A recent hardware or software change

A recent hardware or software change

Сообщение об ошибке «Windows failed to start. A recent hardware or software change might be cause…» часто появляется при неправильной переустановке ОС Виндовс и реже при каких-либо неполадках с комплектующими компьютера. Текст ошибки так и переводится «Невозможно загрузить операционную систему Windows. Проблемы могут быть на аппаратном или программном уровне».

Ошибка Windows failed to start

Устраняем ошибку при помощи переустановки Windows с флешки

Для того, чтобы решить проблему, нам понадобиться установочная флешка с утилитой от Microsoft или любая другая для создания образов диска. Вы должны иметь загрузочную флешку, которую необходимо вставить в USB разъем проблемного компьютера. Операционную систему желательно выбрать от 7 версии.

  1. Перезагрузите компьютер.
  2. Заходим в BIOS при помощи специальной клавиши, которая для каждой материнской платы своя, чаще всего это клавиша DEL.
  3. Откройте раздел биоса «Boot Menu», или что-то подобное, может быть одно слово «Boot».
  4. Теперь нашей задачей является установить флешку первым в загрузочной иерархии. По умолчанию загрузка производится из жесткого диска. Вам необходимо знать название вашего съемного накопителя, для этого можно подсмотреть в разделах дисков при записи на нее Windows.
  5. После чего нажмите F10 для сохранения изменений меню и перезагрузите компьютер.
  6. При появлении строки внизу экрана «Press any kay from CD or DVD» нажмите любую из клавиш, чтобы запустилась загрузка с флешки и началась установка Windows.
  7. Далее процесс установки обычный, как и с диска, только в конце, система попытается перезагрузить ваш ПК для входа в оконный режим, нужно будет в момент отчета до перезагрузки вытащить флешку. После этого система загрузиться и настроит самостоятельно компоненты для работы.

Тестируем компьютер на неисправности

Предыдущим способом можно устранить ошибку «Windows failed to start. A recent hardware or software change might be cause…» на программном уровне, но что делать, если ошибка кроется в сбое на аппаратном уровне? Для этого существуют специальные программы, которые способны тестировать все компоненты компьютера на работоспособность. Рассмотрим одну из таких программ, которая называется Aida 64. Она на является самой популярной из-за своей многофункциональности и при этом небольшого размера. Скачать ее можно на странице http://www.aida64.ru/download.

Скачайте ее и запустите.

  • Перейдите в окне программы на вкладку «Тест», которую можно найти внизу слева в списке.
  • Здесь предоставлены варианты для тестирования различных компьютерных компонентов, таких как память, процессор и т.д. Предоставляются возможности проверить компьютер на задержки в памяти, записи в память, жесткий диск на наличие нерабочих, поврежденных секторов, работоспособность модулей оперативной памяти.
  • Чтобы выбрать тест, нажмите одну из предложенных проверок в левом окне и нажмите кнопку старт.
  • Для проверки всех компонентов компьютера, нажмите в верхнем баре «Отчет».
  • Откроется окно «Мастер отчетов» для продолжения нажмите кнопку «Далее».

  • Из предложенных вариантов выберите «Аппаратные разделы». Выберите вариант отчета и дождитесь завершения процесса.
  • Проблемы с жестким диском способна вызывать ошибку

    Когда у вас стоит два жестких диска на компьютере или компьютер имеет вставленную флешку, то скорее всего проблема в том, что неправильно совершается процесс запуска ОС. Для этого нужно снова зайти в BIOS.

    • Нажмите кнопку при перезагрузке Windows, чтобы попасть в настройки BIOS.
    • Находим пункт Boot.
    • В пункте Priority (у вас может назваться по-другому) выставляем на первую позицию диск, который содержит операционную систему.

    Выбор диска в меню BIOS

  • После чего нажмите F10 и подтвердите клавишей «Y».
  • Если вы столкнулись с ошибкой «Windows failed to start» – отключите и отсоедините все накопители и USB-устройства от компьютера и попробуйте запустить систему снова.

