WindowsXP system startup failure ten strokes to solve If your computer's power has been turned on, but WindowsXP does not start normally, you have to take some troubleshooting. Let's talk about possible problems and how to solve them. 1. Using the Windows boot disk If the boot problem is caused by the boot record of the active partition or the file used by the operating system booting, the boot disk can solve the problem. The specific method is as follows: Create a Windows boot disk, find a Windows XP machine with similar configuration and working normally, open my computer, right-click and select the disk icon, and then select Format in the subsequent menu. When the formatting dialog appears, keep all the default settings and click the Start button. When the formatting operation is complete, close the formatting dialog and return to MyComputer. Double-click the C: drive icon to access the root directory and copy the three files Boot.ini, NTLDR, and Ntdetect.com to disk. Once you have created the Windows boot disk, insert it into the drive of the failed system and press Ctrl+Alt+Delete to restart the computer. 2. Use the last correct configuration You can also try to start the operating system with the last correct configuration. This feature allows you to cancel any problem-causing changes made on the CurrentControlSet key of the registry, which defines the hardware and drive settings. The KnownGoodConfiguration function replaces the current key value with the CurrentControlSet key value that was last started by the system. The specific method is as follows: First press Ctrl+Alt+Delete to restart the computer. When you see “Pleaseselecttheoperatingsystemtostart” appears on the screen, or you hear a beep from the computer, press F8 and the Windows Advanced Options menu will appear on the screen. Select the “LastKnownGoodConfiguration” option from the menu and press Enter. Keep in mind that you only have one chance to use the LastKnownGoodConfiguration feature. 3. System Recovery Another tool that can help solve Windows XP startup problems is system recovery. System recovery runs as a service in the background and continuously monitors changes to critical system components. When it finds that a change is imminent, system recovery immediately makes a backup copy of the recovery point for these important components before the change occurs, and the default setting for system recovery is to create a recovery point every 24 hours. The specific method is as follows: First press Ctrl+Alt+Delete to restart the computer. When you see “Pleaseselecttheoperatingsystemtostart” appears on the screen, or you hear a beep from the computer, press F8 and the Windows Advanced Options menu will appear on the screen. Now select Safe Mode from the menu and press Enter. When Windows XP enters safe mode, click the Start button, select the All Programs Accessories System Tools menu, and select System Recovery. Click Next to select a recovery point and start the recovery process. 4, use RecoveryConsole If WindowsXP startup problems are more serious. You can boot the system using Windows XP CD and then use a tool called Recovery Console. Here's how: Insert WindowsXPCD into the CD-ROM drive of the failed computer, then press Ctrl+Alt+Delete to restart the computer. Once the system is booted from the CD, it is easy to load the basic files needed for booting as prompted. When you see the WelcomeToSetup interface, press the R key to enter the RecoveryConsole. Then you will see the RecoveryConsole menu. It shows the folder containing the operating system files and prompts you to select the operating system you plan to log in to. You need to enter the serial number on the menu on the keyboard, and then the system will prompt you to enter the administrator password, you will enter the main RecoveryConsole prompt page. 5. Repair the damaged Boot.ini With the Windows XP operating system loaded, the Ntldr program points to the Boot.ini file to determine the location of the operating system files and which boot option to choose. So if there is a problem with the Boot.ini file, the Windows XP system will not start. You can fix it using the special version of the Recovery Console Bootcfg tool. Of course, you must first restart the system with Windows XP CD and open RecoveryConsole as described in #4. You can call the Bootcfg tool like this: At the RecoveryConsole command prompt, type Bootcfg/parameter where /parameter is one of these required parameters: /Add: scans all Windows installations to help you add anything to the Boot.ini file. New content. /Scan: Search all Windows installations. /List: Lists all entries for the Boot.ini file. /Default: Sets the default operating system as the primary boot entry. /Rebuild: Completely re-create the Boot.ini file. The user must confirm each step. /Redirect: Allows the operating system to redefine to a specific port when using the HeadlessAdministration function. Redefinition includes two parameters: PortBaudrate and UseBiosSettings. /Disableredirect: Disable redirection. 6, repair the damaged partition boot record partitionbootsector is a small part of the hard disk partition, which contains information about the file system in the operating system and a small machine language program, which is crucial to help the operating system boot. If you suspect that the startup problem with Windows XP is caused by the partitionbootsector being corrupted, you can fix it using a tool called Fixboot in the Recovery Console. First, start the system with Windows XP CD and open RecoveryConsole as described in #4. You can call the Fixboot tool like this: At the RecoveryConsole command prompt, type Fixbootdrive:drive to represent the partition where you want the newly created partitionbootsector to be located. 7. Repair the damaged primary boot sector The primary boot sector occupies the first sector of the hard disk and is responsible for the Window boot process. The primary boot sector contains the disk partition table and a small program called the master boot code, which is responsible for locating activity 0, bootable disk, and partition in the partition table. Once it is destroyed, the partitionbootsector will take over and start loading Windows. If the primary boot sector is corrupted, the partitionbootsector will not be able to do this and Windows will not be able to boot. If you suspect that the Windows XP system boot problem is caused by the main boot sector being corrupted, you can fix it using the Fixmbr tool in the Recovery Console. First, start the system with Windows XP CD and open RecoveryConsole as described in #4. You can call the Fixmbr tool like this: At the RecoveryConsole command prompt, type Fixmbrdevice_name:device_name is the pathname of the device where you want the new primary boot sector. For example, the device path name is formatted according to the standard bootable drive C drive: \\Device\\HardDisk0. 8. Disable automatic restart If Windows XP encounters a fatal error, the default setting for handling this error is to automatically restart the system. If the error is generated during Windows XP startup, the operating system will fall into the infinite loop of restart —— iteratively restarts and cannot be restored. In this case, you need to disable the auto restart feature. To do this, when Windows XP starts, when you see “Pleaseselecttheoperatingsystemtostart”, or after you hear a beep, press F8 to open the Windows Advanced Options menu. Then, select to disable automatic restart in the event of a system failure and press Enter. Now Windows XP will hang when it encounters a problem, it will give a stop message that you can use to diagnose the problem. 9. Restore Backup If you can't fix a Windows XP system with a boot failure, but have a recent backup, you can restore the system from the backup media. The method used to recover your system depends on the backup tool you use, so you need to restore the system according to the instructions of the backup tool. 10. Perform an in-place upgrade If you can't fix a Windows XP system with boot problems and haven't backed up recently, you can do an in-place upgrade. Reinstalling the operating system in the same folder is like upgrading from one Windows version to another. In-place upgrades can solve at most most of the problems if they don't solve all Windows startup problems. Here's how: Insert the Windows XP CD into your drive and restart your system from the CD. After the initial preparation is complete, you will see the Windows XP installation screen. Press Enter to enter the Windows XP installer. Soon, you will see the license agreement page, then you need to press F8 to confirm that you agree to the agreement. The installer then searches the hard drive for the previously installed Windows XP. When it finds the previously installed Windows XP, you will see a second Windows XP installation interface appearing on the screen. The interface will prompt you to press R to repair, or press Esc to reinstall a Windows XP. In this case, repairing the system is the same as doing an in-place upgrade, so you can fix it by simply pressing the R key. After you have chosen it, the installer will check the disk where the system is located and then start an in-place upgrade. After an in-place upgrade or repair system, you must reinstall all Windows updates.
