Repair - \windows\system32\ config\system
Sunday, August 20, 2006
windows could not start because the following file is missing or corrupt: \windows\system32\config\system
This is a nasty little greeting that has appeared on my Windows XP machine a couple of time recently, it's also popped up at work and on a friends computer.
Thankfully, it has a fairly simple solution. During the last 4 times of fixing it, I have streamlined the solution which cuts out a few unnecesary steps I've seen mentioned in the first few articles I looked to for help.
The Solution:
1. Turn your computer off
2. Insert your Windows XP CD and reboot from the CD drive
To boot from CD, press DEL on startup and enter into the system BIOS setup and select your CD drive as the first boot drive, press F10 to save your settings and exit
Your computer will reboot from the XP disc
3. Press 'R' when offered the option of using the Windows Recovery Console
(Note: there are lots of articles telling you NOT to do it this way, but from my recent experience this is the quickest and easiest way.)
4. The Recovery Console
At the prompt type the following:
C:\WINDOWS >cd system32\
this changes the current directory to C:\Windows\System32
ren config configold
This renames the config folder to configold
mkdir config
this makes a new directory called config
cd config
changes the current directory to c:\Windows\System32\Config
then type the following lines pressing enter after each one
copy c:\windows\repair\system
[EDIT added 17/04/2007] If the system file is the only one missing / corrupted, it may not be necessary to continue with the other 4 lines of code. The reason they are here is that the second tme it happened to me, when I rebooted after replacing the system file, it then asked me for the next, then the next etc.[end EDIT]
copy c:\windows\repair\software
copy c:\windows\repair\sam
[EDIT added 17/04/2007] Be warned, replacing the SAM file can overwrite your current windows password - if you have changed your password since installing windows you may not be able to get access to your computer.
A safe way of doing this is to replace all other files but ONLY replace the SAM file if you get an error message on startup saying it is missing or corrupted.
A few people on here have had this issue and I apologise for not realising this was possible.[end EDIT]
copy c:\windows\repair\security
copy c:windows\repair\default
after each line it should say:
1 file copied
type:
exit
5. Reboot
(you will have to go back into the BIOS setup and change the boot drive back from CD to your primary Hard Disk)
When your computer boots, it will probably run CHKDSK and show lots of orphaned files which it will automatically repair [EDIT added 17/04/2007] It would make sense to run check disk after your first successful reboot.[end EDIT]
Windows should boot normally and everything should be fine!
If this article has helped you out of a sticky spot, please feel free to make a donation
ren config configold
mkdir config
cd system32\config
It then says the folder doesn't exist.
Even though after retyping the first 2 lines it tells him they already exist.
Jason
cd system32\config
should be replaced with
cd config
I will edit the post to reflect the change
After I type copy c:\windows\repair\system
I get THE SYSTEM CANNOT FIND THE FILE SPECIFIED...
But it can copy all the others e.g. software,sam,security etc..
I tried spelling errors but to no avail
Any way around it?
Thanks
Brian.
if anyone has a solution please email me at p_guenther
thanks in advance
First thing to do is make sure that
the system file is there, try:
dir c:\windows\repair
If it's not, the easiest option is to copy them from a friend and pop them on a USB drive or CD then access it on there.
Let me know how you go

Any help will be much appreciated as I'm completely locked out of my PC because of this.
I just changed directory to C:\windows\repair and found a file called repair.bak.
From the system32\config folder I typed "copy C:\windows\repair\system.bak",
then renamed the file to "system" with "ren system.bak system".
Computer booted after that.
You'll probably have to change some of your vga settings and such back to normal, but it works.
Thanks!!!
I included all the files that you could copy as on my second attempt at replacing the SYSTEM file, I rebooted only to find the SOFTWARE file was corrupted as well.
Replacing the SAM file is you choice, it may be unecessary and worst comes to the worst, when you reboot you have to complete the process again.
i try to select every one and so far all it does is reboot and goes to the safe mode options page over again and again
2 x2.8 Ghz CPU
Asrock 775-i65
Motherboard) are brand new is this a hardware fault any help would be great because im lost!! could you plz e-mail me at d.dw.worgan
Just follow the instructions in the main article, the system.bak idea might work for some but obviously not you tonight.
Boot from windows CD and take it from there.
If you're still stuck, email me using any email link on the rest of the site and I'm happy to help.
We'll get that schoolwork back for you!

i've tried everything i know, but with no luck.
then i tried your tips, and...just in some seconds, his computer returned to normal!
thanks for your help!