    Преобразование жесткого диска из MBR в GPT и обратно

    Проблема может решиться изменением типа разделов диска. Для этого в системе есть специальная функция. При этой процедуре вся информация будет удалена. Поэтому решите для себя сами, подходит ли вам этот вариант. Чтобы узнать в чем разница между дисками MBR и GPT перейдите по ссылке.

    1. Попытайтесь запустить систему в безопасном режиме, нажав F8 при старте компьютера.
    2. Откройте «Командную строку».
    3. Затем введите поочередно следующие команды компьютеру – «list disk» и нажмите «Enter».
    4. Следующая команда «select disk #» — вместо звездочки номер диска в приоритете загрузки, нажмите «0» и Ввод.
    5. Команда «clean», и Enter. Это очистит все разделы диска.
    6. Далее пропишите «convert mbr» и подтвердите нажатием Enter. Эта команда конвертирует диск в MBR.

    После завершения процесса закройте все окна и перезапустите компьютер. Проделав такие манипуляции с диском ошибка «Windows failed to start. A recent hardware or software change might be cause…» должна исчезнуть.

    In this tutorial, I demonstrate two possible ways to fix this Windows startup error that says Windows failed to start, a recent hardware or software changes might be the cause, with the error code 0xc00000f or 0xc0000225.

    1. This first solution is on the hardware side, so the first thing you want to do it to check that your C drive or the disk drive where you have your operating system, is properly attached to the connector on your computer.

    2. The second solution is for situation where certain application or malware changes the path variables on your boot manger, hence making it unable to locate your Windows boot files during startup.

    Summary

    There are several reasons why a Windows-based computer may have problems during startup. To troubleshoot boot problems, first determine in which of the following phases the computer gets stuck:

    Phase Boot Process BIOS UEFI
    1 PreBoot MBR/PBR (Bootstrap Code) UEFI Firmware
    2 Windows Boot Manager %SystemDrive%ootmgr EFIMicrosoftBootootmgfw.efi
    3 Windows OS Loader %SystemRoot%system32winload.exe %SystemRoot%system32winload.efi
    4 Windows NT OS Kernel %SystemRoot%system32
    toskrnl.exe

    1. PreBoot

    The PC’s firmware initiates a Power-On Self Test (POST) and loads firmware settings. This pre-boot process ends when a valid system disk is detected. Firmware reads the master boot record (MBR), and then starts Windows Boot Manager.

    2. Windows Boot Manager

    Windows Boot Manager finds and starts the Windows loader (Winload.exe) on the Windows boot partition.

    3. Windows operating system loader

    Essential drivers required to start the Windows kernel are loaded and the kernel starts to run.

    4. Windows NT OS Kernel

    The kernel loads into memory the system registry hive and additional drivers that are marked as BOOT_START.

    The kernel passes control to the session manager process (Smss.exe) which initializes the system session, and loads and starts the devices and drivers that are not marked BOOT_START.

    Here is a summary of the boot sequence, what will be seen on the display, and typical boot problems at that point in the sequence. Before starting troubleshooting, you have to understand the outline of the boot process and display status to ensure that the issue is properly identified at the beginning of the engagement.

    Each phase has a different approach to troubleshooting. This article provides troubleshooting techniques for problems that occur during the first three phases.

    If the computer repeatedly boots to the recovery options, run the following command at a command prompt to break the cycle:

    Bcdedit /set recoveryenabled no

    If the F8 options don’t work, run the following command:

    Bcdedit /set bootmenupolicy legacy

    BIOS phase

    To determine whether the system has passed the BIOS phase, follow these steps:

    1. If there are any external peripherals connected to the computer, disconnect them.
    2. Check whether the hard disk drive light on the physical computer is working. If it is not working, this indicates that the startup process is stuck at the BIOS phase.
    3. Press the NumLock key to see whether the indicator light toggles on and off. If it does not, this indicates that the startup process is stuck at BIOS.

    If the system is stuck at the BIOS phase, there may be a hardware problem.

