Fix Boot Device Not Found 3F0 Error

Receiving a screen of death is not a pleasant experience at all and most users would agree that they would very much like not to face one during their work with the computer. Sadly PC is not a perfect machine and it is not working in a perfect environment so errors happen. The most famous and well-known death screen is blue which is also the most common one, my bet would be that there is not a user which has not been faced with this blue error screen. There is no simple explanation why these stop errors occur as several factors can be involved. However, it is known that the malfunctioning of hardware drivers or drivers that are installed by third-party software drive this unwanted change. But did you know that there is more colors for infamous death screens and not just blue one? Microsoft has coded different errors to different colors in the goal for the technical team to be aware right away of what type and kind of error they are dealing with. Color for screen errors are: Blue, Black, Pink, Brown, Yellow, Red, Orange, Green and White If you are interested in what color represents what keep reading.

BLUE

A stop error or exception error commonly called the blue screen of death (BSoD) or blue screen, is an error screen displayed on Windows computers following a fatal system error. It indicates a system crash, in which the operating system has reached a condition where it can no longer operate safely. This is caused by many different problems, such as a general hardware failure or a crucial process terminating unexpectedly.

BLACK

On Windows 10 systems, a Black Screen of Death can be caused by an unfinished Windows Update. To resolve this problem, simply hold the power button down on your PC or laptop to switch off the computer. A cold start should result in the system booting properly.

---

PINK

It is a diagnostic screen with a white type on a pink background. Pink Screen is mainly seen when the VMkernel of an ESX/ESXi host experiences a critical error, becomes inoperative, and terminates any virtual machines that are running. It is not fatal and generally considered more of a developer testing issue. When encountered, it can be fixed quickly by following the simple action of pressing and holding your computer’s power button to shut down the device.

WHITE

The White Screen on Windows is also an error where the screen of the computer just turns white and freezes. There can be several things that can cause the white screen to appear on the Windows laptop monitor. But the main issue could be because of malfunctioning of the graphics hardware.

This post will help you fix the request that failed due to a fatal device hardware error on your Windows 10 PC. You can encounter this error when that hard drive/SSD on your computer is damaged physically and the system is either unable to access or perform read/write operations in it. Aside from hard drive/SSD, this error can also happen to removable drives. This kind of error is not uncommon and in most cases, the hardware is physically damaged due to which you are not able to perform operations. However, there are a couple of fixes that you can try to resolve the problem before you go ahead and back up your data and move them to a different drive. What exactly causes this error? It’s actually self-explanatory and it gives you an idea that the drive is either corrupted or in a bad state. To resolve the error, follow the given options below carefully and see which one worked best for you.

Option 1 – Verify the hard drive using SMART attributes

In case you don’t know, Windows has a built-in feature of SMART analysis which analyzes the hard drive/SSD and checks all the parameters by performing some minor operations. To use it, follow these steps:

• Tap the Win + S keys and type “command prompt” in the field then right-click on the related search result and select the “Run as administrator” option.
• After opening Command Prompt as admin, type the “wmic diskdrive get status” command and hit Enter.
• You should get a result after that, and if you see that it’s “normal”, proceed to the next option below.

Option 2 – Use the CHKDSK utility

When it comes to some issues concerning the hard drive or removable devices, there is a utility in Windows that might help which is called “chkdsk”. This error check utility can help with several issues in the system.

• Tap the Win + S keys to open the Search box.
• Then type “command prompt” in the field and from the search results that appear, right-click on Command Prompt and select “Run as administrator”.
• After opening an elevated command prompt, copy and paste the following command and hit Enter:

CHKDSK [volume [[path] filename]] [/F] [/V] [/R] [/X] [/C] [: size]]

Note: In the command given above, “[/F]” will try to fix the system errors while “[/R]” will be the one to fix the bad sectors.

• Now if you are prompted to run CHKDSK after your reboot your PC, just tap Y and reboot your PC.
• If CHKDSK is not able to find any errors, tap the Win + E keys and navigate the access window. From there, right-click on the concerned drive and click on Properties.
• After opening Properties, click on the tab Tools and then click on the “Check” button under the Error-checking section.
• Wait until the process is completed and then restart your computer.

Option 3 – Format your drive

You can try formatting your drive since this problem also occurs on removable hard drives. In addition, if your drive is not properly initialized, this error will really pop up. Thus, you need to make sure that the hard drive is initialized and that the correct partition style is selected.

