Hi , this is my sisters all in one ,. a HP PAV TS22 Dahlia EMEA BTO L6.5

, she said windows did an update ,(she said she had auto updates off .. ) and now i just get a black screen with cursor and an automatic repair loop it seems .
I cannot get it to start in safe mode ,
on the automatic repair screen i get message :

log file :G\Recovery\WindowsRE\Winre.wim\System32\Logfiles\Srt\SrtTrail.txt

I have done chk dsk and get :
failed to transfer logged messages to the event log with status 50

the system diagnostics all check out ok ..
I seem to be going around in circles here , any help appreciated .

a) Are the files backed up?
b) Had you made a backup image?
c) If you needed to perform a clean install is that an option?
d) which version of the HP UEFI diagnostics was run? Was it only memory and RAM? or was it a loop until failure test?

1) Find a flash drive that you can format ( > or = 8 GB)
2) Create a bootable windows 10 iso:
Download Windows 10
Download Windows 10
4) Insert the flash drive into any USB port
5) Find the applicable keyboard key to boot to a device:
List of PC brands with their corresponding hot-keys
6) select external USB hard drive
7) If it is a custom computer open the BIOS and temporarily change boot order so that you can boot using the flash drive.
8) When the iso loads choose language, time, currency, and keyboard, or click next
9) Do not click on install
10) In the left lower corner click "repair your computer"
11) Click troubleshoot
12) attempt system restore: start with the oldest restore point and repeat as necessary to the most recent restore point. If this fails or if there are no restore points advance to the next step.
13) attempt startup repair. If this fails advance to the next step.

14) Click command prompt
This should open: Administrator: X:\Windows\system32\cmd.exe > X:\Sources>

For all of the steps please use a camera or smart phone camera to take pictures and post images into the thread.

24) type: list disk
225) type: list volume
23) type: select disk 0
24) type: list partition
25) type: exit
26) for list volume results look under the column heading Fs for any volume that displayed RAW instead of NTFS
27) type: chkdsk /f /r G: (change G to the drive letter of the volume displaying RAW)
It may display "The first NTFS boot sector is unreadable or corrupt."
This may then convert the RAW volume to NTFS.
28) Type: exit
29) reboot to open the Windows advanced troubleshooting menu > command prompt > Administrator: X:\windows\system32\cmd.exe > X:\Sources>
30) type: bootrec /rebuildbcd
It may display:

Please wait, since this may take a while...

Add installation to boot list? Yes(Y)/No(N)/ALL(A):
31) Type: A
The operation completed successfully.
X:\Windows>
32) Type: exit
33) reboot

If the above steps did not fix the problem advance to the next steps:

34) Open command prompt > Administrator: X:\Windows\system32\cmd.exe > X:\Sources>
35) From steps 20 and 21 results displaying the partition if the drive letter is different than C: please use the displayed drive letter for the next step
36) type: DISM /image:G:\ /cleanup-image /revertpendingactions (change G to the applicable drive letter) ( There is a space between \ / )
37) This should remove the latest update and fix the problem.
38) If this does not fix the problem plan a registry repair.
