Windows 10: Microsoft bootloader seems to be totally missing/destroyed

Hello a friend brought me her laptop and it is refusing to boot in any way.


Facts:


The Volume is bitlocker encrypted -> the key is not available so no mounting in linux or the likes


A bootable USB is not of any help, no option is working NOT EVEN THE COMMAND LINE as in:


bootrec /fixboot returns an error


/scanos does not find anything (0)


bcdedit export fails


recreating the mbr from Linux fails aswell.


Interestingly:


In Linux using fdisk -l 4 partitions show up (all windows partitions) while using diskpart only returns two disks, one being the USB 28GB and the other being the DVD drive. Is there some reason for this? Could the MBR still be intact and could this be another problem?

This update totally destroyed me, which was not totally unexpected.

I have noticed that update issues are fairly common occurrences.

Microsoft must have a site that lists step by step actions that they want you to take when Windows 10 Updates and trashes a system?

Does such a site exist? Where do I go to get help?

Recovering Windows 10 After an Update

Step 1:
sfc /scannow

Step 2:
Dism

Step 3:
etc.. Uninstall Video Drivers and reinstall

 

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.
