A Required Device Isn’t Connected 0xc00000e

Your PC/Device needs to be repaired if it suddenly displays the following error message: Your PC/Device must be repaired. If a required device cannot be connected or accessed (0xc00000f), it may be because the BCD is missing, a system file has been corrupted or a cable has been damaged.

What’s weird is I can’t access the BIOS at all. It just comes up with an “A3” message in the bottom right corner with a black screen. No problem if the SSD is disconnected, but why wouldn’t it access the BIOS?

You can fix this error by using 3 easy methods. If you encounter this message, one of the error codes associated with it is usually 0xC000000e, 0xC000000f, 0xC0000001, 0xC0000225, 0xC0000185…

As in this case, when your computer suddenly displays a blue screen with the following error message: “Your computer/device needs repair. The required device is not connected or not available. Whatever the reason, after a few tries you will probably find that none of the suggestions in the bottom left corner work, and you also cannot start Windows to perform common actions. In this case, you can try the following troubleshooting methods or choose the latest remedy to restore your system and resolve any related issues.

What causes this type of error

6) Follow the instructions on the screen to continue booting from the Windows 10, 8 or 7 USB or DVD bootable media.

As a result of incorrect computer shutdowns (such as a power failure), this BSOD error may occur, and it can usually be caused by incorrect boot configuration data. In Windows operating systems, you may encounter a malfunctioning mirror drive if you use the Windows mirroring feature for fault tolerance.

While Windows System Restore may not be an ideal backup solution for Windows, it can be useful in some situations when you wish only to roll back a Windows Update or undo changes made by a misbehaving application. However, before using Windows System Restore you must ensure that the utility is active and configured correctly.

Accessing and configuring Windows System Restore is not a straightforward task, as the utility itself is somewhat hard to find. Therefore, we will examine how to use System Restore in Windows. Note: The process is very similar for System Restore in Windows 7, Windows 8 and Windows 10.

Several factors may contribute to this error:

  • Hard drive damage.
  • Configurations for booting that are invalid
  • Computer shut down improperly.
