Solution 1 – Update Windows 10 and all your drivers

Keeping your Windows 10 safe and free from errors is important, and the simplest way to do that is to download the latest updates. Microsoft is releasing new updates frequently, and you can download them by using Windows Update. Many of these updates offer new features and security improvements, but updates also include many bug fixes related to both hardware and software, therefore be sure that you download them.

In addition to downloading Windows updates, it’s also important that you update your drivers. Your hardware requires drivers in order to work with your operating system, therefore it’s highly recommended that you download and install the latest drivers. Updating drivers is fairly simple, and to install the latest drivers you just need to visit your hardware manufacturer’s website and download the latest drivers for your device. Bear in mind that you will have to update all drivers on your PC in order to fix this error.

Installing the latest drivers is crucial for system stability, but downloading drivers manually can be long and tedious. If you want to quickly update all your drivers, we suggest that you try this Driver Update software.

Windows 10 usually downloads the missing updates automatically, but sometimes due to certain bugs you might miss an update or two. However, you can always check for updates manually by doing the following:

  1. Press Windows Key + I to open the Settings app. Now navigate to Update & Security section.
    Fltmgr_file_system Windows 8
  2. Now click the Check for updates button.

Windows will now check for available updates. If any updates are available, they will be downloaded in the background. Once the updates are downloaded, they will be installed as soon as you restart your PC. After the updates are installed, check if the problem still persists.

Solution 2 – Temporarily remove your antivirus software

Third-party applications can often cause this error to appear, especially if that application isn’t fully compatible with Windows 10, or if it has certain bugs. To fix this error it’s recommended that you locate and remove the problematic application.

A common cause for FLTMGR_FILE_SYSTEM and other Blue Screen of Death errors can be your antivirus software, and users reported issues with AVG and Symantec, but bear in mind that almost any antivirus software can cause this error to appear. To fix this problem you’ll have to temporarily remove your antivirus, and the best way to do that is to use the dedicated removal tool.

Uninstalling the antivirus software isn’t enough because many applications tend to leave certain files and registry entries behind once you remove them, therefore we strongly suggest that you use the dedicated removal tool to clean any remaining files. If you’re using AVG you can download the removal tool for it from AVG support section. Almost all security companies have these tools available for their software, so be sure to download and use one.

If your antivirus was the problem, it’s highly recommended to switch to a different antivirus solution. There are many great antivirus tools available, but the best are Bitdefender, Bullguard, and Panda Antivirus, so feel free to try any of them. All these tools offer great protection and they are fully compatible with Windows 10, so you won’t experience any issues while using them.

Solution 3 – Enter Safe Mode

If the issue is caused by certain software, you’ll be able to tell that by entering Safe Mode. This mode uses only the necessary drivers and software, and if the error is caused by third-party software, you shouldn’t see a BSOD error while in Safe Mode. To enter Safe Mode, do the following:

  1. Start Automatic Repair by restarting your computer few times during the boot sequence. Alternatively, you can hold Shift on your keyboard and click the Restart button.

  2. Choose Troubleshoot > Advanced options > Startup Settings and click the Restart button.
  3. When your computer restarts you’ll see a list of options. Press 5 or F5 to start Safe Mode with Networking.

If your PC is stable in Safe Mode it means that the BSoD is being caused by certain software on your PC, so you can use the Safe Mode to find and remove the problematic software.

Solution 4 – Perform a chkdsk scan

Run a System Scan to discover potential errors

Run a PC Scan with Restoro Repair Tool to find errors causing security problems and slowdowns. After the scan is complete, the repair process will replace damaged files with fresh Windows files and components.

According to users, sometimes FLTMGR_FILE_SYSTEM error can occur due to file corruption. If that’s the case, you might have to repair your files in order to fix this problem. To do that, you need to start Command Prompt before Windows 10 starts and run the chkdsk scan. This is rather simple and you can do it by following these steps:

  1. Restart your PC several times during the boot to force you computer to start in Automatic Repair mode.
  2. Choose Troubleshoot > Advanced options. Now select Command Prompt.
  3. When Command Prompt starts, enter chkdsk /f X: and run that command. Keep in mind that you have to replace X with the letter that represents your system partition. It’s worth mentioning that your drive letters might be different while using Command Prompt outside Windows, so keep that in mind.

You should also know that chkdsk scan can take 15 minutes or more depending on the size of your partition. Once the scan is finished, check if the problem still persists.

Solution 5 – Use System Restore

Sometimes you can encounter FLTMGR_FILE_SYSTEM error due to recently installed applications or updates. If the problem started occurring recently, you might be able to fix it by performing System Restore.

If you’re not familiar, System Restore is a useful feature that allows you to easily restore your PC to the previous state in order to fix many problems. To perform System Restore outside of Windows 10, you need to do the following:

  1. Restart your PC several times during the boot sequence.
  2. Now choose Troubleshoot > Advanced options > System Restore.
  3. Select your user name from the list and enter your account password.
  4. System Restore window will now appear. Click on Next to continue.

  5. If available, check Show more restore points and select the desired restore point. Click Next and follow the instructions on the screen to complete the restoration process.

If System Restore fixes the problem, keep a close eye on new software and driver updates. Windows 10 tends to update your drivers automatically, and sometimes a driver update can cause this error to appear.

To prevent this problem from reappearing, be sure to block automatic Windows Updates and block Windows 10 from updating certain drivers. Blocking the updates isn’t always the best solution, but sometimes it’s necessary if you want to prevent this issue from reappearing.

Solution 6 – Perform Windows 10 reset

If you cannot find the software that is causing FLTMGR_FILE_SYSTEM BSOD error, you can perform a Windows 10 reset. This procedure will delete all files from your C partition, therefore be sure to back up your important files. To complete Windows 10 reset, you might also need a bootable USB flash drive, and you can use Media Creation Tool to create one. To perform Windows 10 reset, do the following:

  1. Restart your PC few times during the boot sequence.
  2. Select Troubleshoot > Reset this PC > Remove everything. During this step you might be asked to insert Windows 10 installation media, so be sure to do that.
  3. Select Only the drive where Windows is installed > Just remove my files and click the Reset button to start.
  4. Follow the instructions on the screen to complete the reset process.

After you complete Windows 10 reset, don’t install any third-party applications, instead just test your system for a while. If the error appears again, it means that the issue is caused by your hardware.

Solution 7 – Check for faulty hardware

Often cause for FLTMGR_FILE_SYSTEM error can be faulty hardware, most commonly RAM, therefore we advise you to test your RAM modules one by one and check if they are are working properly.

Sometimes you don’t even have to replace your RAM, it’s enough to reseat your RAM modules and the problem should be fixed. Bear in mind that dust can also cause this problem to appear, and if your memory slots are filled with dust, you need to remove your RAM and clean the slots with pressurized air. Another common cause for this error can be your motherboard, so be sure to check if it’s working properly.

FLTMGR_FILE_SYSTEM Blue Screen of Death error can cause you problems, but you can easily fix this error by removing the problematic applications, or by reseating your RAM modules.
