Windows 10: Boot loop after update no safe mode option-repair fails- restore fails

Either BCD data store is damage or boot files are damage lets first try to repair BCD data Store.

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:

Execute below command to point Command Prompt to C: drive.

C:


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.

 

Using Ubuntu to look around I found windows/softwaredistribution/reportingevents.log and see the following KBs:

KB4023057
KB2267602

 

Sorry I was responding while you were. Tried bcdedit export and it fails.

 

Have you executed below command to point Command Prompt to C: drive?

Code: C:[/quote]

 

Yes I did that before executing ecdedit /export.

 

Lets rebuild boot files again.


Can you please post screenshot of below commands:


Code: Diskpart List Volume[/quote]

 

Please execute following command:

Code: bcdboot E:\Windows /s C: /f ALL[/quote] Make sure to execute Exit command to exit Diskpart command before executing bcdboot command.

You may need to replace E: drive letter with Windows OS installed partition drive letter.

Restart your computer.

 

Ok executed it and it reported as successful but restart results in a rapid boot cycle. I shot a video to try and read the message that flashes on the screen. It says "working on updates 75% dont turn off your pc. This may take a while. Your pc will restart several times".

 

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


Please execute below command and reboot your computer to see issue resolves.


Code: DISM /Image:E:\ /Cleanup-Image /RevertPendingActions[/quote] Please replace partition letter E: with Windows installed partition letter. When computer boots into Windows Recovery Environment (WinRE) environment the drive letter assign to Windows partition may not be C: drive letter because Windows 7, 8 , 8.1 and 10 creates a separate system partition when it's installed from scratch. The system partition contains boot files WinRE assigns the system partition the C: drive letter and the Windows installed partition will be assign any other drive letter usually D: drive letter is assign to Windows installed partition. The Bcdedit /enum | find "osdevice" command can be use to find out the drive letter of the Windows installed partition the output of the Bcdedit command is similar to this osdevice partition=D:. The drive letter after partition= is the drive letter of the Windows partition.

 

Fails

 

Restart your computer and try again please.


Please execute following commands:

Code: mkdir E:\scratch DISM /Image:E:\ /Cleanup-Image /RevertPendingActions /scratchdir:E:\Scratch[/quote] Restart your computer.

 

Please execute following commands and restart your computer:


Code: ren E:\windows\SoftwareDistribution SoftwareDistribution.OLD del E:\Windows\WinSxS\pending.xml[/quote]