• To get started formatting your drive, tap the Win + E keys and then go to the access page of the drive.
• Next, right-click on the drive and select Format.
• After that, uncheck the “Quick Format” option and then format your drive properly.
• Now once the formatting process is finished, unplug the drive and plug it back in afterward.
• Check if the error is already fixed. If the drive is not initialized, tap the Win + R keys and hit Enter.
• After opening the Run dialog box, type “diskmgmt.msc” and hit Enter to open Disk Management.
• From there, right-click on the drive volume and select Initialize Disk.
• Next, select the correct partition type and proceed.

That should fix the problem, if not, follow the next advanced option below.

If you are trying to install a Windows 10 upgrade but was interrupted with an error saying, “0x80070003 – 0x2000D, The installation failed in the SAFE_OS phase with an error during MIGRATE_DATA operation”, then you’ve come to the right place as this post will help you sort this problem out. When you get this kind of error while trying to upgrade your computer, although there could be various reasons for this, the primary one is that when you upgrade from one update to another, something stopped the upgrade process to migrate the user data. To fix this error, you can try to run both the DISM tool and the System File Checker to automatically repair any corrupted system files. You could also try checking the free storage space of your primary drive and if you have any file lock apps like BitLocker, consider disabling them for they could also be the reason why you’re getting the error.

Option 1 – Run the DISM tool

Running the DISM Tool helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10 which might be the reason behind the Windows Upgrade error 0x80070003 – 0x2000D. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt as admin.
• Then type in this command: exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.
• Once it’s done, restart your computer and then check if the issue is resolved or not on the next startup.

Option 2 – Run the SFC scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the Windows Upgrade error to appear. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow and hit Enter.

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Reboot your PC.

Option 3 – Try checking the free storage space on your primary drive

The next option you can try to resolve the error is to see if you have enough free storage space on the primary drive because if you don’t then it’s probably the reason why you’re getting this error. To fix it, you need to free up some storage space by following these steps:

• Open Setting > System > Storage from the WinX Menu.
• From there, you will see a list of all the local and connected storage devices along with the details on the free space.
• Now make sure that the Storage Sense feature is turned On then go find a link that says “Free Up Space” and click it to open.
• After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space:
• Windows Upgrade Log Files
• System created Windows Error Reporting Files
• Thumbnails
• Temporary Internet Files
• Previous Windows Installation Files
• Delivery Optimisation Files
• DirectX Shader Cache

Note: Once you’re done freeing up space on your drive, try to run the setup file again.

Option 4 – Try disabling BitLocker and other file lock apps

If you are using BitLocker or other file lock apps, then it could be the reason why you’re getting the error. Usually, file lock apps don’t cause any kind of issue, however, if you have something that works on file level like BitLocker, you can try to disable it. Once you’ve disabled it, try to install the Windows 10 Upgrade again and after you do, enable BitLocker again. This should fix the problem.

Spending a large amount of time working or gaming in front of the computer can take a toll on your health. And as someone who indeed spends a large amount of time in front of the computer, I would like to share some insights about how can you be happy and healthy at the same time by incorporating some practices and habits.

Get good chair

This is first on the list because it matters the most. A proper sitting chair is essential for back health. If your budget allows it, do yourself a favor and get an anatomic sitting chair or gaming chair with lumbar support. It costs but it is worth it.

Learn to sit properly

As the important chair is, sitting properly is also as important as much. Your spine believe it or not is a very important part of your body and you need to take care of it. Sadly long periods of sitting sessions are bad for muscles around the spine that could reflect on the spine itself. Keep your back straight and keep your head not down nor up, place it in a position like when you are walking so the spine that is going from your head is in line with the spine on your back.

Stretch

By medical standards, each hour of sitting should be accompanied by a stretch session since sitting itself is placing too much pressure on certain muscles and blood circulation is lowered. Changing leg position and doing just a little stretch each hour can be really beneficial for your health in long run.

Take breaks

Yes, playing games is fun and most of the time we do not want to stop playing, especially if we are winning but taking breaks is essential for your personal health. Old saying goes that overdoing anything is bad and this applies true even to things that we do for pleasure and relaxation. Take periodic breaks to stretch, stand up and maybe even walk just a little.

Drink water

During long work hours or long gaming sessions, it is not uncommon that we are so focused on our activity that we forget to take our water intake. Approximately 2liters of water per day is needed for an adult person to function properly during that day and if you spend long times in front of a PC do not forget to drink water.

