Cannot Start Windows XP if the System or Software Hive Is Missing or Damaged

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

To resolve this issue, use one of the following methods.
Use the Recovery Console Tool:

To restore a damaged registry hive, use the Recovery Console to restore the

backup copy of the hive from the Repair folder. The Repair folder contains a
copy of the system's registry hives that were created after the first successful
startup of Windows XP.

WARNING : Although data should not be affected by the following procedure, you
may need to restore changes you previously made to programs or system settings
since the first time you successfully started Windows XP.

To replace the damaged registry hive and restore the backup copy of the hive
from the Repair folder: Start your computer to the Recovery Console.

Determine if the file that is mentioned in the "Symptoms" section of this
article is present, and if it is, rename it:

In Recovery Console, change to the c:\Windows folder.

Type cd system32\config , and then press ENTER.

Type dir system , and then press ENTER.

If you cannot run the preceding command successfully (because the file is
missing), skip to step 3. If you can run the preceding command successfully,
type ren system system.bak , and then press ENTER.

NOTE : If the message that you received referred to the software file, replace
"system" with "software" in the preceding command. For example, you would type
ren software software.bak (instead of ren system system.bak ), and then press

Removing Invalid Entries in the Add/Remove Programs Tool

Start/Run/Regedit

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall

Each program listed in Add/Remove Programs has a subkey listed here. Locate the correct subkey for the program in question and right click it, then select Delete. You may want to choose Export, first, to export the key to a REG file. The REG file can be re-imported if you find you made a mistake.

You may have to contact the manufacturer of the program that you want to remove if you need to clean up the disk and registry entries. The procedure described in this section does not remove all the files and registry entries used by the program; it removes only the reference in the Add/Remove Programs tool.

Note: Other checkpoints to consider when trying to remove a program:

Check to see if the software/program is listed here: Start/Run/Regedit

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

1. Right click the Program's shortcut/Properties to gain the Target Path.

2. Go to Start/Run/Msconfig/Startup and make sure it is not listed or checked there. If so, uncheck it and remove the program listing from here: Start/Run/Regedit

For items that were in the Start menu, Programs, Startup folder:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\MSConfig\startupfolder. You'll find a subkey for each disabled item.

For items loaded from the Registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\MSConfig\startupreg. Again, you'll find a subkey for each disabled item.

Clear Disabled Items from Msconfig Startup (Line 148)

NTLDR is missing, press any key to restart

The quick test to make sure your OS installation is still good is to create an MBR and NTLDR on a floppy disk and check your partitions, this disk will check many of the partitions for a working windows installation. Here are the instructions to do this:

1. Get a blank floppy (whatever is on it will be erased), and put it into a working computer.

2. Download fixntldr.exe onto a working computer

3. Run the fixntldr.exe file by double clicking it. Click OK to overwrite the blank floppy disc in the working computer, you should see some screens about writing a new floppy disk.

4. Do you remember if the folder you had your Windows installation in was named "Windows"? If you can't remember just keep going.

5. Put the new floppy you have just created into the computer that gets the NTLDR is missing error message, turn the broken computer off.

Using the boot disk in the computer with the "NTLDR is missing" error.

Start back up the broken computer with the floppy in the floppy drive. Once your computer gets past the BIOS screen your computer should try to access the floppy drive and you should see a black screen with white letters that says:

1ST TRY THIS seleccione esto primero
2ND TRY THIS essayez ceci en deuzieme
3RD TRY THIS wahlen Sie diesen Third
4TH TRY THIS selezioni questo fourth
5TH TRY THIS selecione este fifth
6TH TRY THIS seleccione este sexto
7TH TRY THIS essayez ceci en septieme
8TH TRY THIS wahlen Sie dieses achte
9TH TRY THIS selezioni questo nono
10TH TRY THIS selecione este decimo

(I threw in some Spanish / French / German / Italian / Portuguese for international flavor.)

This file is set up to automatically select the "1ST TRY THIS" choice after 30 seconds. Try it first, if it was the wrong selection, you will likely get one of these three errors:

1. Windows could not start because file "\system32\hal.dll was missing or corrupt

2. Windows could not start because of a computer disk hardware configuration problem. Could not read from the selected boot disk. Check boot path and disk hardware. Please check the Windows documentation about hardware disk configuration and your hardware reference manuals for additional information.

3. I/O Error accessing boot sector file multi(0)disk(0)fdisk(0)\BOOTSECT.DOS

4. Immediate reboot

If you get the immediate reboot or some other weird error, try pressing F8 at the "1st Try This" selection screen, it will give you a prompt where you can select Safe Mode, and then try the "1st Try This" option again. Safe Mode is a special "minimal" version of Windows that doesn't load certain parts of the operating system that might have caused the problem.

