If you encounter a Recovery Error code 0xc000000e, “Your PC needs to be repaired” error on your Windows 10 computer, then it means that there is some hardware failure or an incorrect drive configuration. Apart from the error, it may be accompanied by different error message such as:

• A required device is inaccessible
• The selected entry could not be loaded
• A required device isn’t connected or cannot be accessed
• The selected entry could not be loaded because the application is missing or corrupt
• The boot selection failed because a required device is inaccessible.

As mentioned, the error code 0xc000000e or STATUS_NO_SUCH_DEVICE error indicates that there is a hardware failure or an incorrect drive configuration and to fix it, you have to check your cables as well as check the drive with the diagnostic utility available from the manufacturer of the drive. And if you are using older PATA (IDE) drives, then this kind of error also indicates an incorrect master/subordinate drive configuration. There could be different causes for this error.

Windows has a lot of built-in tools that help you fix tons of system-related issues. One of them is the System File Check which is the tool you can use to conveniently replace potentially corrupted or missing system files with good ones. But what happens when it does not work? Well, you’ve come to the right place as in this post, you will be guided on how you can replace a corrupted single Windows system file manually with a known good copy of the file if the System File Checker scan is not working. When you encounter this issue with the System File Checker, it will be unable to replace the corrupted system files and returns an error message instead. And so to fix and replace corrupted system files in your Windows 10 computer without the help of System File Checker, you can refer to the instructions provided below. Step 1: First, you need to open the log files listed below and identify which particular file has been corrupted:

• %userprofile%Desktopsfcdetails.txt
• Log %WinDir%LogsCBSCBS.log

Step 2: You will see all the details on the given log files. Once you find out the name and the path of the file, you have to take ownership of this corrupted system file. Step 3: To take ownership of the corrupted file, you need to pull up Command Prompt by tapping Win + R keys on your keyboard and then type “cmd” and tap Enter. Step 4: After opening Command Prompt, type and enter the command below to execute it:

takeown /f FileNameAndPath

Note: In the given command, “FileNameAndPath” represents the name and the path of the corrupted file. For instance, the corrupted file is named “wuapi.dll”, then you need to type “takeown /f C:/Windows/System32/wuapi.dll” Step 5: Next, you need to grant administrators full access & control to the corrupted file and you can do that via Command Prompt again. Step 6: In the elevated Command Prompt, type and enter the following command to execute it:

icacls FileNameAndPath /GRANT ADMINISTRATORS:F

Note: We’re going to use the wuapi.dll again as an example. So the command should be like this: icacls “C:/Windows/System32/wuapi.dll /grant administrators: F”. Step 7: Now all that’s left to do is replace the corrupted system file with a good copy from a trusted source. Once you have a copy, open an elevated Command Prompt again and execute the following command:

copy NewFileLocation FileNameAndPath

Note: In the command given above, the “NewFileLocation” is the location where you have saved the copy of the file. For instance, if you’ve saved it on your desktop, this is how it should look: “copy C:/Users/<username>/Desktop/wuapi.dll C:/windows/system32/wuapi.dll”

In the past, CDs, DVDs, and floppy drivers used to be the primary sources of external storage for many users – that is until the USB storage devices took over. These days, a lot of devices no longer have a built-in CD or DVD writer or reader as it contributes to the thickness of the device. On the other hand, there are still various devices that still come with a built-in CD or DVD writer or reader. However, recently, users who still use CD or DVD on their devices reported a problem where the CD or DVD icon is not visible in the File Explorer as well as in “This PC” or the My Computer page. The cause of this issue is still unknown at the time of writing, but there are still some potential fixes you can try to fix it. You can try to update or roll back the device drivers or apply some tweaks in the Registry Editor. For more details, refer to the given options below.

Option 1 – Try to update or rollback device drivers

The first thing you can try to fix the missing CD or DVD icon is to either update or roll back the device drivers.

  • Standard Dual Channel PCI IDE Controller.
• Now, right-click on each one of the listed drivers and update them all. You could also try to roll them back to their previous versions.

Note: You can also directly download the relevant drivers of your computer from the manufacturers’ website. So if you have an SSD, the issue might be due to an old storage driver.

Option 2 – Try to use the Registry Editor

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and then tap Enter to open the Registry Editor.

• After that, look for the DWORD values named “UpperFilters” and “LowerFilters”.
• Right-click on each one of these DWORD values and select Delete.
• Now restart your computer and see if it fixes the problem.

Option 3 – Try creating a new Registry entry

There is another option you can try in the Windows Registry to fix the missing icon of the CD/DVD. You can try adding a new entry. How? Refer to these steps:

• Tap the Win ­+ R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
• After that, navigate to this registry path: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesatapi
• From there, right-click on “ATAPI” and select New > Key.
• After that, name it is “Controller0” and right-click on the sub-key and then select New > DWORD (32-bit) Value.
