Inaccessible Boot Drive after Update?

have to use the DISM via CMD in troubleshooting to find the most recent KB installed....
mine was a C++ but was able to roll back a few days on that one only... ~10/11th jan 2018 - still never checked which KB though and paused updates until mid Feb.

our AV is Vipre 10 Endpoint - which is compatible with all new cpu patches... supposedly.
figure ms should just use google approach to fixing their packages.. think NIX systems are using the opensource fix vs the MS performance impacting fix, but we'll see.

beyond that I have a lot of different packages loaded on this system - could be any one of them installed that "could" conflict with an update... but inaccessible boot - and non of the fixboot commands were fully working, nice work MS...

My computer also with an SSD is getting "The boot config data file doesn't contain valid information for an operating system"

File: \BCD
Error Code: 0xc0000098

Startup repair failed
Manual BCD repair failed

Tried the guaranteed Windows Recovery Disks which also failed.

Is this related. Can you point me in the right direction?

Recovery says I need to select an OS first...

Please boot your computer with Windows Installation Media and from Windows Recovery Environment start the Command Prompt.

Please type below commands into Command Prompt and press Enter key.

Following commands will repair Master Boot Record (MBR), Boot Sector and BCD Store.

Code:

Bootrec /FixMbr

Bootrec  /FixBoot

Bootrec  /RebuildBcd

Restart your computer.


If above commands has not resolved the issue follow below instructions:


Since the BCD store exists and lists a Windows installation, you'll first have to "remove" it manually and then try to rebuild it again. At the prompt, execute the bcdedit command as shown and then press Enter:

bcdedit /export c:\bcdbackup

The bcdedit command is used here to export the BCD store as a file: bcdbackup. There's no need to specify a file extension.

The command should return the following on screen:

The operation completed successfully.

Meaning the BCD export worked as expected.

At this point, you need to adjust several file attributes for the BCD store so you can manipulate it. At the prompt, execute the attrib command exactly like this:

attrib c:\boot\bcd -h -r -s

What you just did with the attrib command was remove the hidden, read-only, and system attributes from the file bcd. Those attributes restricted the actions you could take on the file. Now that they're gone, you can manipulate the file more freely - specifically, rename it.

To rename the BCD store, execute the ren command as shown:

ren c:\boot\bcd bcd.old

Now that the BCD store is renamed, you should now be able to successfully rebuild it.

Try rebuilding the BCD again by executing the following, followed by Enter:

bootrec /rebuildbcd

Restart your computer after rebuilding the BCD store.

you able to get into recovery trouble shooting options and get into cmd prompt?

need to locate which drive has BCD data on it...

in my case it was e:\

although a full rebuild of the BCD Still didn't help - it was able to finally find the OS ... normal bcd rebuild didn't find os at all..

my particular resolution I lucked out with a restore option that was available...
maybe for that error code this video - but doubtful
How to Fix Error Code 0xc0000098 in Windows 10 WORKS 100% - YouTube

I can get to CMD with and without USB bootable.

With bootable: tried the video with error "The store export operation has failed. The requested system device cannot be found."

x:\ gives windows DIR

tried on x:\ and c:\

CMD without bootable I get to -h -r -s before I get stuck.

Which drive has your windows directory and files in it..
X: is a ram drive created by the recovery ...
you need to find which drive has your os on it..

basically
type: b:
dir

then c:
dir
basically looking for the directory structure that is correct... should have
?\users\<yourusername\ under users...

x: doesn't have what is needed... for some reason the mapping of the drive is something out of the ordinary...

could be e / f /g depends on how windows choose to setup for some reason and number of disks in the system and partitions on the drive... kinda dumb but mine was found under e:

Please execute below commands from Command Prompt and post a screenshot of the commands output:


Type diskpart and press Enter.
Type list volume and press Enter.

C:\ finding windows but won't complete BCD repair.
