Windows 10: Inaccessible boot device - after windows update (regular update)

Can you provide more info don't know how to back up thru notepad instructions you mentioned. Also can some one confirm if I run mbr command it will not damage the hd where I cannot backup? Also how can I backup if I cannot login to Windows. I am really great ful for everyone's help. I am currently running chkdsk seems it will be the morning when I will have that done.

 

I have record the below posted gif from booted Windows 10 but process is the same from Windows Recovery Environment.

 

Hi two questions, thanks for sending the gif. However if I cannot get into safe mode, then doing what the gif say is not clear how I could do. The only thing that is accessible is command prompt. So is there another way you are suggesting. Earlier someone mentioned to to mbr and fixing it, I wanted to ask will that make my files in accessible since my files are not backed up. Can someone clarify. Thank you.

 

How do you create a restore point? Cannot access anything, can only access command prompt.

Please replace partition letter D: 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.



From Windows Recovery Environment start the Command Prompt.

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

The following command scans integrity of all protected Windows system files and repairs files with problems when possible.

Good news check disk repaired partition errors but are you sure you have executed Chkdsk command for the Windows installed partition?

 

The two images appeared to be nearly identical:
https://drive.google.com/file/d/1SVN...w?usp=drivesdk.
https://drive.google.com/file/d/15Vc...w?usp=drivesdk
It reported : chkdsk made corrections in the volume bitmap and Windows made corrections to the file system.
So this is progress.
Post #16 and #32 indicated if the commands are successful to restoring the operating system you must treat it as a fragile repair and backup files, make a backup image, and make a new restore point.

When available please post the results of the HP UEFI hardware diagnostics.
