• Default file not found - necessary to recover from a corrupt registry XP

  I'm trying to follow the instructions to fix the "windows\system32\config\system missing or damaged file.  I copied the first 4 files without difficulty.  However, when I try to copy c:\windows\system32\config\default to create a tmp file, the system cannot find the specified file.  Can I continue with the rest of the instructions?  Or it will not work without the default file?

  1. At the Recovery Console 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

  Give it a shot and see where it leads you. Can't say anything for sure.

• I only part I to recover from a corrupt registry! Help

  A couple of weeks, I had a Windows XP didn't start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SYSTEM.  I did a restore using the following
  First part
  In the first part, you start the Recovery Console, create a temporary folder, back up the existing registry files to a new location, delete the registry from their existing location files and then copy the registry files in the repair folder to the System32\Config folder. When you have completed 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 took place after Setup has finished are lost.

  The full, first part, follow these steps:

  1. Insert the diskette of starting Windows XP in the floppy drive, or insert the Windows XP CD into the CD-ROM drive and restart the computer.
     Click to select all of the options required to start the computer from the CD-ROM drive if you are prompted to do so.
  2. When the "Welcome" screen appears, press R to start the Recovery Console.
  3. If you have a dual-boot or multiboot, 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 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 the Recovery Console. Your computer will restart.

  Note This procedure assumes that Windows XP is installed in the C:\Windows folder. Make sure that replace C:\Windows with the appropriate dossier_Windows if it is a different place.

  If you have access to another computer, to save time, you can copy the text in step 5, and then create a text file called "Regcopy1.txt" (for example). To use this file, run the following command when you start in Recovery Console:

  batch regcopy1.txt

  With the command batch to the Recovery Console, you can process all the commands in a text file in the order. When you use the batch command, you do not have to manually type as many commands. Second part to perform 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 use Windows XP Home Edition, you can connect as an administrative user. If you sign in as an administrator, you must first start Windows XP Home Edition in safe mode. To start the computer in Windows XP Home Edition in safe mode, follow these steps.

  Note Print these instructions before continuing. You cannot view these instructions after you restart the computer in Mode safe. If you use the NTFS file system, also print the instructions from article KB309531 of the Knowledge Base. 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 boot menu.

  3. Use the arrow keys to select the appropriate safe mode option and press ENTER.
  4. If you have a dual-boot or multiboot 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 of their location saved files by using the system restore. This folder is not available in the Recovery Console, and is usually not visible on the typical use. Before you begin 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, select Show hidden folders and files, and then click to clear the Hide protected (recommended) operating system files check box.
  5. When appears in the dialog box confirming that you want to display these files, click Yes .
  6. Double-click the drive where you installed Windows XP to display the list of folders. If it is important to click on the correct drive.
  7. Open the System Volume Information folder. This folder is not available and is dimmed because it is defined as a file hidden doubling.

     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 article in the Microsoft Knowledge Base for access to this folder and continue with the procedure:

  309531 (http://support.microsoft.com/kb/309531/) how to access the System Volume Information folder
• Open a folder that was created not at the present time. You may need 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. Here are the restore points.
• Open one of these folders to find a subfolder of the snapshot. The following path is an example of a folder path to the snapshot folder:
  C:\System Volume \RP1\Snapshot Information\_restore {D86480E3-73EF-47BC-A0EB-A81BE6EE3ED8}
• Starting 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
• Rename the files in the C:\Windows\Tmp folder as follows:
  • Rename _REGISTRY_USER_. DEFAULT 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 system restore registry files. 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 the first part. Therefore, it is important not to use the most recent folder, especially if the time stamp on the folder is the same at the moment.

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

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

Note The procedure described in this section assume you are using your computer with the FAT32 file system. For more information on how to access the folder of information system with the NTFS file system Volume, click on the number below to view the article in the Microsoft Knowledge Base:

309531 (http://support.microsoft.com/kb/309531/) how to access the System Volume Information folder

Part three in the third part, you delete the existing registry files, and then copy the system restore registry files to the C:\Windows\System32\Config folder:

1. Start the 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 the Recovery Console. Restart the computer.

Note This procedure assumes that Windows XP is installed in the C:\Windows folder. Make sure that replace C:\Windows with the appropriate dossier_Windows if it is a different place.

If you have access to another computer, to save time, you can copy the text in step 2, and then create a text file named "Regcopy2.txt" (for example). To use this file, run the following command when you start in Recovery Console:

regcopy2.txt batch

Fourth part

1. Click Startand then click all programs.
2. Click on Accessories, then System Tools.
3. Click System Restore, and then click restore to a previous RestorePoint.

But after the game, I, my system was up and so I didn't do parts 2 3 & 4.  The other day I got the same error message when I started so I thought that no problem I'll try that again.  Except when I get to the part in part I say type md tmp go, I get the message that this file already exists.  Can some help me with this you problem, I have tons of photos and music that I need to register!  I had windows xp professional with all service packs.

rgmcmanus,
If the tmp folder already exists then you can either remove and then recreate with the command "rd tmp" or you can just create a different name like tmp1.  If you keep the registry errors you may need to back up all your data and then do a clean install. Mike - Engineer Support Microsoft Answers

  Your machine should have the Nvidia integrated graphics in addition to the physical Nvidia graphics card installed. If you remove the graphics card and plug your monitor on the port of the integrated graphics card you can get display. You need a DVI to VGA for your cord because the Nvidia card has DVI port and the port of the integrated graphics card is probably VGA port.

• How can I synchronize catalogs on 2 computers that use the same location for the image files?

  I do not understand Lightroom.

  For example, I use LR4.2 on a desktop computer and a laptop computer. Two computers (Windows 7 64-bit) go to the same image files. On my laptop in a folder, I have 42 master images and 5 virtual (virtual events) for a total of 47 images. But when I open LR4.2 on the desktop I do not see the 5 virtual (virtual events) on the 42 master images.

  Why can not I see the 5 virtual events since I can access the exact file and how I see the virtual evidence created on the laptop on the desk.

  It has no function in LR to synchronize catalogs.

  If your pictures are on an external hard drive, you can move the file catalog to this external hard drive, and then you will have a catalogue on your desk and another on the laptop. Just use the one on your external hard drive.

  If your pictures are on a network drive, you can not put the file catalog here, so the only answer I know is to manually transfer the catalog back from one computer to the other file.

  Why can I not see the 5 virtual events since I can access the correct folder

  Lightroom does not save your work to the photo files. It stores your work in the Lightroom catalog file.
