Fault 1: My friend's computer is equipped with Win98 and WindowsXP. After using it for a while, reinstall Win98, causing Windows XP to fail to start.
Fault Analysis: Reinstalled Win98 will be overwritten by the XP startup file located in the root directory of the system boot partition, causing XP to fail to start.
Fault resolution: Knowing the cause, the fault will be solved. The key to solving the problem is to reinstall XP OS_Loader (Hint: WinNT/2000 and WinXP bootloader), put the XP installation disk into the CD-ROM drive, and then enter the XP installer, after it copies the installer to your disk. Stop immediately, then go back to the root of the system boot partition and edit Boot. Ini file, delete all of them “$”. Here to remind everyone to pay attention to the mastery of the installation, because we installed just XP bootloader instead of reinstalling XP! What, can't find Boot. Ini file! Ok, then let me introduce the way 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", select the “View” tab in the “Folder Options" window, and then hide the operating system. The protected file (recommended) & rdquo; before the hook is removed, then a warning dialog will pop up, do not care about it, select “ OK & rdquo; Also, you should put "Hidden files and folders" in the "Show all files and folders", select "Check" & then go back to the system disk directory, then you will find in this directory, There will be many system and hidden files, you can find the three important startup files Boot.ini, ntldr.nt, detect.com (Note: After editing the Boot.ini file, you must change the previous changes. come back). Prevention
failure: In fact, such a failure could not happen, as long as reload Win98, Win98 using a boot disk, then it will appear on the splash screen & ldquo; Win98 installation & rdquo; so An option, choose it, you can install it with confidence!
Fault 2: The friend's computer turned out to be Win98 and XP. After that, Win98 is not stable enough, and it is upgraded to Win2000, which causes WindowsXP to fail to start.
Fault Analysis: Upgrade Win98 to Win2000, Win2000 rewrote ntldr, ntdetect. Com, boot. Ini these three important startup files, Win2000 can not boot XP, causing XP can not start.
Fault resolution: The key to solve this fault is to boot Win2000 with WinXP (Note: Win2000 can't boot XP, but XP can boot Win2000!), that is, use XP's ntldr, ntdetect. The com file starts the system and lets XP boot Win2000. Solution: Start Win98 first, then extract ntldr, ntdetect from the I386 directory of the XP installation CD. Com file, copy these two files to the root of the system boot partition and set it to read-only, hidden properties. This will start your XP! If you usually use XP mainly and want to change the default startup option back to XP, just use Notepad to edit Boot. Ini file, copy the startup entry of the file XP to “default=”, such as bootloader timeout=7 default=multi(0)disk(0)rdisk(0)partition(2)\\Windows=“ MicrosoftWindowsXP”/fastdetect operatingsystems multi(0)disk(0)rdisk(0)partition(1)\\Windows=“MicrosoftWindows2000Profeessional”/fastdetectmulti(0)disk(0)rdisk(0)partition(2)\\Windows=“ MicrosoftWindowsXP”/fastdetect Finally, put it as read-only, hidden properties are saved to the root directory of the system boot partition!
Another method is to copy these three files from other machines that can be started normally and have the same version of XP, and then edit the boot according to the above method (XP is the default option). Ini file will do!
Failure prevention: Just backup the three startup files before the upgrade, then install Win2000 from the Win98 boot disk. After the installation is complete, restore the three backup files to the root directory of the system boot partition to avoid The above troubles appear!
Fault 3: After a friend's system updates a driver for XP, XP cannot be started.
Fault Analysis: Obviously there is a problem with the newly installed driver, causing XP to fail to start!
Fault Resolution: The key to solving this fault is to replace the current driver with a stable and reliable driver. If you encounter such a problem under Win98, then you may first think of entering safe mode, and then remove or replace the current driver from safe mode. Can XP's security mode be there? XP's security mode can be called up by pressing Ctrl at startup like Win98. So, is XP's security mode hidden there? In fact, it is very simple to find it. When you start XP, press F8 when the startup progress bar appears, you can call up the XP boot menu and select the safe mode. The problem with entering XP's security mode is simple. The quickest and easiest way is to use Windows XP's system restore to restore the system to its normal state. Of course, you can also use the old method of eliminating such problems under Win98, I think everyone can cope, here is no more details!
Failure prevention: XP startup failure caused by using less stable XP driver is more common. It is recommended not to be too fashionable when choosing XP driver. It is best not to choose the latest driver unless you are willing to help test!
Finally, I remind everyone that if you encounter such a fault, don't panic, be sure to calm down, carefully analyze the cause of the fault, find a way to solve the problem, I wish everyone can use windowsXP to fully experience the fun of digital life!