You will need to get hold of a WinXP disc.
To fix this problem, borrowing one is fine, it doesn't have to your original disc but it does have to be the same version i.e. WinXp Home or WinXP Professional.

Oh, BartsPE is just as effective as Recovery Console, shouldnt have anything to due with the problem you have.
Thanks

Firstly, If the system file doesn't exist in the repair folder you can get a copy from the Win Xp cd.
Make sure it it the same edition as your Windows Xp i.e. Home or Professional.
I'm pretty sure it needs to come off an XP CD - do not steal it from other computers - inevitably they have different hardware configurations and i think this might be why your blue screens are appearing
THANK YOU SOO MUCH
you have been bookmarked :D
I have tried all the procedures you mentioned above about renaming the configold folder and copying all the files. However after I rebooted and changed my first boot device to my Hard drive, all I get is a gray progress bar at the bottom of a black screen, that reboots the computer automaticaly when it is at 100%. It starts over again after it reboots on its own.(grey progress bar). The progress bar at the bottomw of the screen kinda looks like this:
|||||||||||||||||||||||||||||||||||
is there anything else I can do? Please any suggestion would be greatly appreciated. Thanks in advance.
i followed ur steps and it worked perfectly, after i restarted my computer the user name came up as Administrator, and i dont seem to remember that password. did it restore my computer?can i still get my old settings back?like my folders and stuff.
boot to safe mode then.....
Start Windows Explorer.
2. On the Tools menu, click Folder options.
3. Click the View tab.
4. Under Hidden files and folders, click to select Show hidden files and folders, and then click to clear the Hide protected operating system files (Recommended) check box.
5. Click Yes when the dialog box that confirms that you want to display these files appears.
6. Double-click the drive where you installed Windows XP to display a list of the folders. If is important to click the correct drive.
7. Open the System Volume Information folder. This folder is unavailable and appears dimmed because it is set as a super-hidden folder.
Note This folder contains one or more _restore {GUID} folders such as "_restore{87BD3667-3246-476B-923F-F86E30B3E7F8}".
then
Open a folder that was not created at the current time. You may have to click Details on the View menu to see when these folders were created. There may be one or more folders starting with "RPx under this folder. These are restore points.
9. Open one of these folders to locate a Snapshot subfolder. The following path is an example of a folder path to the Snapshot folder:
C:\System Volume Information\_restore{D86480E3-73EF-47BC-A0EB-A81BE6EE3ED8}\RP1\Snapshot
10. From the Snapshot folder, copy the following files to the C:\Windows\Tmp folder: ââ¬Â¢ _REGISTRY_USER_.DEFAULT
ââ¬Â¢ _REGISTRY_MACHINE_SECURITY
ââ¬Â¢ _REGISTRY_MACHINE_SOFTWARE
ââ¬Â¢ _REGISTRY_MACHINE_SYSTEM
ââ¬Â¢ _REGISTRY_MACHINE_SAM
11. Rename the files in the C:\Windows\Tmp folder as follows: ââ¬Â¢ Rename _REGISTRY_USER_.DEFAULT to DEFAULT
ââ¬Â¢ Rename _REGISTRY_MACHINE_SECURITY to SECURITY
ââ¬Â¢ Rename _REGISTRY_MACHINE_SOFTWARE to SOFTWARE
ââ¬Â¢ Rename _REGISTRY_MACHINE_SYSTEM to SYSTEM
ââ¬Â¢ Rename _REGISTRY_MACHINE_SAM to SAM
1. Start Recovery Console.
2. At the command prompt, type the following lines, pressing ENTER after you type each line:
del c:\windows\system32\config\sam
del c:\windows\system32\config\security
del c:\windows\system32\config\software
del c:\windows\system32\config\default
del c:\windows\system32\config\system
copy c:\windows\tmp\software c:\windows\system32\config\software
copy c:\windows\tmp\system c:\windows\system32\config\system
copy c:\windows\tmp\sam c:\windows\system32\config\sam
copy c:\windows\tmp\security c:\windows\system32\config\security
copy c:\windows\tmp\default c:\windows\system32\config\default
then if your still missing stuff.
1. Click Start, and then click All Programs.
2. Click Accessories, and then click System Tools.
3. Click System Restore, and then click Restore to a previous RestorePoint.
Wasn't as lucky as you! Since my original disk was in chinese (bought laptop from China), I lost all my files after inserting the disk and pressing 'R'. How do I recover my lost files if possible?
Please email me at casse_boss
I'm dealing with the same startup error with Windows 2000. I've booted with 4 floppys and got to the recovery console, but the cursors at "c:\winnt" and it won't let me type "C:\WINDOWS >cd system32\". It keeps saying invalid command.
I'm new at the dos thing, any help? And should I be typing anything different since I'm using a floppy and not a cd?
Thanks in advance, Jeff "jeffc2112"

