    I need HELP, turned on my home computer last night and when windows started to load it came up with.....

    Window could not start because the following file is missing or corrupt;

    \WINDOWS\SYSEM32\config\system

    You can attempt to repair this file by starting Windows Startup
    Using the original setup CD-ROM
    Select "r" at the first screen to start repair.

    Question, my computer does not look at the CD-ROM on startup, without going into the BIOS and configering, what key can I press to chose what device I want to boot with???
    I am running WINDOWS XP HOME
    Does anyone know what may of cause this problem

    Thanks for any assistance
    Joe

    to run the repair console from the xp disk you will have to enter the bios and set the cd rom as primaty boot device
    the only other way is to download the set of xp boot disks from microsoft one thing you look at is this its not mine but I copied from a web site but I couldnt tell you where

    Hey, jobrla! The next time something like this happens, just restart your computer and hit F8 before the OS begins to load. From the list choose "Last Known Good Configuration", Enter, choose the OS (like Windows XP Professional), Enter and your computer will restart with the config that was shown to be good last. It is a great way to recover from corrupt files and download screw-ups that give your computer a problem!

    The solution from philraz is great, too!

    last known good, doesn't always work, well hardly works, because once people see that error odds our they restart it right away and see if that fixes it. If not, then they are SOL. It only goes back one time, so if there was one reboot than thats it. Better use that CD

    I found this, does this look like and OVER KILL????

    SUMMARY
    This article describes how to recover a Windows XP system that does not start because of corruption in the registry. This procedure does not guarantee full recovery of the system to a previous state; however, you should be able to recover data when you use this procedure.

    Warning Do not use the procedure that is described in this article if your computer has an OEM-installed operating system. The system hive on OEM installations creates passwords and user accounts that did not exist previously. If you use the procedure that is described in this article, you may not be able to log back into the recovery console to restore the original registry hives.

    You can repair a corrupted registry in Windows XP. Corrupted registry files can cause a variety of different error messages. See the Microsoft Knowledge Base for articles about error messages that are related to registry issues.

    This article assumes that typical recovery methods have failed and access to the system is not available except by using Recovery Console. If an Automatic System Recovery (ASR) backup exists, it is the preferred method for recovery. Microsoft recommends that you use the ASR backup before you try the procedure described in this article.

    Note Make sure to replace all five of the registry hives. If you only replace a single hive or two, this can cause potential issues because software and hardware may have settings in multiple locations in the registry.

    If you experience a repetitive occurrence of registry corruption related issues, Microsoft recommends that you obtain and install the hotfix in the following article:
    318159 (http://support.microsoft.com/kb/318159/) Damaged registry repair and recovery in Windows XP
    This update is also included in Windows XP Service Pack 1.
    Back to the top

    MORE INFORMATION
    When you try to start or restart your Windows XP-based computer, you may receive one of the following error messages:
    Windows XP could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SYSTEM
    Windows XP could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SOFTWARE
    Stop: c0000218 {Registry File Failure} The registry cannot load the hive (file): \SystemRoot\System32\Config\SOFTWARE or its log or alternate
    System error: Lsass.exe
    When trying to update a password the return status indicates that the value provided as the current password is not correct.
    The procedure that this article describes uses Recovery Console and System Restore. This article also lists all the required steps in specific order to make sure that the process is fully completed. When you finish this procedure, the system returns to a state very close to the state before the problem occurred. If you have ever run NTBackup and completed a system state backup, you do not have to follow the procedures in parts two and three. You can go to part four.
    Back to the top

    Part one
    In part one, you start the Recovery Console, create a temporary folder, back up the existing registry files to a new location, delete the registry files at their existing location, and then copy the registry files from the repair folder to the System32\Config folder. When you have finished this procedure, a registry is created that you can use to start Windows XP. This registry was created and saved during the initial setup of Windows XP. Therefore any changes and settings that occurred after the Setup program was finished are lost.

    To complete part one, follow these steps: 1. Insert the Windows XP startup disk into the floppy disk drive, or insert the Windows XP CD-ROM into the CD-ROM drive, and then restart the computer.
    Click to select any options that are required to start the computer from the CD-ROM drive if you are prompted to do so.
    2. When the "Welcome to Setup" screen appears, press R to start the Recovery Console.
    3. If you have a dual-boot or multiple-boot computer, select the installation that you want to access from the Recovery Console.
    4. When you are prompted to do so, type the Administrator password. If the administrator password is blank, just press ENTER.
    5. At the Recovery Console command prompt, type the following lines, pressing ENTER after you type 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

    6. Type exit to quit Recovery Console. Your computer will restart.
    Note This procedure assumes that Windows XP is installed to the C:\Windows folder. Make sure to change C:\Windows to the appropriate windows_folder if it is a different location.

