PC will automatically start in one minute loop

cfourkays · 04 Jan 2018

HP Notebook with Windows 10
Owner was doing an adware removal using Malwarebytes Adware Removal Tool.
Something got screwed up and now the PC is in a "PC will automatically start.........."
I managed to get to the Task Manager before the restart and have all marked "Disable"
Booted with a W-10 iso on a flash deive and tried the "Startup Repair" which didn't work.
Frpm a CMD, "bootrec /fixboot Access is denied"
Not sure whether the "diskpart" fix will be needed or work on this.
Looking for an easy way out.

1) Using the windows 10 iso > command prompt > Administrator: X:\windows\system32\cmd.exe
X:sources>
2) type: bcdedit | find "osdevice"
This should display the drive letter for the partition of the affected drive
3) type: sfc /scannow /offbootdir=g:\ /offwindir=g:\windows (change the letter g to the drive letter displayed for the partition in the prior command results)
4) type: g: (change g to the drive letter displayed for the partition in the prior command results)
It should display g:\
5) type: chkdsk /f
It should display:
The type of the file system is NTFS.
Cannot lock current drive.

Chkdsk cannot run because the volume is in use by another
process. Chkdsk may run if this volume is dismounted first.
ALL OPENED HANDLES TO THIS VOLUME WOULD THEN BE INVALID.
Would you like to force a dismount on this volume? (Y/N)

6) type: y

It should display stages and typically ends with failed to transfer logged messages to the event log with status 50.

7) reboot and report results into the thread.

8) The above steps are to repair the operating system and drive file system. If the above did not fix the problem plan steps to fix the boot and/or registry.

Had tried all that.
sfc returned no errors, chkdsk same.
Used the Diskpart fix all the way to the last step cd /d G:\EFI\Microsoft\Boot
Now can't find newly created "G: drive

What did the command: bcdedit | find "osdevice" display for partition?

Where were there steps with cd?
Please list the steps that were made.
If you can use a camera or smart phone camera please post images into the thread.

12) if the above works then create a backup image of your drive using Macrium:
Macrium Software | Macrium Reflect Free

13) if the above fails plan to perform a registry repair

Report into the thread your progress.

Report into the thread the Windows RE steps/command prompt commands that you had made in the prior post.

For the registry repair to succeed the files will be identified and size of the files must be substantial. The dir command will be used to view the files and the sizes.