    Boot loader phase

    If the screen is completely black except for a blinking cursor, or if you receive one of the following error codes, this indicates that the boot process is stuck in the Boot Loader phase:

    • Boot Configuration Data (BCD) missing or corrupted
    • Boot file or MBR corrupted
    • Operating system Missing
    • Boot sector missing or corrupted
    • Bootmgr missing or corrupted
    • Unable to boot due to system hive missing or corrupted

    To troubleshoot this problem, use Windows installation media to start the computer, press Shift+F10 for a command prompt, and then use any of the following methods.

    Method 1: Startup Repair tool

    The Startup Repair tool automatically fixes many common problems. The tool also lets you quickly diagnose and repair more complex startup problems. When the computer detects a startup problem, the computer starts the Startup Repair tool. When the tool starts, it performs diagnostics. These diagnostics include analyzing startup log files to determine the cause of the problem. When the Startup Repair tool determines the cause, the tool tries to fix the problem automatically.

    To do this, follow these steps.

    For additional methods to start WinRE, see Windows Recovery Environment (Windows RE).

    Start the system to the installation media for the installed version of Windows. For more information, see Create installation media for Windows.

    On the Install Windows screen, select Next > Repair your computer.

    On the System Recovery Options screen, select Next > Command Prompt.

    After Startup Repair, select Shutdown, then turn on your PC to see if Windows can boot properly.

    The Startup Repair tool generates a log file to help you understand the startup problems and the repairs that were made. You can find the log file in the following location:

    %windir%System32LogFilesSrtSrttrail.txt

    Method 2: Repair Boot Codes

    To repair boot codes, run the following command:

    To repair the boot sector, run the following command:

    Running BOOTREC together with Fixmbr overwrites only the master boot code. If the corruption in the MBR affects the partition table, running Fixmbr may not fix the problem.

    Method 3: Fix BCD errors

    If you receive BCD-related errors, follow these steps:

    Scan for all the systems that are installed. To do this, run the following command:

    Restart the computer to check whether the problem is fixed.

    If the problem is not fixed, run the following command:

    You might receive one of the following outputs:

    If the output shows windows installation: 0, run the following commands:

    After you run the command, you receive the following output:

    1. Try restarting the system.

    Method 4: Replace Bootmgr

    If methods 1, 2 and 3 do not fix the problem, replace the Bootmgr file from drive C to the System Reserved partition. To do this, follow these steps:

    At a command prompt, change the directory to the System Reserved partition.

    Run the attrib command to unhide the file:

    Run the same attrib command on the Windows (system drive):

    Rename the Bootmgr file as Bootmgr.old:

    Navigate to the system drive.

    Copy the Bootmgr file, and then paste it to the System Reserved partition.

    Restart the computer.

    Method 5: Restore System Hive

    If Windows cannot load the system registry hive into memory, you must restore the system hive. To do this, use the Windows Recovery Environment or use Emergency Repair Disk (ERD) to copy the files from the C:WindowsSystem32configRegBack to C:WindowsSystem32config.

    If the problem persists, you may want to restore the system state backup to an alternative location, and then retrieve the registry hives to be replaced.

    Kernel Phase

    If the system gets stuck during the kernel phase, you experience multiple symptoms or receive multiple error messages. These include, but are not limited to, the following:

    A Stop error appears after the splash screen (Windows Logo screen).

    Specific error code is displayed. For example, "0x00000C2" , "0x0000007B" , "inaccessible boot device" and so on. Advanced troubleshooting for Stop error 7B or Inaccessible_Boot_Device

    The screen is stuck at the "spinning wheel" (rolling dots) "system busy" icon.

    A black screen appears after the splash screen.

    To troubleshoot these problems, try the following recovery boot options one at a time.

    Scenario 1: Try to start the computer in Safe mode or Last Known Good Configuration

    On the Advanced Boot Options screen, try to start the computer in Safe Mode or Safe Mode with Networking. If either of these options works, use Event Viewer to help identify and diagnose the cause of the boot problem. To view events that are recorded in the event logs, follow these steps:

    Use one of the following methods to open Event Viewer:

    Click Start, point to Administrative Tools, and then click Event Viewer.

    Start the Event Viewer snap-in in Microsoft Management Console (MMC).

    In the console tree, expand Event Viewer, and then click the log that you want to view. For example, click System log or Application log.

