Enable System Protection on Local Disk (C:) with CMD

Kaktussoft · 16 Jan 2013

check disk is fine. Offline SFC doesn't work. memory is fine. startup repair doesn't find anything. system restore doesn't work. "last good known config" doesn't work. What did you do just before this problem started?

Code:

diskpart
sel vol c
det part
exit

Is it active?

Yes it is active.... + "Status: Healthy"

A day before this problem occured I broke up a Windows update.
Next night I fell a sleep while the netbook was still running.
There were programs running like firefox, skpe, spotify.. mabybe even more.
When I woke up there was this System Repair sreen.
What may have happend is that I cut the electricity from the power socket and the battery was emptied at some point that night.
It may be that since I broke up the Windows update (which was a really studpid idea, but was necessary at the time) I onl ever put the netbook on standbye. So that night it shut down the first time after the update breakup.

I read a lot about people having the same problem after an Windows Update...

Sure, GTXND. Forgive me if I oversimplify but I'll include each step in case you're not familiar with navigating command lines (I was a tech support guy in college 20 years ago; old habits die hard). Also, changing registry files can be VERY DANGEROUS... I would only do it as a last resort before reinstalling Windows 7.

I first booted from the Windows 7 install disc to get to the system recovery console. I then selected Command Line. From there, I had to change from the X: drive to the C: drive by typing "C:". I then typed "cd \windows\system32\config" to get to the registry file directory. By typing "dir" I could see that two of the five hive files (default, sam, security,software, and system) had recent copies with an "rmbak" extension: default.rmbak and software.rmbak. I then executed the following commands:

ren software software.bak
copy software.rmbak software

ren default default.bak
copy default.rmbak default

I would suggest you execute the "ren" then "copy" commands as above for any other hives that have "rmbak" backups with the same date/time stamp. This ensures your registry remains in sync. You can now reboot and see if your computer comes up.

Here is an alternative suggestion if you don't have these "rmbak" files (if the above worked, don't do these steps; these would be a last-last resort before reinstalling Windows 7). From where we left off above type "dir RegBack". See what the time/date stamp is on the hive files there. If recent (use your judgment; mine is a couple days old so I would have probably used it had I not had the rmbak files, as I hadn't installed much in that time), you could do the following to restore that backup registry:

ren default default.bak
ren sam sam.bak
ren security security.bak
ren software software.bak
ren system system.bak
copy RegBack\*.*

Reboot and see what happens. If this worked, you may have to reinstall any software that was installed after the time/date stamps of the files in the RegBack directory.

One final note: I did try to restore to an earlier restore point once I made the above fixes. It kept coming up with an error. Therefore, I suggest creating a new restore point once the computer recovers, just so you have a clean one.

Unfortunatley I was not able to find out how to type in these steps (of the second option):

ren default default.bak
ren sam sam.bak
ren security security.bak
ren software software.bak
ren system system.bak

What exactl does one have to type into the cmd here?

Yes everthing is larger than 10.000. Above DEFAULT it also lists " . " and " . . " these files have no size...

what date/time have these files, so how long ago where they made? Were you able to boot without any problems after that date/time?

Green18 · 17 Jan 2013

The files are from the 5th of january. (07:33 pm) The update was the 9th.

The booting problems showed up th 10th...

Kaktussoft · 17 Jan 2013

Code:

c:
cd  \Windows\System32\config
Now make copy of current registry stuff. Just to be safe. You can revert back to what it was
copy  default   *.mybak
copy  sam  *.mybak
copy  security  *.mybak
copy  system   *.mybak
copy  software *.mybak
dir  *.mybak

All 5 files are copied succesfully? Is so continue

Code:

copy/y  regback\*.*

5 files copied succesfully?

of course say yes for all overwrites! Be sure to answer yes. even better say All. Or user copy/y instead. It doesn't ask for confirmation