Do not neglect your daily tasks

As enjoyable as it is gaming can make us forget about our daily tasks, do not neglect your life and your tasks. Remember, gaming is only OK if it does not interfere with the daily things that you need to do. Do not postpone going for groceries because of gaming, do not switch shower for another level in the game. Do all of the things you must do first and then sit and game.

Take care of yourself mentally

Having mental health is as important as having a physical one. Playing games is fun, but playing games with someone is even better, do not forget to socialize and invite some friends so you can share some fun times together. Also, detach yourself from outcomes that will come because of gaming, this is very important for gamers that do a lot of PVP games and get annoyed and angry when they lose or when some other player is talking trash. Remember, gaming is for you to relax and enjoy, not to stress you.

Browsing your files on a computer seamlessly is made possible by the File Explorer in Windows 10 as it provides users with a great sense of customization for both listing and performing operations on a file. You have the option to arrange the folders and files being browsed by their name, type, date, size, and so on. Moreover, files that share a common attribute can be also be grouped accordingly using the grouping feature. However, there are times when instead of helping, it causes some problems for some users. This is why in this post, you will be guided on how you can disable the File Grouping feature in the File Explorer in Windows 10. There are two methods you need to consider in disabling the File Grouping feature in Windows 10. First, you can disable it for only one folder or you can disable it for all the folders on your computer. For more details, follow the instructions given below.

Option 1 – Disable File Grouping in only one folder

• First, open File Explorer, and go to the folder you want to disable File Grouping.
• Next, right-click anywhere on that folder.
• And then select Group by > None. This will disable File Grouping for only that particular folder.

Option 2 – Disable File Grouping in all the folders

If you wish to disable File Grouping in all the folders on your computer, then you need to follow this option. If you have already tried the first one, then continue with the given steps below.

• Tap the Alt + V key combination.
• Then tap the Alt + Y keys and then tap Alt + O keys.
• After that, navigate to the View tab, and under the Folder views section, select Apply to Folders.
• Now click on the Apply and OK buttons to save the changes made. This will disable File Grouping in all the folders listed in the File Explorer.

Computer crashes are one of the most annoying things that can happen to users. It often loses your data and work, you must spend extra time if you were in the middle of something and can even break Windows itself. Before we move to the article I just want to say that technically there are no random crashes, there is always a reason why the system hangs up, why you received blue screen, annoying restarts out of nowhere and many more PC crashes. In this article, we will explore many possible reasons why something may occur and offer you straight forward solution on how to escape the situation and prevent it from happening again. Without further delay, let's begin:

1. Check switch connectors and power outlets

   Yes, sometimes the most basic approach provides the best results, check to see if your power outlet is stable and providing you with constant voltage, if not, maybe you want to invest in a UPS system so you do not face random shutdowns and restarts during work, also while you are at it, check to see if that reset and power switch are connected properly and that they are not dirty or loose.

2. Clean your PC and check connectors

   Dirt can cause many issues with computers, from overheating to shutdowns to blue screens and memory dumps, check to see if your computer is clean enough and that all connectors are connected tight into their respective sockets.

3. Check the temperature of your CPU

   CPU overheating can cause so-called random freezes and blue screens, the computer might shut down or restart also without any visible reason. Check to see if your fan on the CPU is working properly and change the thermal paste if needed.

4. Check the health of your hard drive

   If your hard drive is beginning to go down the path of dying out, many issues can come from this condition. There are many tools on the internet and in Windows itself to check if your hard drive is working properly.

5. Run antivirus and firewall

   Random lock-ups or similar issues can also occur if by any chance you have some malware on your system, run protection software, and keep it updated to make sure the issue does not come from the computer being infected with malicious applications.

6. Keep system clean

   Have a habit to clean regularly system files and registries, keep removing unnecessary files from your computer and regularly update your Windows and applications along with drivers.

7. Run memory test

   Bad RAM bank can cause many issues during the work, check it out to be sure the problem is not RAM itself.

8. Do not run applications that are too demanding for your system

   Some applications require stronger hardware, and some require the latest hardware, if your computer is a little outdated, running a demanding application can cause issues like freezing, restarts, etc.

9. Remove applications you do not use

   This does not seem like anything important but if you are not using a specific application just remove it from the system, why? Sometimes an application has some ties to certain services and if it is outdated can cause issues for newer ones.

10. Stop installing everything you find on the internet

    Yes, that extension for chrome looks cool, yes, that fancy new player seems sick but if it is from an unverified source and from the unknown publisher without any reviews maybe you are better off with it. You can never tell what you might be placing into your system from the internet.

