How can I get into Safe Mode on the new Windows operating systems such as Windows 8, Windows 10 and Server 2012? Starting from Windows 8, the system boots very quickly and the time to press F8 key to access Safe Mode is smaller than 200 milliseconds, so it’s almost impossible to enter into the Safe Mode by pressing F8 during boot time.

In this tutorial we’ll show you 3 workable ways to boot Windows Server 2012 into Safe Mode. The methods should also work with Windows 10 and Windows 8/8.1.

Method 1: Boot Windows Server 2012 into Safe Mode Using Command Prompt

  1. Press the Windows key + X to open the WinX menu, select “Command Prompt (Admin)” from the list.

    winx

  2. In order to make Windows display the Windows Boot Manager, type the following command at the Command Prompt and press Enter. You will get a confirmation stating that The operation completed successfully.

    bcdedit /set {bootmgr} displaybootmenu yes

    enable-display-boot-menu

    If you want to stop displaying the Windows Boot Manager later, run this command instead:
    bcdedit /set {bootmgr} displaybootmenu no

  3. Now restart your computer and you’ll see the Windows Boot Manager screen. Just press F8 to bring up the Advanced Boot Options.

    windows-boot-manager

  4. Select Safe Mode and press Enter. This will open Windows Server 2012 in Safe Mode.

Method 2: Boot Windows Server 2012 into Safe Mode Using System Configuration

  1. Press the Windows key + R to open the Run box. Type msconfig and press Enter.

    msconfig

  2. Now the System Configuration dialog box will be opened. Under the Boot tab, check the Safe boot option and click OK.

    safe-boot

  3. Reboot your computer and it will boot directly into Safe Mode automatically. If you wan to stop Windows from booting into Safe Mode next time, you need to open the System Configuration utility (msconfig) again and uncheck the Safe boot option.

Method 3: Boot Windows Server 2012 into Safe Mode Using Settings App

  1. To get started, you need to open the Settings panel. This can be done by hovering your mouse to the top right-hand corner of the screen, or press the Windows key + I on your keyboard.
  2. Hold down the SHIFT key on your keyboard, and then click on Power icon and select Restart.

    shift-restart

  3. You will need to click on the Troubleshoot option.

    choose-an-option

  4. Click Startup Settings.

    advanced-options

  5. Click Restart.

    startup-settings

  6. The computer will boot automatically to the Advanced Boot Options screen. From there you can select Safe Mode to start Windows Server 2012 in Safe Mode.

  • Способ 1. Использование параметров запуска
  • Способ 2: использование msconfig

Безопасный режим — это режим в Windows, который позволяет получить доступ к специальным функциям. Эти функции часто используются для устранения неполадок.

Для того, чтобы загрузиться в безопасном режиме, вам нужно будет иметь нормальный доступ к вашему Windows Server. Это означает, что вы можете получить доступ к вашему Windows Server с помощью пользователя и иметь права администратора.

Используйте любой из способов ниже, чтобы загрузить сервер в безопасном режиме.

Способ 1. Использование параметров запуска

Чтобы включить безопасный режим с помощью графического интерфейса, нажмите Windows + C , откройте «Настройки», затем нажмите «Питание». Затем зажмите Shift и нажмите «Перезагрузить».

Нажмите «Устранение неполадок», затем «Параметры запуска». Нажмите «Перезагрузить» после подтверждения того, что в отображаемом списке написано «Включить безопасный режим».

Используйте клавиши со стрелками для перехода в безопасный режим. При нажатии Enter после перехода в безопасный режим ваш Windows Server будет загружен в безопасный режим.

Ваш фон должен быть черным, а в верхнем правом углу графического интерфейса должно быть написано «Безопасный режим».

Способ 2: использование msconfig

Вы также можете загрузиться в безопасном режиме с помощью настройки системы ( msconfig). Для этого перейдите в Run и запустите msconfig.

На вкладке «Загрузка» в разделе «Параметры загрузки» выберите «Безопасная загрузка». Затем нажмите «ОК», и сервер перезагрузится в безопасном режиме. Нажмите «Перезагрузить», если вам будет предложено.

