'Fatal error C0000034' on boot after Service Pack 1 for 64-bit systems install

Question

Hi there,

I installed Windows 7 Service Pack 1 for 64-bit system on my laptop after it appeared on Windows Update. The install seemed to go alright, however, when I restarted the computer at the prompt of Windows Update, it gets as far as the Starting Windows screen, before throwing 'Fatal Error C0000034 applying update operation 282 of 114599 (_00000...)'

At this point, the startup sequence hangs and gos no further. I restarted again by switching off at the mains, and this time was prompted to run Startup Repair. I tried this, however the Startup Repair program hung (I left it for several hours with apparently no effect). I then proceeded to try the following things:

-Boot in Safe Mode

This led to the startup to hang at the 'Loaded: CLASSPNP.SYS', 'Please wait...' stage. Again, left for several hours, no progress.

• Run the recovery CD to restore from a System Restore point.

The program hung at the restoring system stage - again, left for several hours, nothing happens.

• On advice from google, I tried using the recovery console to run DISM /image:D:\ /cleanup-image /revertpendingactions (I should mention that the recovery CD seems to think my windows install is now at D rather than C)

This led to an error attached at http://cid-78779374d6b6f1f3.office.live.com/self.aspx/.Public/dism.log

• Booting from last known good configuration

This just resulted in the same error as when I boot it normally

I haven't tried a complete system reinstall, as ideally I'd like to keep my files...

Any help would be greatly appreciated.

Sam

Okay, after much searching of Google, I found an answer that worked for me, my computer is now fixed without having to reinstall the OS. Solution courtesy of Aran, was found athttp://social.technet.microsoft.com/Forums/en-US/itprovistasp/thread/4491fe25-be44-430e-a384-fb58c5da5ad0/

It essentially involves doing a manual system restore.

• Open the recovery console
• Change working directory to whatever the root folder of the Windows install is (might be D: or some other letter for some people):

cd /d C:\windows\system32\config

Rename the following files by typing the following:

ren default default.oldren sam sam.oldren security security.oldren software software.oldren system system.old

• Change the working directory:

cd regback

• Copy the files from this directory to the previous directory as follows:

copy default c:\windows\system32\configcopy sam c:\windows\system32\configcopy security c:\windows\system32\configcopy software c:\windows\system32\configcopy system c:\windows\system32\config

• Having done this, I restarted my computer, and it booted all the way with no errors. However, it seemed somewhat unstable, so I booted into Safe Mode and ran CHKDSK (chkdsk /B) and conducted a normal system restore to before the service pack install using the normal method. To fix remaining problems, I ran sfc /scannow. My computer now seems to be running as well as ever.

Hope this helps,

Sam

uh, not nice, I was very worried and I am  even more worried now, I have exactly same problem as above, same error code etc, however, I even cant get into safe mode, all i get when pressing f8 is that I can use normal recovery or option with repair , however both failed constantly.

dont want to sound pathetic but my life is on that PC, I just transfered very important docs and files on it and was about to transfer some more before making usual back up, I use it only for couple of days and erased all from the old pc, I really hope something will be possible to do in this matter so that I get my stuff back asap

Win7 Ultimate x64

Wow - Thank you.  Have been working on this all day.  Finally determined that my system was installed on my D drive, so was able to do all of the above steps on my D drive and I can now boot normally into my Windows 7 system.  Spent much time trying the above steps on my X drive(seems to be labeled my "Boot" drive?  Also tried unsuccessfuly to do the above steps on my C drive.  Someone said they found their solution in finding their operating system on a different drive.  Wasn't sure how many drives I had because you cant see the drives at the command prompt.  So i just tried changing the drive from a to whatever and found that I also had a drive D on this computer.  So I then tried the above steps on the Drive D and WHAM!   it all worked.  I had initially found my files on the X drive but the system would not let me rename the files as suggested above.  My files on the D drive did let me rename the files and so SUCCESS!!!! was also able to do the remaining steps and I am back up and running!  Thank you.

You are a lifesaver!  I was dreading the hours I would spend restoring my computer back to it's former self. Your advice had me back up in 20 minutes!  Now I wonder: should I retry the service pack update or consider it a lesson learned and leave everything alone?