And that's it, 10 reasons and solutions on what to do on random computer freezes, crashes, etc.

What is Error Code 0xC004E003?

Error code 0xC004E003 almost always appears when there are damaged files in the Windows operating system. These files could be corrupt for a number of reasons and are usually a serious danger to the life of the computer system. These file errors may be caused by a number of things. Incomplete installation setup, incorrect deletion of hardware or utilities, or an unfinished file erasure. The trigger might also be in the event that the computer system is contaminated with a virus or adware or spyware, or even by the improper shut down of the computer. Any of these scenarios have the possibility to result in the removal or corruption of data of the Windows system data files.

The data system files that are damaged will give linked data and archives that are missing or wrongly linked. These are needed for the proper functioning of the software. This can also happen when or after installing third-party software that might have changed the system files. If it is suspected that a program installation will need to be stopped, it is best to let it run through the setup and then delete it later. While it installs, it is altering program files, and likely rearranging them. Stopping this in the middle can scramble files associated with the program and files vital to the usage of the computer.

Solution

Error Causes

This error will pop up after installing third-party software that has changed the system files. These system files are necessary to finish the activation process. A restore point will be necessary if it is ultimately determined that a system restore is necessary, to bring the computer back to the state it was in previous to the failed installation.

• Error code “0xC004E003” appears and does not allow the system to continue the install.
• The computer will not allow any further access or installation of the program.
• The computer may crash.
• The third-party program will not have installed completely or successfully.
• The system will not start up correctly.
• Personal files are corrupt or missing.

Further Information and Manual Repair

There are several steps that can be taken when the error code 0xC004E003 appears. It is helpful to know that this can occur from trying to install third party software. Going forward, do not attempt to install third-party software that is not trusted, and does not attempt to abruptly stop the third-party software from installing. This may cause the program to corrupt the files or delete important files. Recovering from this error can be easy if there is a recent restore point already backed up in the recovery portion of the system's files.

• Method One

Run an error scan. The problem should be resolved after rebooting the computer once these steps have been completed.

1. Download and save an error code fix utility.
2. Setup the program and then click the Scan button.
3. Click the Repair Errors button when the diagnostic has been completed successfully.
4. Reboot the computer.

2. Click on Get Started, then select Programs, Accessories, Tools, and then System Restore.
3. On the next screen, click on Restore my PC to an Earlier Period, and then click Next.
4. Select the most recent system restore date within the drop-down menu of “select restore point”.
5. Click Next.
6. Click Next on the confirmation window.
7. Reboot the system after the system has finished restoring.

• Method Three

Another option for restoring. This method can be used by a novice.

1. Right-click on the Start button, then select Control Panel.
2. Look for the Control Panel for Recovery.
3. Select Recovery, then Open System Restore, then Next.
4. Choose the restore point right before the problematic installation.
5. Click Next, click Finish.

NOTE: If there are no restore points available, the system recovery may not be turned on. To check this, go to Control Panel, and select Recovery. Configure System Restore, Configure. Then, select Turn on system protection. Having a current restore point for a computer ensures the ease of recovery if any problems with the computer arise.

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

The Windows 10 operating system supports the logging in of multiple users at the same time. Aside from that, it also allows administrators to create a Guest Account that has limited rights. However, there are some instances when you could encounter an error when you use the Guest Account. The error may state:

“Shell Infrastructure Host has stopped working. A problem caused the program to stop working correctly. Please close the program”.

This error indicates that the Shell Infrastructure Host or SiHost.exe process that is used for handling graphical elements, has crashed. And to fix this error, there are several options you can check out. You can try to reinstall the Microsoft Redistributable Packages or run a System File Checker scan. In addition, you can also use a new Guest Account or troubleshoot the problem in a Clean Boot State.

Option 1 – Try to install or repair Microsoft Visual C++ Redistributable 2013

A corrupted Microsoft Visual C++ Redistributable package or the absence of it can trigger the “Shell Infrastructure Host has stopped working” error – so if you do not have this package yet, you have to install it but if you already have it, follow the steps below to repair it.

• Open Control Panel and proceed to Program and Features.
• Under Programs and Features, look for Microsoft Visual C++ Redistributable package among the list.
• Then right-click on it and click the Change button.
• Next, you should see the Repair option – click on it to repair the installation of the Microsoft Visual C++ Redistributable package.
• The process may take a couple of minutes before it finishes so once it does, you have to restart your PC.