In my case I know what has caused the problem but I don't know what to do about it!
The original instructions say that you don't have to copy all the registry hives from REPAIR, but only the ones needed to replace the ones that have been corrupted. So without giving the matter any thought I just went ahead and copied SYSTEM (the one that was reported as missing) and rebooted!
Oh dear! I now realise that the CONFIG directory has only this one registry hive in it, because the instructions didn't tell me to copy all the other ones from CONFIGOLD!!! So naturally enough, on rebooting things look promising at first .... but then the black screen appears when the remaining registry hives are not found.
The problem now is that on going back to Recovery Console in order to fix the problem, the password doesn't work because the SAM hive is not there! If only I could get past this I am sure everything would now be fine!
Is there a default password for use under these circumstances?
Any help would be most appreciated!

did u ever find a solution? thanks

When I put my XP Disc in, it will not read the disc. I have tried other disc also. Is there another way to fix the problem with out using the disc.
The CD drive looks as if it is working properly, and says it is working properly.
I have tried everything many times over and I just keep getting the same screen and same message (windows could not start because the following file is missing or corrupt \windows\system32\config\system)
Best wishes

First, I am a fan and I appreciate all the help you provide for others and myself.Now that I have showed my appreciation perhaps can can get some additional help from Webecho. My computer suffers from system32/ config/system and I am trying to repair it as you instruct, but I am stuck at the AMIBIOS setup window. You mention that one must select the CD drive as the first boost;however, this is where I am stuck. I don't have that option (or at least I don't think I do), but I have the following selections: (1)Standard CMOS Setup, (2)Advenced Setup, (3)Power Management Setup, (4)PCI/Plug and Play Setup, (5)Load Optimal Settings, (6)Load Best Performance Setings, (7) Features Setup, (8)CPU PnP Setup, (9)Hardware Monitor, (10)Change Password, And (11)Exit. Is any of these the one I am suppose to selcet or am I suppose to find the CD drive selection (if so, how do I get the CD drive selection active).Please help a fan in need,Thank you!
I have a CD copy of Windows XP giving to me by an associate, can I still use it to repair a System32/Cinfig/System problem on my desktop or do I need an original CD of Window XP(Operating System)? Please Help!

It wont boot into windows...
with the message"...missing file or corrupt: \WINDOWS\SYSTEM32\CONFIG\SYSTEM
You can attempt to fix..."
I can boot into MAC system and insert the original XP Pro CD and choose a boot from that however after attempting that I get the same windows, I cant find a way into the screen that allow 'r' (repair) so cant get past setpe one in your guide.
I have tried pressing teh DELETE key (on the MAC keyboard) on an attempted boot into both the CD and windows Hard drive to no avail.
Any suggestions much appreciated, otherwise I am stuck with a renistall on XP from MAC, probably with the loss of all data and programs...Ouch!
Thanks a lot in advance.
