Steps to fix FAT FILE SYSTEM Windows 10 error
Solution 1 – Update your Windows and drivers
Most commonly BSoD errors are caused by outdated or incompatible drivers, so in order to fix this problem we urge you to download the latest drivers for your motherboard, chipset, graphic card and other devices that you have installed. You can download all the necessary files from the manufacturer’s website.
In addition to downloading the latest drivers, it’s also rather important to download and install Windows 10 updates. Microsoft is working hard on finding and fixing the hardware and software conflicts, and in some cases FAT FILE SYSTEM can be fixed by performing a Windows 10 update.
Update drivers automatically
Searching for drivers on your own can be time-consuming. So, we advise you to use a tool that will do this for you automatically. Using an automatic driver updater will certainly save you from the hassle of searching for drivers manually, and it will always keep your system up to date with the latest drivers.
Tweakbit’s Driver Updater (approved by Microsoft and Norton Antivirus) will help you update drivers automatically and prevent PC damage caused by installing the wrong driver versions. After several tests, our team concluded that this is the best-automatized solution.
Here is a quick guide on how to use it:
- Download and install TweakBit Driver Updater
- Once installed, the program will start scanning your PC for outdated drivers automatically. Driver Updater will check your installed driver versions against its cloud database of the latest versions and recommend proper updates. All you need to do is wait for the scan to complete.
- Upon scan completion, you get a report on all problem drivers found on your PC. Review the list and see if you want to update each driver individually or all at once. To update one driver at a time, click the ‘Update driver’ link next to the driver name. Or simply click the ‘Update all’ button at the bottom to automatically install all recommended updates.
Note: Some drivers need to be installed in multiple steps so you will have to hit the ‘Update’ button several times until all of its components are installed.
Solution 2 – Run the BSOD Troubleshooter
The next tool we’re going to use is Windows 10’s built-in troubleshooter. This tool can help with dealing with all sorts of system issues, including the BSOD errors.
Here’s how to run Windows 10’s built-in BSOD troubleshooter:
- Open the Settings app and go to Update & Security section.
- Select Troubleshoot from the menu on the left.
- Select BSOD from the right pane and click Run the troubleshooter.
- Follow the instructions on the screen to complete the troubleshooter.
Solution 3 – Run the SFC scan
The next troubleshooting tool we’re going to try is the SFC scan. This is a command-line tool that serves as a system scanner, and it’s as effective as basically any other troubleshooting tool out there.
Here’s how to run the SFC scan in Windows 10:
- Right-click on the Start Menu button, and open Command Prompt (Admin).
- Enter the following line and press Enter: sfc/scannow
- Wait until the process is done (it may take a while).
- If the solution is found, it will automatically be applied.
- Now, close the Command Prompt and restart your computer.
Solution 4 – Run DISM
And finally, the last troubleshooting tool we’re going to use is DISM. This tool deploys the system image all over again, so it’s quite possible it’ll eliminate potential BSOD errors. Including the FAT FILE SYSTEM error (hopefully).
We’ll walk you through both standard and the procedure that utilizes the installation media below:
- Standard way
- Right-click Start and open Command Prompt (Admin).
- Paste the following command and press Enter:
- Wait until the scan is finished.
- Restart your computer and try updating again.
- With the Windows installation media
- Insert your Windows installation media.
- Right-click the Start menu and, from the menu, choose the Command Prompt (Admin).
- In the command line, type the following commands and press Enter after each:
- dism /online /cleanup-image /scanhealth
- dism /online /cleanup-image /restorehealth
- Now, type the following command and press Enter:
- DISM /Online /Cleanup-Image /RestoreHealth /source:WIM:X:SourcesInstall.wim:1 /LimitAccess
- Make sure to change an X value with the letter of the mounted drive with Windows 10 installation.
- After the procedure is finished, restart your computer.
Solution 5 – Try starting your computer with only one hard drive
As we already mentioned FAT FILE SYSTEM is usually caused by your hard drive, and you can sometimes fix this problem by disconnecting your second hard drive and starting Windows 10 without it. If you don’t have two or more hard drives, you can skip this solution and try a different one.
In order to disconnect your hard drive, you’ll have to open your computer case, and disconnect the power cable that connects to your hard drive. Make sure to do this for all hard drives except for the one that has Windows 10 installed on it.
In addition to internal hard drives, users are suggesting to remove any additional memory cards and USB drives that you might have connected to your PC. If the FAT FILE SYSTEM BSoD error is fixed after disconnecting additional hard drives, you can turn off your computer and try reconnecting them one by one until you find the one that is causing FAT FILE SYSTEM error to appear.

Solution 6 – Check your hardware is working properly
Blue Screen of Death errors can be often caused by a faulty hardware, and if that’s the case, you should find the faulty hardware and replace it. If your hardware is new and recently installed, it could be that it’s not compatible with your PC. In case you don’t have any recently installed hardware, this means that your current hardware isn’t working properly.
Few users reported that a faulty motherboard is the cause of this issue, so make sure to check your motherboard. Bear in mind that almost any other hardware can cause this issue, and if you need help in diagnosing the faulty hardware, it’s best that you take your PC to the repair shop.
Solution 7 – Uninstall Folder Protect and Folder Lock software
Certain folder protection and encryption software can cause FAT_FILE_SYSTEM to appear. According to users, software such as Folder Protect and Folder Lock can cause BSoD error since their encryption method interferes with your hard drive. If you use these any of these tools, only solution is to uninstall them from your computer.
Few users reported that they can’t even access Windows 10, so they cannot uninstall this software. If FAT FILE SYSTEM error prevents you from accessing Windows 10, you can try to uninstall these tools from Safe Mode. To access Safe Mode you need to do the following:
- While your computer boots restart it. You’ll have to repeat this step few times before your PC starts Automatic Repair process.
- Choose Troubleshoot > Advanced options > Startup settings and click on Restart. When your computer restarts, press F5 or 5 to access Safe Mode with Networking.
After accessing Safe Mode you should be able to delete the problematic software without any problems.
Solution 8 – Uninstall your antivirus software
Due to incompatibility issues, certain antivirus software can cause FAT FILE SYSTEM error to appear. If you are having this error on Windows 10, we advise you to remove your currently installed antivirus software and check if that fixes the issue.
If the issue persists even after the antivirus software is removed, you might have to use special uninstaller to remove your antivirus software. Many antivirus companies offer tools that will uninstall their antivirus software completely, so make sure that you download one of these tools and use it to remove your antivirus.
If removing your antivirus software fixes the issue, you should install a different antivirus software on your PC. We did a list of best antivirus programs for Windows 10 and we advise you to check it out.
Solution 9 – Reset Windows 10
If all other solutions fail, you can reset Windows 10. Bear in mind that resetting Windows 10 will remove all your installed applications, so you’ll have to download and install them again. To reset Windows 10, you’ll need to do the following:
- While your computer boots restart your PC couple of times. This should start the Automatic Repair.
- Choose Troubleshoot > Reset this PC.
- You can choose between Keep my files and Remove everything options. The first option will install Windows 10 again, but it will not remove your personal files and folders. The second option will delete all files and folders that you have on your C drive. If the first option isn’t working for you, you can always repeat these steps and choose the Remove everything option.
- The process of resetting will now start, so make sure that you don’t interrupt it.
If the reset option doesn’t help, you can always perform a clean reinstall and format your hard drive partition completely. Bear in mind these procedures will delete some of your files and folders, so make sure that you have a backup available.
