First, boot up troubleshooting

"Q": My operating system is Windows XP, but after the start of the login interface, click on the user name to log in, "is loading personal settings" after the cancellation of their own, excuse me, what is the reason?

"Answer": most likely because the Userinit key value in Hkey_local_machine/software/microsoft/windowsnt/currentversion/winlogon is modified, the normal key value should be C :/windows/system32/userinit.exe (Note: C disk is the operating system's letter).

At this point, we want to make sure that there are userinit.exe in the C:/windows/system32, on the other hand, you can edit a reg registry file, which reads as follows:

Windows Registry Editor Version 5.00

[Hkey_local_machine/software/microsoft/windows Nt/currentversion/winlogon]

"Userinit" = "C:/windows/system32/userinit.exe,"

You can then run the registry file and, of course, use WinPE ERD2003 to modify the registry directly to restore the Userinit key value above.

"Q": How can I solve the "NTLDR is missing" error message when Windows XP starts?

"A": NTLDR is located in the root directory of the operating system's disk, just extract the file from the Windows installation disk and copy it to the system's packing directory.

You can also use the Windows XP installation CD to boot to Recovery Console mode, enter the command prompt environment, enter "Fixboot" and run (enter without double quotes, same below) to resolve the failure.

The Recovery Console is enabled in the following ways:

Step 1: Insert a Windows XP installation CD before the system starts, and enter the BIOS to set the CD-ROM as a priority;

Step 2: After restarting the computer, the system will automatically enter the Windows XP installation Interface option, press the "R" key to select item 2nd "To use the fault console to repair the Windows XP installation, press R." The system automatically logs on to the Recovery Console and the Recovery Console is successfully started.

Q: Why does my Windows XP reboot after a splash screen and I can't get into the operating system?

"Answer": first, you can use anti-virus software to kill the operating system is infected with the virus, if there is no virus, then the main reason is due to Kernel32.dll files are missing or damaged, can be resolved as follows:

Using the Windows XP Setup disk to enter Recovery Console mode, in the command prompt, enter the following command:

CD System32

ren Kernel32.dll kernel32.old (Note: If Kernel32.dll no longer exists, you may not use this command)


Expand E:/i386/kernel32.dl_ (E disk for the drive letter for placing the Windows XP installation disk)


Q: After I updated the driver for a hardware, I found that Windows XP could not start, would you like to reload the operating system at this time?

"Answer": you do not need to reinstall the operating system, you can use the following two ways to resolve:

Method 1: After the first failure, you can press the function key F8 before the operating system boots, and then select the "Last Known Good Configuration" menu item on the menu that appears to win7 system download.

Method 2: When the previous method is not valid, press the function key F8 before the operating system boots, and then select the Safe Mode option on the menu that appears to enter Safe mode. On the desktop, press the right mouse button on my computer, and select the Properties command in the right-click menu. Click the Hardware tab in the System Properties dialog box, click the Device Manager button, right-click the hardware device that is generating the problem, select the Properties command on the right-click menu, and click on the Open dialog box. Driver tab, and then click the "Go back to Driver" button.

"Ask": My computer can not enter Safe mode, how to solve?

"Answer": You can use the following two ways to resolve:

Method 1: When you start the computer, press the F8 function key, after you turn on the Windows XP Advanced Options menu, select the "Last Known Good Configuration" item on the menu list, and then enter.

Method 2: Insert the Windows XP installation CD in the optical drive and restart the computer using the CD, enter the Windows XP installation Interface option, press the "R" key to automatically log on to the Recovery Console, and at the command prompt, type the password for the local administrator account. Then type the "Fixboot" command and press the "enter" key to fix the startup problem by writing the new partition boot sector to the system partition. Finally, type the exit command, press the ENTER key, exit the Recovery Console, and restart the computer.

"Q": When I add a password to the Windows XP Administrator account, I log in automatically and find it very slow to start up on the desktop with this account.

"Answer": most of the reasons for this is because the administrator to add a password and automatic login will be generated, you can use the following methods: When the system is restarted to press the function key F8, in the presence of the Advanced Options menu, select "Safe Mode", Then enter the password of the administrator user and enter the security mode interface of the operating system. Click the "Start" button, enter the "Control userpasswords2" command in the "Run" button, and click "OK" to open the "User Account" dialog box.