One of the choices should eventually boot you back into Windows. (If you go all the way to option 10 and still get errors on startup, try changing boot.ini to windows.ini, then winnt.ini to boot.ini, and run through all 10 possibilities again.

Use windows to fix the boot files on the hard drive.

Once you get back into windows, try to change back whatever you were last doing and boot normally, it that doesn't work, go to the root of your C:\ drive and rename boot.ini to boot.ini.bak, ntldr to ntldr.bak, and ntdetect.com to ntdetect.com.bak, then copy the files that are on your floppy disk to the root of your C:\ drive (if you used the CD-ROM, download the fixntldriso.zip file and use the boot files from there) so that the files are on the root, like C:\ntldr C:\ntdetect.com C:\boot.ini. If it prompts you to overwrite a file, press "Yes". After they have been copied over, be sure to remove the "Read-Only" attribute from the properties of the files. (Right click on a file, choose properties, and uncheck the Read-Only box). Take the floppy out and reboot the computer (you should see the "1st Try This" menu, make the same selection you did before.

If you get back into Windows again, you can change that "1st Try This" menu by going into Start > Control Panel > System > Advanced tab > Startup and Recovery section, Settings button > System Startup; then change the "Default Operating System:" to the selection that worked for you, and change the box that says "Time to display list of operating systems" to however many seconds you want (usually 1 second). Click OK twice.

Recovery Console in Windows XP

Recovery Console in Windows XP

Description of the Windows Recovery Console

This section describes the functionality and limitations of the Windows Recovery Console. The Windows Recovery Console is designed to help you recover when your Windows-based computer does not start properly or does not start at all.

When you use the Windows Recovery Console, you can obtain limited access to NTFS, FAT, and FAT32 volumes without starting the Windows graphical interface. In the Windows Recovery Console you can:

Use, copy, rename or replace operating system files and folders, Enable or disable services or devices from starting when you next start your computer, Repair the file system boot sector or the Master Boot Record (MBR), Create and format partitions on drives.

Note that only an administrator can obtain access to the Windows Recovery Console so that unauthorized users cannot use any NTFS volume. More Information.

To install the Recovery Console as a Startup Option

With Windows running, insert the Setup CD into your CD-ROM drive. Start/Run/X:i386\winnt32.exe /cmdcons. Follow the instructions on the screen.

Notes:

To run the Recovery Console, restart your computer and select the Recovery Console option from the list of available operating systems.

You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings may also prevent you from completing this procedure.

To see the commands available on the Recovery Console, type help at the at the console prompt.

To start the computer and use the Recovery Console

From the Setup CD-ROM

Insert the Setup compact disc (CD) and restart the computer. If prompted, select any options required to boot from the CD.
When the text-based part of Setup begins, follow the prompts; choose the repair or recover option by pressing R. If you have a dual-boot or multiple-boot system, choose the installation that you need to access from the Recovery Console. When prompted, type the Administrator password. At the system prompt, type Recovery Console commands; type help for a list of commands, or help commandname for help on a specific command.

To exit the Recovery Console and restart the computer, type exit.

If you have already installed the Recovery Console

During Startup, select Recovery Console from the startup options menu. If you have a dual-boot or multiple-boot system, choose the installation that you need to access from the Recovery Console. When prompted, type the Administrator password. At the system prompt, type Recovery Console commands; type help for a list of commands, or help commandname for help on a specific command. To exit the Recovery Console and restart the computer, type exit.

Important Note: Because the Recovery Console is quite powerful, it is recommended for use only by advanced users or administrators.

To Delete the Recovery Console

Open My Computer.
Double-click the hard drive on which you installed the Recovery Console.
On the Tools menu, click Folder Options.
Click the View tab.
Click Show hidden files and folders, clear the Hide protected operating system files check box, and then click OK.

A Discussion About the Bootcfg Command and Its Uses

The bootcfg command is a Microsoft Windows XP Recovery Console command that manipulates the Boot.ini file. This command has a function that can scan your hard disks for Microsoft Windows NT, Microsoft Windows 2000, and Windows XP installations, and then add them to an existing Boot.ini file or rebuild a new Boot.ini file, if one does not exist. The bootcfg command enables additional Boot.ini file parameters to be added to existing or new entries.

To use the bootcfg command, start the Recovery Console with the Windows XP CD-ROM, and then click Recovery Console. Or, install the Recovery Console locally, and then select the command from the Boot menu. More Information.

How to Boot Windows Preinstall Environment from a Hard Disk

This section describes how to configure the Windows Preinstall Environment (WinPE) to boot from a hard disk.