After doing all these steps and you still encounter the problem, you might have to uninstall this package and download it directly from Microsoft’s website. However, if you are using Windows 10, you might not be able to do so since it only supports Windows versions up to Windows 8.1 so just proceed to the next option below.

Option 2 – Try to run a System File Checker scan

• In the Windows Start Search, type “command prompt” and right-click on Command Prompt from the search results, and then select the “Run as administrator” option.
• After opening Command Prompt with admin privileges, type the “sfc /scannow” and tap Enter to execute it.
• Once the scan is finished, restart your computer and see if the Windows Script Host error.

You might want to use a new Guest Account as it could help get rid of the error. All you have to do is have your admin delete the old Guest Account and create a new one and see if it helps in fixing the error.

Option 4 – Try troubleshooting the problem in a Clean Boot State

Setting your computer in a Clean Boot State can help you diagnose and later troubleshoot the problems in your computer. During this state, the system will start with a minimal number of drivers and startup programs that help in isolating the problem with the interfering software. To put your computer in a Clean Boot State, follow the given steps below.

• Log onto your computer as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.

• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Blue Screen of Death errors or Stop errors are indications that something’s wrong with your computer. So when you encounter one, you must find out what the root cause of the problem is before it gets out of hand. One of the BSOD errors you might encounter on your Windows 10 computer is the “DRIVER IRQL NOT LESS OR EQUAL or SYSTEM THREAD EXCEPTION NOT HANDLED, Netwtw04.sys failed” error. As you know, system files or .sys files are some of the essential parts of the Windows operating system. It is a repository of system driver settings used by the Windows operating system in order to communicate with the connected hardware and devices. They are essential for the normal functioning of the operating system. A lot of Windows 10 users are facing this particular Blue Screen of Death error whenever they open an app or disconnect external devices from the system. The Netwtw04.sys file is a part of the Intel PROSet/Wireless Wi-Fi software. And so when you might encounter two kinds of Stop errors for the Netwtw04.sys driver file such as:

1. “DRIVER_IRQL_NOT_LESS_OR_EQUAL What failed: Netwtw04.sys.” – This kind of error message signifies that a kernel-mode driver tried to access pageable memory at a process IRQL that was too high.
2. “SYSTEM_THREAD_EXCEPTION_NOT_HANDLED What failed: Netwtw04.sys” – This error message indicates that the root cause of the error might be incompatible drivers with the operating system. In general, the root cause of the Netwtw04.sys BSOD error might be due to several reasons such as corrupted files, incorrect device driver configuration, malicious programs, outdated drivers, bad drivers, corrupted Windows Registry as well as some damaged or corrupted system files.

Whichever of the two error messages you got, you can try the troubleshooting options given below to fix the “DRIVER IRQL NOT LESS OR EQUAL or SYSTEM THREAD EXCEPTION NOT HANDLED, Netwtw04.sys failed” BSOD error.

Option 1 – Try to rollback your Network driver

If you have updated the driver software as of late and you suddenly got this BSOD error, you might have to roll back the device driver – in other words, switch back to the previous working version. To do that, follow these steps:

• Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
• Next, select the driver entries that are labeled appropriately other than anything in the context of the WAN Miniport.
• Then select each one of them and double-click to open a new mini window.
• After that, make sure that you’re on the Driver tab and if you are not, just navigate to it then click the Roll Back Driver button to switch back to the previous version of your Network adapters.
• Now restart your computer to successfully apply the changes made.

Option 2 – Try to update the Network drivers

If the present Network driver is giving you a headache that is the “DRIVER IRQL NOT LESS OR EQUAL or SYSTEM THREAD EXCEPTION NOT HANDLED, Netwtw04.sys failed” BSOD error, then you need to update the Network drivers. To do so, here’s what you have to do:

• Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
• Then right-click on each one of the Network drivers and update them all.
• Restart your PC and see if it helped in fixing the BSOD error.

Note: If updating the network drivers didn’t help in fixing the problem, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.

Option 3 – Try running the System File Checker Scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the Netwtw04.sys failed BSOD error. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 4 – Run the DISM Tool

The DISM tool is another command-line tool in the Windows operating system that could help users fix various corrupted system files. To use it, follow these steps:

• Open the Command Prompt as admin.
• Then type in this command: DISM /Online /Cleanup-Image /RestoreHealth
• The DISM command you entered will repair the corrupted system image. Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 5 – Run the CHKDSK Utility

Running the CHKDSK utility might also help you resolve the Netwtw04.sys failed BSOD error. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• Wait for the process to be completed and then restart your computer.
