Hello! Windows Server is a system focused on the business sector. In addition, Microsoft developed it as a safe, functional, and practical system. However, it is also susceptible to failure. Such as errors in drivers, services, or parameters of both the system itself and other components. To solve this type of failure, the Redmond company has incorporated the Safe Mode. With this mode, the system will start in a basic state. In other words, it will only make use of a limited set of files and drivers. Consequently, it will be much easier to rule out bugs and problems. So by being able to enter the system using this mode, we can then reverse any changes responsible for the malfunction. For that reason, it is important to know how to use this function. So let’s see, how to start in safe mode in Windows Server 2019/2016.

How to start in safe mode from the system.

Before we go any further, it is important to clarify that the safe mode has two options:

• Safe mode: load basic controllers.
• Safe mode with network functions. Includes network drivers and services needed to access the Internet and other computers on the local network.

In order to set up the safe mode, it is necessary to start the system in the advanced mode. If you are running the system, then you have a couple of options to start in advanced mode:

• Press the Shift key and the off button at the same time. Once there, click on restart.
• Press the Win+I combination to enter the Windows Settings. Then follow the path: Update & Security> Recovery. Once there, click on Restart Now.

How to start in safe mode, using a Windows Server 2019/2016 installation media.

For this method, it is necessary to have some means of installing Windows Server. Either a DVD or a USB boot. Then, you have to start the process as if you were going to install the system. On the welcome screen, click on Next.

Please click on Repair computer.

A window with several options will be displayed immediately. Please click on Troubleshoot.

Then select Command Prompt:

This will cause the CMD to be deployed. Please run this command:

bcdedit /set {bootmgr} displaybootmenu yes

This is a command line tool to manage the data associated with the boot configuration of the system.

Once this line is executed, we will execute the following:

bcdedit /set {bootmgr} timeout 15

After executing this command, execute the Exit command to exit the console. And back to the previous menu, turn off the system.

When you reboot the system, you will see the boot manager. Please select Windows Server. Then, press F8 to enter advanced start options.

Then, just click on Safe Mode to start the system.

Eventually, the system will boot into Safe Mode.

Conclusion

Ultimately we have seen how to start in Safe Mode in Windows Server 2019/2016. This mode allows you to start the system with a minimum of drivers and files. This allows for troubleshooting. In addition, these instructions are common to both versions. I hope you find them useful in managing your servers. Before saying goodbye, I invite you to see our post about VMware on Windows 10. See you!

Можно ли загрузить Windows Server 2016 в командной строке таким образом, чтобы диски и файловые системы оставались там, где они находятся? Я не ищу безопасный режим. Когда я нажимаю F8 при загрузке, я могу попасть в меню «безопасный режим» (там, конечно, есть и другие варианты). Однако мой C: не имеет такой же структуры папок, и у меня есть новый диск «X: ». Я хотел бы попасть в командную строку, в которой диски оставлены в покое, а у меня нет этого нового диска X: с «некоторым» из того, что было на C :. В моем C: есть только две папки с файлами Program, и все. Это возможно?

Windows Server is an operating system of the business type which has been developed by Microsoft in order that as administrators we have at hand the possibility of managing in a centralized way various roles and services focused on each client having the best services ..

Windows Server has been developed as a safe, functional and practical system, but like every system developed by man, it is not free from failures and for this reason we can find errors in the drivers, services or parameters of both the system itself and others components and hence the importance of knowing how to fully manage the system.

For this type of administration and support, Microsoft has integrated the Safe Mode function into Windows Server 2016 or 2019. With the safe mode, the Windows operating system will boot into a basic state , that is, it will only use a limited set of files and drivers to perform administration tasks in a much more complete way..

This will give us better perspectives regarding the solution of the problems that the equipment may have, seen from this mode, it will be much simpler to rule out failures, for example, if the system works normally in this safe mode, we can rule out that both the default configuration As the basic device drivers are not the root cause of the problem and thus it will be possible to concentrate on other aspects of the system.

TechnoWikis will explain how we can start Windows Server, in this case 2019, in safe mode, but it is ideal to remember that this process applies equally to Windows Server 2016..

To configure the safe mode in Windows Server 2019, we must start the system in advanced mode and for this we have several options that are:

• Use the Shift key and press the Windows Server shutdown button and select Restart there

• Go to the Start / Configuration / Update and security / Recovery path and click on the Restart now button in the Advanced Start section

Step 1

The third method, which we will use in this tutorial, is to use the ISO image of Windows Server 2019 or 2016 either through the DVD or a bootable USB. With this available, we must access the BIOS or UEFI of the computer and there configure the boot method in the Boot tab as well. Press the F10 key to save the changes.

• Removable Devices: USB Devices

• CD-ROM Drive: DVD Drive

Step 2

Once the boot process starts, press any key to configure Windows Server 2019 startup:

Step 3

There we click on «Next» and we will see this:

Step 4

There we click on the «Repair the equipment» line and we will be redirected to the following window (the same one using one of the previous methods):

Step 5

There we select the «Troubleshoot» option and in the next window we select the Command Prompt option:

Step 6

By selecting this option, we will access the command prompt of the Windows Server where we will enter the following line:

 bcedit / set {bootmgr} displaybootmenu yes 

Step 7

Once this line is executed, we will execute the following.

 bcedit / set {bootmgr} timeout 15 

Step 8

When starting the system, we will see the following:

Step 9

There we select our operating system and later it will be possible we will select the type of boot in safe mode that we want for Windows Server 2019:

Step 10

Press Enter and once we access the system it will be possible to perform the required administrative tasks:

Thus, we have learned to access in this practical and useful way in Windows Server 2016 or 2019 to perform the necessary administration tasks.

