BSOD: INACCESSIBLE BOOT DEVICE - Windows 8.1 x64

[wdgordon]

For some time now I have been unable to boot into Windows 8.1. Any attempt to do so results in a BSOD error, citing "INACCESSIBLE_BOOT_DEVICE".

I have spent countless hours reading through various web pages without a clear solution to the problem. One constant, however, seems to be trying to use sfc /scannow, so that it what I am focussing my attention on now.

I am able to access the Windows Recovery Environment after the BSOD error. From here I can access the Recovery Command Prompt.

From here I have attempted to run this command:

sfc /scannow /offwindir=c:\windows /offbootdir=c:\

Every time I attempt the command I receive the following output after a few seconds:

Beginning system scan. This process will take some time.

Windows Resource Protection could not perform the requested operation.

I am seeking help to allow me to deal with this error, so that I can get sfc to work properly.

(I have looked at the BSOD posting instructions, but if I try and run the "SysnativeBSODCollectionApp.exe" I get "The subsystem needed to support the image type is not present".

Similarly, 'perfmon' is not recognized as an internal or external command, operable program or batch file.)

Unfortunately, you will need to rescue any important files via Linux, and then perform a clean install.

Thank you both for your replies. I understand that the response from chkdsk may appear to point towards a hardware issue, but I do not think this is the case for three reasons:

1) Apart from the response I described above, it also indicated that there was 0kb in bad sectors, and seemed to report 'successfully' for each stage of the process.

2) The boot problems happened very soon after I made changes to the system in an effort to speed it up (e.g. stopping a number of windows services, using a 'registry cleaner').

3) I can access files from the offending drive C:\ from my Ubuntu operating system (this one is able to boot) in a different partition.

For these reasons, I suspect the problem is to do with specific system files e.g. the non-installation of a specific update, or a corruption of the registry.

I am reluctant to carry out a system reset unless it is an absolute last resort. I am very grateful for your help and wondered as one last request whether you could point me towards any alternative places on the web or indeed this forum that might have some more experience with these kinds of issues.

As one last piece of information, I should also probably mention that there was one course of action which did result in different behaviour from the BSOD - this was when I replaced the files in my c:\windows\config directory with the files in the c:\windows\config\RegBackup directory. This resulted instead in a black screen which seemed to occassionally flash up with a window for a split second every so often.

The reason why your most likely experiencing BSODs.
