Windows reboot after installing an update

Hi,

In last week, some Windows 10 machines made an update (i think the problema is the update) and then after boot, the pc´s are are always reboot. Already tried to restore to a previous restore point, repair boot, etc. But nothing the problema remains.
best regards

Show the output of diskpart list volume, please.
"Inaccesseible boot device" is mostly due to
A  file system corruption, which can be corrected using chkdsk c: /r
B drivers for the hard drive controller that are missing, wrong or corrupted

That's what image backups are for. Don't have any?
Please describe your reboot loop - do you see a bluescreen of death?

Hi,

Backups i have but data only, not entire system image.
When computer starts SO tries to repair boot and then show recovery options.

Yesterday (2/13/2018) was Patch Tuesday and new updates out for Windows 10. On one test machine, make a Windows 10 USB key from the Media Creation Link and see if you can Repair or Reinstall from that (you have data backed up).

Repair installations can only be started from within an already running windows, so that won't work on unbootable systems.
Please quote your bluescreen. (Don't see it? Turn off "automatic restart after crash/failure").

You may need to get the Recovery Media from the Computer Manufacturer and do a fresh install that way.

It would not seem to be a hardware issue based on the initial post.

Ok.

Is your machine based on an Intel CPU or AMD CPU?

Hi,

Intel.

Intel CPU's are working fine at all my clients.

Try as suggested with Vendor Recovery Media.

@author: do you know how to offline-modify the registry? If you do, please deactivate the spectre/meltdown patch like this:
reg add "HKEY_LOCAL_MACHINE\SYSTEM\offline_mapped_branch\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverride /t REG_DWORD /d 3 /f

reg add "HKEY_LOCAL_MACHINE\SYSTEM\offline_mapped_branch\CurrentControlSet\Control\Session Manager\Memory Management" /v FeatureSettingsOverrideMask /t REG_DWORD /d 3 /f

How do you figure that?

Hi,

Diskpart ->listvol

The data partition appears but not the "boot" partition created by Windows 10, is clear. But in a system working well has some files.

You can copy and paste the output here so that we understand. What you share is not understandable.

Hi,

Volume 3 no files and is empty, in a working pc this volume as files and space is occupied.

McKnifeCommented:
Look, If you don't want to share the output, I cannot help you. "empty" is maybe due to the view options in explorer. If system files are hidden from view, it may look empty, although the boot files are there.

Did you know how to execute the command (after mounting the offline registry)? I mean, did you just execute it (and it failed), or did you do it right, the commands succeeded, you dismounted the reg hive and rebooted to no avail?

HI,

I've tried everything at the bios level, repair boot sector, chkdsk, etc., and everything you suggested. I think I'll do a new installation. I cloned the disk so that I could always test with the original installation.

it's a shame how the MS updates "fix" things
i wonder why people keep accepting that as normal...
