Windows 10: Corrupted boot sector after latest windows updated

Last Friday I selected the 'update and shut down' option and left for a few days. Next time I tried to boot up, got the blue screen of death. Unable to repair, unable to restore. Looking through the srttrail log, I found "recently serviced boot binary is corrupt".


Unable to start in any Safe Mode option, getting error code 0xc000021a no matter what I try.


Ran chddsk /r, had some problems, ran again and eventually completed successfully with a few bad clusters marked.


Tried many things that were found in various posts:

- bootrec /fixmbr - ok

- bootrec /fixboot - keep getting "access denied"

- bootrec /scanos - keep seeing 0 windows installations


Tried renaming/removing bcd file, but was unable to find any bcd file in any boot directory (maybe this is an obsolete process?)


bcdedit displays Boot Manager and Boot Loader attributes, pointing to partition 'C'.


Eventually found command bootsect /nt60 ALL which finally allowed the **** /fixboot command to run, but bootrec /rebuildbcd still finds 0 windows installations, and does not run.


Tried bcdboot c:\Windows, said it completed successfully but no difference.


How can I rebuild my boot record so I recover from this issue? Spent a lot of time on this so far, very frustrating ...


From the WindowsUpdate log it looks like version 20190602.204143.841 is the version that was applied.


I'm running on an older Dell XPS 8700

Windows 10 Boot Sector corrupted and unbootable after update kB3163018 & Kb3149135 code 0xC0000001

Windows 10 Boot Sector corrupted and unbootable after update kB3163018 & Kb3149135 code 0xC0000001.

I can restore a workable image from Macrium Reflect from before the update, but as soon as I restore the update slams in and corrupts the boot sector.

A) how do I stop the automatic update so I can try and address the issues

B) How can I debug the problem causing the updates to corrupt the windows 10 boot sector and how can I fix the issue.

Since my PC is in a catch 22 loop of restore, update & corrupt please send suggestion/answers to my work email address

windows 10 "the first ntfs boot sector is unreadable or corrupt raw"

Hi,

Corrupted boot system files is one of the possible reasons why you are having an error message, the first NTFS boot sector is unreadable or corrupt, when you run the Check disk (Chkdsk) tool. Since you already tried using DiskPart and it shows that the partition
is RAW, we suggest that you perform a clean install of Windows 10. You can follow the steps in this

Forum Article that was provided by Andre Da Costa to perform a clean install or reinstall of Windows 10.

Should you need further assistance, don't hesitate to get back to us.

Hi,

Thank you for providing us with the response to our questions.

I suggest you to run Check disk and check if it helps. Remove your external Hard drive and perform the steps on your system:

Check disk is a utility that can check your hard drive for corrupted segments and fix them. You can refer to these steps to run the Check disk utility:

• 
  Press Windows key + X, select “Command promt (Admin)”.
  
• 
  In the command prompt window, type
  “chkdsk/r” and press Enter.
  
• 
  Press “Y” when it asks if you want to check disk to run when the computer boots the next time.
  
• 
  Restart the computer for Check disk to detect and repair any corrupted sectors in your hard drive.
  

Important: While performing Error-checking or ChkDsk on the hard drive, if any bad sectors are found and when attempting to repair that sector, the
data available on that sector might be lost.

Please let us know if you face any issues with Windows.

Thank you.
