Default file missing/corrupt

when I start up my compuer, when it gets to where it would normal have the windows logo while its loading, instead I get this error message


Windows could not start because the following file is missing or corrupt:
/Windows/system32/config/system

You can attempt to repair this file by starting windows setup using the original setup CD-Rom
select 'r' at the first screen to start repair.


But when I put in the CD, I get the same error message. I tried taking out the drive with the OS on it and using what is normally the slave as a master, but it just tells me "OS not detected".

Do you have your BIOS setup to boot from CD? That would be my guess as to why you cant load from the XP CD.

1/ Insert the Windows XP CD into the CD-ROM and restart your pc
2/ At the ‘Welcome to Setup’ screen press R to start the recovery Console
3/ The Recovery Console will now open and the list of Windows installations will appear

4/ As you only have one installation on your PC you need to press the number which is relevant to your installations location. This, obviously will typically be 1

5/ When requested type in your Administrator password. If you haven’t set an administrator password, then simply press Enter
6/ The Recovery Console command prompt window will now appear
7/ At the Command prompt type the following, pressing Enter after you have typed each line.
md tmp
copy c:\windows\system32\config\system c:\windows\tmp\system.bak
copy c:\windows\system32\config\software c:\windows\tmp\software.bak
copy c:\windows\system32\config\sam c:\windows\tmp\sam.bak
copy c:\windows\system32\config\security c:\windows\tmp\security.bak
copy c:\windows\system32\config\default c:\windows\tmp\default.bak

delete c:\windows\system32\config\system
delete c:\windows\system32\config\software
delete c:\windows\system32\config\sam
delete c:\windows\system32\config\security
delete c:\windows\system32\config\default

copy c:\windows\repair\system c:\windows\system32\config\system
copy c:\windows\repair\software c:\windows\system32\config\software
copy c:\windows\repair\sam c:\windows\system32\config\sam
copy c:\windows\repair\security c:\windows\system32\config\security
copy c:\windows\repair\default c:\windows\system32\config\default
8/ Now type Exit to exit the recovery console
9/ Finally restart your pc
10/ When the PC restarts log on as Administrator. if you are using Windows XP Home you can only log on as Administrator via Safe Mode.

11/ The next step is to copy the registry files from their backed up location using system restore. However, before you can begin you need to set the folder options in Windows Explorer to Show Hidden Files and Folders

12/ Open Windows Explorer

13/ Click the Tools option on the main toolbar

14/ From the drop down menu click on Folder options

15/ In the Folder options window click the View tab

16/ Look down the file list until you come to a section marked Hidden Files and Folders

17/ Click on the Radio button on the left of the option Show hidden Files and Folders to enable this option

18/ Next move down two lines and remove the check mark next to the option Hide Protected operating system files (Recommended)

19/ You will receive a message informing you that editing or deleting these files could cause damage to your system. Click Yes to confirm that you want to display these files.

20/ From the folder/directory list in Windows explorer click on the drive where you installed Windows XP

21/ Open the System Volume Information folder (The folder appears dimmed) If you receive a System volume Information is not accessible. access denied Error message see Microsoft Knowledgebase Article 309531

22/ Inside you will find one or more folders that look something like this "_restore{87BD3667-3246-476B-923F-F86E30B3E7F8}".

23/ If the folders are displayed as icons or thumbnails click the View option on the main toolbar and click on Details to give a more detailed view of the files

24/ Select a file that was not created at the current time and that starts with RPx (these are Restore Points)

25/ Open one of these folders and look for a Snapshot folder - for example: C:\System Volume Information\_restore{D86480E3-73EF-47BC-A0EB-A81BE6EE3ED8}\RP1\Snapshot

26/ From this snapshot folder copy the following files to C:\Windows\tmp folder

_REGISTRY_USER_.DEFAULT

_REGISTRY_MACHINE_SECURITY

_REGISTRY_MACHINE_SOFTWARE

_REGISTRY_MACHINE_SYSTEM

_REGISTRY_MACHINE_SAM

27/ Now rename the files as follows:

Rename _REGISTRY_USER_.DEFAULT to DEFAULT

Rename _REGISTRY_MACHINE_SECURITY to SECURITY

Rename _REGISTRY_MACHINE_SOFTWARE to SOFTWARE

Rename _REGISTRY_MACHINE_SYSTEM to SYSTEM

Rename _REGISTRY_MACHINE_SAM to SAM



Step Three


28/ You now have to delete the existing registry files and copy the system restore registry files to the C:\Windows\System32\Config folder: You can do this either by using Recovery Console or (if you file system is FAT32) by using a Windows 98 Start Up Disk) Whichever method you use you will be presented with a command prompt. At the command prompt type the following, remembering to press Enter after you have typed 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

29/ Now type the following, pressing Enter after you have typed each line:

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

30/ Finally Exit Recovery Console and Restart your PC (If you are using the Windows 98 startup disk simply press CTRL-ALT-DEL to restart your pc

Step Four
31/ After your PC has rebooted click the Start button followed by All Programs

32/ From the All Programs menu click Accessories

33/ From the Accessories drop down menu click on System Restore

34/ From the System Restore window click on the Restore to a Previous Restore Point option and restore your pc to a previous restore point

Well I ordered the computer from ibuypower and it came with this CD. After a while my mobo got messed up so I got a new mobo, video card, RAM, CPU, but same HD. The CD I am using is the original one, could that be the problem?

1/ Restart your PC
2/ Keep tapping the F8 Button until a menu appears
3/ When the menu appears use the UP and DOWN arrow keys to select the ‘Last known good configuration’ option.
4/ Once selected press Enter
5/ Your PC should now reinstall the ‘last known good configuration file’
6/ Restart your PC and see if the problem has been solved

If you have a new mobo, Vid, RAM, CPU the only option you have is to format and fresh install. That will be the only way to stop errors.

well the 1st problem is the missing/corrupt file.

the 2nd problem is that I can't start the recovery thing from the XP CD.


I tried the last known configuration thing, and I get the same error

damn this sucks, right before a 3-day weekend