    In the details pane, double-click the event that you want to view.

    On the Edit menu, click Copy, open a new document in the program in which you want to paste the event (for example, Microsoft Word), and then click Paste.

    Use the Up Arrow or Down Arrow key to view the description of the previous or next event.

    Clean boot

    To troubleshoot problems that affect services, do a clean boot by using System Configuration (msconfig). Select Selective startup to test the services one at a time to determine which one is causing the problem. If you cannot find the cause, try including system services. However, in most cases, the problematic service is third-party.

    Disable any service that you find to be faulty, and try to start the computer again by selecting Normal startup.

    If the computer starts in Disable Driver Signature mode, start the computer in Disable Driver Signature Enforcement mode, and then follow the steps that are documented in the following article to determine which drivers or files require driver signature enforcement: Troubleshooting boot problem caused by missing driver signature (x64)

    If the computer is a domain controller, try Directory Services Restore mode (DSRM).

    This method is an important step if you encounter Stop error "0xC00002E1" or "0xC00002E2"

    Examples

    Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

    Error code INACCESSIBLE_BOOT_DEVICE (STOP 0x7B)

    To troubleshoot this Stop error, follow these steps to filter the drivers:

    Go to Window Recovery Environment (WinRE) by putting an ISO disk of the system in the disk drive. The ISO should be of same version of Windows or a later version.

    Open the registry.

    Load the system hive, and name it as "test."

    Under the following registry subkey, check for lower filter and upper filter items for Non-Microsoft Drivers:

    HKEY_LOCAL_MACHINESYSTEMControlSet001ControlClass

    For each third-party driver that you locate, click the upper or lower filter, and then delete the value data.

    Search through the whole registry for similar items. Process as an appropriate, and then unload the registry hive.

    Restart the server in Normal mode.

    For additional troubleshooting steps, see the following articles:

    To fix problems that occur after you install Windows updates, check for pending updates by using these steps:

    Open a Command Prompt window in WinRE.

    Run the command:

    If there are any pending updates, uninstall them by running the following commands:

    Try to start the computer.

    If the computer does not start, follow these steps:

    Open A Command Prompt window in WinRE, and start a text editor, such as Notepad.

    Navigate to the system drive, and search for windowswinsxspending.xml.

    If the Pending.xml file is found, rename the file as Pending.xml.old.

    Open the registry, and then load the component hive in HKEY_LOCAL_MACHINE as a test.

    Highlight the loaded test hive, and then search for the pendingxmlidentifier value.

    If the pendingxmlidentifier value exists, delete the value.

    Unload the test hive.

    Load the system hive, name it as "test".

    Navigate to the following subkey:

    HKEY_LOCAL_MACHINESYSTEMControlSet001ServicesTrustedInstaller

    Change the Start value from 1 to 4

    Unload the hive.

    Try to start the computer.

    If the Stop error occurs late in the startup process, or if the Stop error is still being generated, you can capture a memory dump. A good memory dump can help determine the root cause of the Stop error. For details, see the following articles:

    For more information about page file problems in Windows 10 or Windows Server 2016, see the following:

    For more information about Stop errors, see the following Knowledge Base article:

    If the dump file shows an error that is related to a driver (for example, windowssystem32driversstcvsm.sys is missing or corrupted), follow these guidelines:

    Check the functionality that is provided by the driver. If the driver is a third-party boot driver, make sure that you understand what it does.

    If the driver is not important and has no dependencies, load the system hive, and then disable the driver.

    If the stop error indicates system file corruption, run the system file checker in offline mode.

    To do this, open WinRE, open a command prompt, and then run the following command:

    If there is disk corruption, run the check disk command:

    If the Stop error indicates general registry corruption, or if you believe that new drivers or services were installed, follow these steps:

    1. Start WinRE, and open a Command Prompt window.
    2. Start a text editor, such as Notepad.
    3. Navigate to C:WindowsSystem32Config.
    4. Rename the all five hives by appending ".old" to the name.
    5. Copy all the hives from the Regback folder, paste them in the Config folder, and then try to start the computer in Normal mode.