Check "To use this computer, the user must enter a username and password" option, so that after the restart can appear multiple user login interface, and then select a user and enter the appropriate password to resolve the startup failure.

Q: My Computer is originally a Windows 98 and Windows XP of the dual operating system, and later upgraded Windows 98 to Windows 2000, but after the upgrade found that Windows XP can not start, how can i solve?

"A": This is because Windows XP was installed before, and when Windows 98 was upgraded to Windows 2000, because Windows 2000 rewrote 3 important startup file Ntldr,,boot.ini, which causes Windows 2000 to fail to boot Windows XP, causing Windows XP to fail to start.

The workaround is simple, extracting the two files from the I386 directory of the Windows XP installation CD, and then copying them to the root directory of the system boot partition and setting them to read-only, hidden properties, so that you can start Windows XP operating system.

In addition, if you plan to change the default startup option back to Windows XP, you can also use Notepad to edit the Boot.ini file, and then copy the file's startup entry to "default=" for a deep XP system download.

For example, if you want Windows XP to be the default startup project, you can change the text content of Boot.ini to



Default=multi (0) disk (0) rdisk (0) partition (2)/window s

[Operating Systems]

multi (0) disk (0) rdisk (0) partition (1)/windows= "Micro soft Windows2000 profeessional"/fastdetect

multi (0) disk (0) rdisk (0) partition (2)/windows= "Micro soft Windows XP"/fastdetect

Finally, make it read-only, hide the attribute, and save it to the root directory of the system boot partition.

If the Boot.ini file is not found, you can go to the operating system desktop, open the My Computer window, in turn, execute the tools → Folder Options command in the menu bar, select the View tab, and then "Hide protected by OS": My computer is equipped with Windows 98 and Windows XP, reinstall Windows 98 after a period of time, causing Windows XP to fail to start and how to troubleshoot this problem?

"A": this is because the reinstall of Windows 98 is caused by overwriting Windows XP startup files that are located in the root directory of the system boot partition.

We can put the Windows XP installation disk into the optical drive, and then install Windows XP, until it copies the installer to your disk immediately stop, and then go back to the root of the system boot partition, edit the root directory of the Boot.ini file, all of which "$" can be deleted. After you edit the Boot.ini file, change it back to a hidden, read-only property.

"Q": My computer is originally Windows XP and Linux dual operating system, and then after the Linux uninstall, can not start Windows XP, how to deal with?

"A": After uninstalling the Linux operating system, its boot loader manager remains on the master boot record on the hard disk, causing Windows XP to fail to start, with only Windows XP's own boot loader manager overriding the master boot record to resume startup.

Using the Windows XP Setup disk to boot to the Recovery Console, enter the "FIXMBR" command at the command prompt, and then press ENTER to show "Are you sure you want to write a new master boot record?" Prompt, enter "Y" and return to the.

"Q": When the computer is turned on, always automatically scan the disk, what is going on?

"A": Normally, if the computer is not shut down normally, it will be automatically scanned at the next boot, and if the scan is canceled during the scan, a similar situation will still occur the next time the boot is turned on. So we might as well scan it thoroughly once. In addition, after entering the system desktop, select Start → run, and then enter "CHKNTFS/C" in the dialog box (C is the System Setup disk).

"Q": Windows XP prompts the following error at startup "C:/windows/system32/config/system error, please fix", how can I fix it?

"A": you can use the Windows XP installation CD to boot the machine into the fault console, and then run copy c:/windows/repair/system c:/windows/system32/config/system at the command prompt. Select Yes if you want to eject the prompt to overwrite.

"Ask": After starting up a folder will automatically pop up, how to deal with?

"Answer": you can determine in advance whether the computer virus. If you have excluded the virus factor, enter "Msonfig" in the "Run" column to open the System Configuration Utility window. For example, if you always open the "C:/ls" folder, you can click the "Startup" tab in the System Configuration Utility to check for "C:/ls" items. If so, remove the "√" in the check box before the item.

Next click on the "System.ini" tab, open the section title "Boot", check the first line "shell" there is no "c:/ls", if there is, then enter the edit state to delete the XP system download.

Then check the "Win.ini" tab, open the section heading "Windows" Check the settings line "load=" and run= "there is no" c:/ls ", if there is to enter the editing state to delete it.

Of course, we can also go to Registry Editor, look up the key values for "C:/ls", see if they are in the "RUN" key, or delete them directly if they are available.