    If you have access to another computer, to save time, you can copy the text in step two, and then create a text file called "Regcopy1.txt" (for example). To create this file, run the following command when you start in Recovery Console:
    batch regcopy1.txt
    With the batch command in Recovery Console, you can process all the commands in a text file sequentially. When you use the batch command, you do not have to manually type as many commands.
    Back to the top

    Part two
    To complete the procedure described in this section, you must be logged on as an administrator, or an administrative user (a user who has an account in the Administrators group). If you are using Windows XP Home Edition, you can log on as an administrative user. If you log on as an administrator, you must first start Windows XP Home Edition in Safe mode. To start the Windows XP Home Edition computer in Safe mode, follow these steps.

    Note Print these instructions before you continue. You cannot view these instructions after you restart the computer in Safe Mode. If you use the NTFS file system, also print the instructions from Knowledge Base article KB309531. Step 7 contains a reference to the article. 1. Click Start, click Shut Down (or click Turn Off Computer), click Restart, and then click OK (or click Restart).
    2. Press the F8 key.

    On a computer that is configured to start to multiple operating systems, you can press F8 when you see the Startup menu.
    3. Use the arrow keys to select the appropriate Safe mode option, and then press ENTER.
    4. If you have a dual-boot or multiple-boot system, use the arrow keys to select the installation that you want to access, and then press ENTER.
    In part two, you copy the registry files from their backed up location by using System Restore. This folder is not available in Recovery Console and is generally not visible during typical usage. Before you start this procedure, you must change several settings to make the folder visible: 1. 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}".

    Note You may receive the following error message:
    C:\System Volume Information is not accessible. Access is denied.
    If you receive this message, see the following Microsoft Knowledge Base article to gain access to this folder and continue with the procedure:
    309531 (http://support.microsoft.com/kb/309531/) How to gain access to the System Volume Information folder
    8. 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: • _REGISTRY_USER_.DEFAULT
    • _REGISTRY_MACHINE_SECURITY
    • _REGISTRY_MACHINE_SOFTWARE
    • _REGISTRY_MACHINE_SYSTEM
    • _REGISTRY_MACHINE_SAM

    11. Rename the files in the C:\Windows\Tmp folder 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

    These files are the backed up registry files from System Restore. Because you used the registry file that the Setup program created, this registry does not know that these restore points exist and are available. A new folder is created with a new GUID under System Volume Information and a restore point is created that includes a copy of the registry files that were copied during part one. Therefore, it is important not to use the most current folder, especially if the time stamp on the folder is the same as the current time.

    The current system configuration is not aware of the previous restore points. You must have a previous copy of the registry from a previous restore point to make the previous restore points available again.

    The registry files that were copied to the Tmp folder in the C:\Windows folder are moved to make sure that the files are available under Recovery Console. You must use these files to replace the registry files currently in the C:\Windows\System32\Config folder. By default, Recovery Console has limited folder access and cannot copy files from the System Volume folder.

    Note The procedure described in this section assumes that you are running your computer with the FAT32 file system. For more information about how to access the System Volume Information Folder with the NTFS file system, click the following article number to view the article in the Microsoft Knowledge Base:
    309531 (http://support.microsoft.com/kb/309531/) How to gain access to the System Volume Information folder
    Back to the top

    Part Three
    In part three, you delete the existing registry files, and then copy the System Restore Registry files to the C:\Windows\System32\Config folder: 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
    Note Some of these command lines may be wrapped for readability.
    3. Type exit to quit Recovery Console. Your computer restarts.
    Note This procedure assumes that Windows XP is installed to the C:\Windows folder. Make sure to change C:\Windows to the appropriate windows_folder if it is a different location.

    If you have access to another computer, to save time, you can copy the text in step two, and then create a text file called "Regcopy1.txt" (for example).
    Back to the top

    Part Four
    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.

    It ran through it's boot up..OK
    Stoped with a "DOS" like command prompt c:\windows\..OK
    Typed in my 'md tmp"..OK
    Then I tyed in my first line fallowing the c:\windows\ prompt.

    Sorry about that philraz, I guess I explained it wrong what I was tring to say..

    When I get the windows prompt...
    c:\windows>
    I typed in after it...
    copy c:\windows\system32\config\system c:\windows\tmp\system.bak
    So the whole line reads...
    c:\windows>copy c:\windows\system32\config\system c:\windows\tmp\system.bak
    And it tells me that no files could be found.
    Am I doing something wrong or is it dead??

    Their are some viruses that change the attribites of your system32 folder you could try a bootable virus scan such as fprot on ubcd
    but I think at this point I would start thinking about a format and a reinstall ubcd can be found here

    is your cd romdrive external ?
    have you tried last known good configeration as per my first post ?
    if your drive is internal check your connections
    if your drive is internal it may not be atapi compatable(although this is rare these days) if so download the xp boot disk set from microsoft