NOTE: More than likely the supported methods to boot WinPE (by means of a CD-ROM or from a Remote Installation Services (RIS) server) are the most commonly used methods. The method that is described in this article is provided for
informational purposes. More Information.

Access Floppy Drive from Recovery Console

To enable write access to floppies from within the R.C., click Start, Programs, Administrative Tools, Local Security Policy. Under Local Policy, Security Options, double-click "Recovery Console: Allow floppy copy and access to all drives and all folders." Select Enabled, then click OK.

Note: The following steps may also be necessary:

"After you enable the security policy, it must be applied (possibly across the domain) before becoming the effective policy on the local computer. This is necessary before the set command is truly enabled and available for use during a Recovery Console session. You can run the following command to force a refresh of the local computer's policy after performing the policy change listed above: secedit /refreshpolicy machine_policy

After the local policy is refreshed and the enabled Recovery Console security policy is in effect, you should be able to start Recovery Console and use the set command to enable any of the four environment options."

In the Recovery Console, you must then type: set AllowRemovableMedia = TRUE

Accessing Other Folders in Recovery Console

This security policy will also access to files and folders other than the defaults (normally access is restricted to \winnt and \cmdcons). To enable access to other folders, simply boot to the Recovery Console command prompt and type: set AllowAllPaths = true

You will then be able to access other files and folders on your computer. Please keep in mind that this is a potential security problem, and that you should be careful to restrict physical access to computers that are configured in this way.

Windows Update Site Problems

To protect your computer, you need the proper updates for your operating system. This is Number Two on the list of "Must do" to protect your computer.

Any operating system must be kept up to date. Without the updates, your computer will become increasingly more vulnerable to new threats.
Some of these threats are made possible by weaknesses discovered in Windows after Windows was released. Other weaknesses became apparent as new technology creates a weakness where there was none before.
Windows has made it easy to keep up to date
You can perform Windows Update automatically, prompted or manually.

Windows ME, 2000 & XP:
To set Windows Update on automatic (recommended for most home users)
Right click "My Computer"
Click "Properties"
Click "Automatic Updates"
Place check in "Keep my computer up to date"
Also place a bullet in "Automatically download the updates"
NOTE: Be sure your computer is powered on the day/time you set.
To set Windows Update to prompt for the updates choose one of the other two bullets on that page.
To manually update:
Start/All Programs/Windows Update
Follow the prompts.

Windows 9X:
Double click "My Computer"
Double click "Scheduled Tasks"
Double click "Windows Critical Update Notification"
You can make selections as desired.
If the option is not available install Windows Critical Update Notification:
1. Go here:
http://windowsupdate.microsoft.com
2. Click "Scan for updates"
3. On the left side click "Windows 98 and Windows 98 Second Edition"
4. Click "Add" by "Windows Critical Update Notification recommended update"
5. Click "Review and install updates"
6. Click "Install Now"

You should install ALL Critical Updates.
Install the Recommended Updates that you have determined apply to you.
Get the drivers directly from the manufacturer

If you have not updated in a while, you may have a lot of updates.
Install Service Packs first and by itself
Reboot
Install updates no more than three at a time.
Reboot
Install next three.

Don't forget to check for and install updates for other software such as Microsoft Office.

Repair the Boot Sector

If XP won't start it may be due to a damaged boot sector or a missing or corrupt ntldr or ntdetect.com files.

To replace damaged ntldr and ntdetect.com you can copy fresh files from the XP CD using the COPY command. Boot with the XP CD and enter the Recovery Console (as above). At the Command Prompt type the following (where "X" is your CD-Rom drive letter) allowing the files to overwrite the old files
COPY X:\i386\NTLDR C:
COPY X:\i386\NTDETECT.COM C:

To repair a damaged Boot Sector at the command prompt type FIXBOOT and press Enter. Then answer "Y"

How To Create a Boot Disk to Start Windows XP

Create a Windows startup disk when you first install Windows on the computer. This disk is different from an MS-DOS startup disk. Unlike MS-DOS, the whole Windows operating system cannot fit on one floppy disk. A Windows startup disk contains only the files that you must have to start the operating system with the remainder of the Windows system files installed on the hard disk drive. To create the startup disk, follow these steps:

1.	Insert a blank floppy disk in drive A, and then format the disk by using Windows XP.
2.	From the root folder of the system partition of your hard disk drive (for example, C:\-), copy the following files to the floppy disk: Boot.ini NTLDR Ntdetect.com You may have to remove the hidden, system, and read-only attributes from the files.
3.	Restore the hidden, system, and read-only attributes to the files on your hard disk if you removed these attributes.
4.	If the Bootsect.dos file or the Ntbootdd.sys file resides in the system partition, repeat steps 2 through 4 to copy these files to the boot disk.
