use this method to fix your issue.

If you do have a restore point on your system, choose the recommended restore point or choose a different one based on when the problem started occurring, and click on Next. Continue following the wizard’s prompts. Once the system is restored, your PC will reboot and you should now be able to run the files you want.

Can You Open the Files Now?

Hopefully, one of these fixes worked for you and you’re no longer receiving the These files can’t be opened error. If you still are, however, you could try to reset your PC. All settings on your Windows will revert back to default, and some of your files may be lost in the process, so it’s good practice to create a backup before you reset.
