Decompose how to troubleshoot Windows XP startup failure

After your computer's power has been turned on and Windows XP is not booting properly, you need to take some troubleshooting steps. The following is a list of possible problems and ways 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 My Computer. Double-click the C: drive icon to access the root directory and copy the three files Boot.ini, NTLDR, and Ntdetect.com to disk. After creating 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 Known Good Configuration 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 “Please select the operating system to start" on the screen, or hear a beep from the computer, press [F8] and the Windows Advanced Options menu will appear on the screen. Select the “Last Known Good Configuration” option from the menu and press [Enter]. Keep in mind that you only have one chance to use the Last Known Good Configuration 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 “Please select the operating system to start" on the screen, or 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.
