How to Resolve Inaccessible Boot Device Error in Windows

0

Inaccessible boot device error in Windows is actually one of the blue-screen of death errors.

Blue screen of deaths or BSODs occurs when a system encounters a fatal hardware or software malfunction. In most of the cases, the system crashes and stops responding, and the only way to get unexpected screen is by rebooting the system.

This is not a new error for Windows, it has been present since the first Windows NT operating system was released in 1993, and even after 20 years, Microsoft is still trying to figure out ways to completely get rid of the error. These errors can occur because of many reasons including – overheating, issues with power supply, device driver corruption or malfunctioning of the hardware.

In fact, most of the times, these errors are caused by device hardware or problems with the software of hardware drivers. The might also be caused because of the low-level software running on the kernel of the operating system.

As we mentioned, blue screen of death completely freezes the screen and the only thing to restart your system. Now, this sudden restart can lead to loss of data that was not saved by the user. If you are using programs like MS Office that has an auto-save option, then you can recover your data, but if your or the application did not save your data, then it’s probably gone.

When the system is crashed, there is also a file called mini-dump created by Windows which has all the information and logs of the error. If you are curious to find out the reason behind the error, then you should definitely check this file. You can find this information in the Windows Event Viewer. A file is created for every application that crashed.

This isn’t always the case, but sometimes newly installed hardware can cause an inaccessible device error on the system. If you have recently installed new hardware, and you only started getting the error after the hardware installation, then you should definitely try running the system without the hardware to see if it was the reason behind the problem
