Windows 10: INACCESSIBLE BOOT DEVICE on startup

Hello,
after regular update, my PC will not start, all I get is INACCESSIBLE BOOT DEVICE Error and DSOD. I can still access windows advanced troubleshooting menu > command prompt and I have been trying and trying. I have also managed to update the BIOS but no luck. I have followed tutorial from zbook, post 2. Since in step 14 I had osdevice partition=F, I typed chkdsk /r F: in step 19 - is it correct? But I´m not sure what to type in step 20 instead of G...?
Can you please help me?

OK I guessed and typed: sfc /scannow /offbootdir=F:\ /offwindir=F:\windows - seems to be running now:

And I cannot continue, because after typing bootrec /fixboot, I see Access is denied. *Sad

 

And when I power on, it is still the sam BSOD, starting in Safe Mode not possible either, nor the restore point is working, nothing so far...this is mad *Sick

 

The problem with inaccessible boot device in January was related to Spectre and Malestrom.
Microsoft responded with Windows updates that had unexpected problems:
inaccessible boot device
problems with USB ports

Thank you, first I removed this one:
dism.exe /image:c:\ /remove-package /packagenameackage_for_RollupFix~31bf3856ad364e35~amd64~~16299.248.1.17 and it did not help, the previous package is not installed...
Any idea what can I do please?

Fix: bootrec /fixboot access denied in Windows 10

If the above fails there is another option

 

Thank you for your advice, I have spent almost 24hrs with it and I have finally decided to run a fresh install using the USB. I hope that it will go well. I have been trying almost every possible solution and nothing was working...