Safe Mode is a special mode on Windows systems that is mainly used for troubleshooting purposes. If there is any issue to boot Windows successfully due to virus, malicious software, or driver installation, you can boot the system into Windows safe mode and fix the issues.

See the instructions for booting into Safe Mode by using Windows Recovery Tools, Command Prompt(cmd), or System Configuration on the Windows server below.

Using Windows Recovery Tools

One of the common ways to access Safe Mode for Windows servers is to get into the Windows Recovery options. The below steps outline the methods for this when the server is online as well as when it is having issues starting up normally.

When the server does not start up Windows normally

When the server fails to start up Windows normally more than once, it will automatically present the Windows Recovery option to access advanced repair options.

When the server is accessible with Windows able to start up normally

When the server is online, the Windows Recovery Environment can be accessed from inside the server once it is logged in using two methods.

NOTE: It is advised that the below steps be performed while accessing the server through Console option under LayerPanel 2.

1. Using the Restart button in the server.

   This is done by holding down the Shift key while clicking the Restart button.

   

   OR

2. Using the Update & Security option.

   a) Click on Windows Start menu and then click on Settings.

   

   b) Click on Update & Security.

   

   c) Click on Recovery in the left panel and then on Restart Now under Advanced startup section.

   

Using Troubleshooting option to start Safe Mode

1. Once the server is restarted by following either of the above-specified methods, the server will be rebooted into the Troubleshooting screen as below. Click on Troubleshoot to continue to steps.

   

2. In the Advanced options screen, click on Startup Settings.

   

3. In the Startup Settings screen, click on the Restart button.

   

4. Once the server is restarted, the Advanced Boot Options screen will show up, from where the Safe Mode option can be selected for booting up the server further.

   

Using Command Prompt (cmd)

1. To open the Command prompt, just click on the Windows key to open start and search cmd, and then click on the Command Prompt which is shown in the below image.

   

2. Now get the command prompt interface and run the below command to display the Boot manager.

   > bcdedit /set {bootmgr} displaybootmenu yes
   

   

   NOTE: Run the below command to stop showing the Boot manager

   > bcdedit /set {bootmgr} displaybootmenu no
   

   

3. Now restart the server to see the Windows Boot Manager screen. Once it has been done, press F8 to go to the Advanced Boot Options.

   

4. From the Advanced Boot Options, select the Safe Mode that is shown in the below image and press Enter. It will open Windows Server 2019 in Safe Mode.

   

Using System Configuration

1. Open the run box by pressing the Windows key and search Run, and then type msconfig in the run box and press Enter.

   

2. Once it has been done, will get the System Configuration dialog box. Check the Safe boot option and click OK Under the Boot tab as shown in the below image.

   

3. Now reboot the server and then it will boot directly into Safe Mode automatically.

   NOTE: To stop boot into safe mode, un-tick the Safe boot option and click OK Under the Boot tab.

Иногда необходимо выполнить загрузку компьютера с минимальным набором драйверов, системных программ и ПО, которое запускается автоматически, например, при необходимости выполнить низкоуровневые операции с операционной системой, при удалении вирусов, программном сбое или удалении специального ПО. 
Итак, чтобы перейти в безопасный режим, необходимо при старте операционной системы зажать кнопку F8. Должен появиться черный экран с выбором вариантов загрузки.

В безопасном режиме можно загрузиться без поддержки сети, в этом случае компьютер не будет загружать драйверы сетевых устройств, и компьютер будет вне сети, а можно с поддержкой сетевых устройств, в этом случае сеть будет работать в штатном режиме.

В настоящее время, многие современные компьютеры загружаются достаточно быстро  и можно не успеть нажать F8 в нужным момент. В этом случае, если компьютер успешно загружается в штатном режиме, можно использовать штатную утилиту Microsoft управления параметрами загрузки: MSConfig. 

Как выполнить загрузку Windows в безопасном режиме

Если необходимо выполнить запуск компьютера в безопасном режиме, то необходимо выполнить следующие действия:

1. Нажмите сочетание клавиш Win + R.
2. В открывшемся окне ввести команду msconfig, а затем нажать кнопку OK.
3. Перейти на вкладку Boot.
4. В разделе Boot Options Установить флажок Safe boot (и указать необходимые пункты) и нажать OK
5. Перезагрузить компьютер

После перезапуска, компьютер будет запущен в безопасном режиме

Как отменить загрузку Windows в безопасном режиме

Если необходимо выйти из безопасного режима, то выполните следующие действия:

1. Нажмите сочетание клавиш Win + R.
2. В открывшемся окне ввести команду msconfig, а затем нажать кнопку Ок.
3. Перейти на вкладку Boot.
4. В разделе Boot Options снимите флажок Safe boot.
5. Перезапустить компьютер

После перезапуска, компьютер будет запущен в обычном режиме

Safe Mode

Note

BCDEdit is a command line tool developed by Microsoft thanks to which it will be possible to manage the data associated with the system’s boot configuration (BCD).

Note

Once this process is done, we execute the exit command to exit the command line and proceed to turn off the computer to eliminate it and to be able to configure the boot again from the hard disk.

Always eager to communicate with other system engineers and administrators. I enjoy all aspects of my job, designing, deploying and updating server, desktop, network and storage systems. I blog regularly and contribute wherever possible to the Microsoft community.

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?
