Windows 10: Inaccessible Boot Drive after Update?

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.

Looks like System Reserved partition has not been assigned a drive letter. The Volume 3 partition should contain BCD data store file we will assign a drive letter and check to see if BCD data store file exist if it does we will rebuild it.


From Command Prompt type below commands:


Code: Select Volume 3 assign letter=w Exit Dir /A /B w:\boot\bcd[/quote]
Please post a screenshot of above commands outputs.

You have not executed two of the Diskpart commands please execute below commands one at time:


Code: Diskpart List Volume Select Volume 3 Assign letter=w Exit Dir /A /B W:\Boot\Bcd[/quote]

Please post a screenshot of above commands outputs.

 

In the screen shot you can see that the letter W has been assigned. Thank you!

 

what were the outputs of the commands from Inaccessible Boot Drive after Update? - Page 2 - Windows 10 Forums

it looks like C: is the correct drive for your system - however a dir output would also help to verify...
it looks like your bootable drive. the 100mb reserve now assigned W is a normal reservation.

I'm thinking you got same errors on fixboot = denied and rebuildmbr - failed with 0 installs found...

 

Oh my bad i did not notice that can you execute below command and restart your computer.


Code: bcdboot C:\Windows /s w: /f ALL[/quote]

 

Windows found on C, but Y enter gives error.
