Windows XP startup Fault Diagnosis

Win XP optimizes the system as a whole, so the startup speed is not only much faster Than Win 2000, but also much faster than Win 9x. However, many users find that Windows XP cannot be guided after upgrading or installing other drivers. How can they solve such problems?

Fault 1: Windows XP and Windows XP are installed on a friend's computer. After using Windows 98 for a while, Windows XP cannot be started.

Fault analysis: the re-installed Win98 overwrites the XP Startup file located in the root directory of the system startup partition, causing XP to fail to start.

Troubleshooting: The fault will be solved if you know the cause. The key to solving the problem is to reinstall the XP OS _Loader prompt: Win NT/2000 and Win XP Boot Program), put the XP installation disk into the optical drive, and then enter the XP installation program, wait for it to copy the installer to your disk and immediately stop it. Then return to the root directory of the system startup partition and edit Boot. INI file, delete all "$. It is important to note that we must master the installation measurement, because we only install the XP boot program instead of reinstalling XP! The Boot. ini file cannot be found! Okay, let me introduce how to find the OS _Loader Startup file:

First, confirm and find the system boot partition and enter its root directory. Then, open the "Tools" menu in the menu bar, select "Folder Options", and select the "View" tab in the "Folder Options" window, remove the check box before "Hiding files protected by the operating system)". A warning dialog box will pop up. You don't have to worry about it. Just select "OK. In addition, place "hide files and folders" in "show all files and folders", select "OK" and return to the System Disk directory. Then, you will find that the "hidden files and folders" are in this directory, there will be many systems and hidden files, you can find the Boot. ini, ntldr. nt, detect.com are three important startup files. Note: After editing Boot. after the INI file, make sure to change the change back ).

Fault prevention: in fact, such a fault can not occur, as long as you re-install Win98, use Win98 boot disk to start, in this case, the "Win 98 installation" option will appear on the startup screen. Select it and you can install it with peace of mind!

Fault 2: My friend's computer was originally Windows 98 and Windows XP, and later I thought Windows 98 was not stable enough, so I upgraded it to Win2000, which made Windows XP unable to start.

Fault Analysis: we upgraded Win 98 to Win 2000, and Win 2000 changed ntldr, ntdetect.com, and boot. among the three important startup files, Win 2000 cannot boot XP, causing XP to fail to start.

Fault solution: the key to solving this fault is to use WinXP to guide Win2000. Note: Win 2000 cannot guide XP, but XP can guide Win 2000 !), Start the system using the ntldr and ntdetect.com files of XP and enable XP to boot Win2000. Solution: Start Win 98 first, and then extract the ntldr and ntdetect.com files from the I386 directory of the XP installation disc, copy the two files to the root directory of the system startup partition and set them to read-only and hidden attributes. In this way, you can start your XP! If you want to change the default Boot option back to XP, you only need to use NotePad to edit the Boot. INI file, copy the XP startup entry to "default =", for example, bootloader timeout = 7 default = multi0) disk0) rdisk0) partition2) \ Windows = "MicrosoftWindowsXP"/fastdetect operatingsystems multi0) disk0) rdisk0) partition1) \ Windows = "MicrosoftWindows2000Profeessional"/fastdetectmulti0) disk0) rdisk0) partition2) \ Windows = "MicrosoftWindowsXP"/fastdetect. Finally, set it to read-only and save the hidden attribute to the root directory of the system startup partition!

Another method is to copy the three files from other machines with the same version of XP that can be started normally, and then use XP as the default option as needed) follow the above method to edit boot. just copy the INI file!

Fault prevention: you only need to back up the three startup files before the upgrade, and then install Win 2000 from the boot disk of Win 98, after the installation is complete, restore the three backup files to the root directory of the system startup partition to avoid the above troubles!

Fault 3: XP cannot be started after a friend's system updates a driver of XP.

Fault Analysis: it is clear that the newly installed driver has a problem, causing XP to fail to start!

Fault solving: the key to solving the fault is to use a stable and reliable driver to replace the current driver. If you encounter this problem under Win 98, you may first want to enter the security mode, and then delete or replace the current driver from the security mode. Where is the XP security mode available? XP's security mode can be called out without pressing Ctrl at startup like Win 98. So, where is XP's security mode hidden? In fact, it is easy to find. When you start XP, press F8 when the startup progress bar appears to bring up the XP Startup menu and select the safe mode. It is easy to enter the XP security mode. The quickest and easiest way is to use Windows XP to restore the system to its previous normal state. Of course, you can also use the old method for troubleshooting this type of problem under Win 98. We will certainly be able to handle it. I will not go into details here!

Fault prevention: XP startup failures caused by insufficient and stable XP drivers are common. We recommend that you do not use the latest driver when selecting the XP driver, unless you are willing to help with the test!

Finally, I would like to remind you not to be panic when encountering such faults. Be sure to be calm, carefully analyze the causes of the faults, and find a solution to the faults. I hope you can make good use of windows XP, fully experience the fun of digital life!