При загрузке в безопасном режиме фон рабочего стола будет черным, а в правом верхнем углу рабочего стола появится надпись «Безопасный режим».

Where has Server 2012 Safe Mode gone — Startup Settings missing too?!

  • Question

  • Hi, I desperately need Safe Mode (No Networking etc) in Windows 2012 RTM as the server is down because a bad network driver is generating BSOD due to IRQL_NOT_LESS_OR_EQUAL. This should be simple to disable… but in Win 2012 it isn’t!

    I have already seen the articles about how F8 is different now (useful feature change in emergencies…) but if you use Shift-F8 you should get into the Troubleshoot -> Advanced Options, and phew, I can do that just about (after many long reboots and
    F8 mashing — it’s a luck thing) — however am stunned to find that slightly contrary to article screenshots, I have the icons for:

    • System Restore
    • System Image Recovery
    • Automatic Repair
    • Command Prompt
    • Startup Settings — oh no, hang on — this one is NOT THERE!!!

    Naturally, Startup Settings is the one I need to switch this cursed thing into Safe Mode! So why is it not there on some servers — I wasn’t aware that there were any hardware dependencies for this. It’s an HP ProLiant DL120 G7, but
    this is an OS issue, not straight hardware (in which case I’d expect the setting to be there but cause an error/warning).

    This may be something to do with the OS being in Recovery Mode etc — but that is the whole point of needing Safe Mode! So what is the way to get into that please, so I can simply disable the bad driver and get on with our business?

    Phil

Answers

  • Hi,

    To enable Safe Mode, please try the following:

    1. If you can boot into Windows, please open a privileged command prompt.

    2. If not, please boot into recovery mode and run command prompt.

    3. In the command prompt, please input

    Bcdedit /set {bootmgr} displaybootmenu yes

    4. Once completed, please restart your computer, then press F8 to enter setup screen upon startup, then press F4 or 4 to enter safemode.

UPDATED: March 2018

If you have worked on Windows 8 or newer, you will know that Microsoft has removed the F8 boot functionality.  They did this to decrease boot times.  What is odd is that they applied this logic to servers; I would not have.  Regardless the F8 Safe Mode functionality is not truly removed, it is just turned off.

To turn F8 boot on in Server 2012 you need to get to an elevated CMD prompt.  Windows-Server-2012-R2-Setup-Repair-your-computerWindows-Server-2012-R2-Setup-Repair-Your-Computer-Troubleshooting-Command-Prompt If your server is functional that is easy.  If your server won’t boot (hence the need for F8) then you can boot off of a Windows Server install DVD and select REPAIR YOUR COMPUTER option, the Troubleshooting, then Command Prompt.

Once you have a Command Prompt (as an administrator) open enter the following commands which are self explanatory:

  1. bcdedit /set {bootmgr} displaybootmenu yes
  2. bcdedit /set {bootmgr} timeout 10

Reboot your machine and enjoy pressing F8 and getting back into SAFE MODE or LAST KNOWN GOOD to work out your problem.

This will also work on Windows 8 and Windows 10.

Note that the BCDEDIT commands do NOT work from PowerShell.   They NEED to be run from CMD.EXE :

Thanks to a number of blogs including THIS one.

How to Boot Windows Server into Safe Mode

Introduction

In this article, you will learn how to boot windows server into safe mode.

Safe Mode is an unique Windows boot-up mode that can be used to restart the computer once a major problem has occurred that interferes with normal Windows functions and activities. Safe Mode enables users to debug and find the root cause of a fault.

In safe mode, an operating system has reduced functionality; however, the process of isolating problems is facilitated by the fact that many non-essential components, such as sound, are disabled. An installation that will only boot into safe mode typically has a significant issue, such as disc corruption or the installation of software with improper configuration, which prevents the operating system from successfully booting into its normal operating mode and allowing the user to use the computer as intended.

A user is normally granted access to utility and diagnostic programs when operating in safe mode. This enables the user to investigate and resolve issues that prevent the operating system from functioning normally. The functionality of the system is not meant to be used while in safe mode, and user access to features is severely restricted.

You have to login into your window server.

Step 1. On the right side of the window, search cmd and click on Command Prompt.

Step 2. Now run the msconfig command.
