Windows XP boot troubleshooting

Win XP has optimized the system as a whole, so the boot speed is not only much faster than Win 2000, but also much faster than Win 9x. However, many users find that Win XP cannot boot after upgrading or after installing other drivers. How to solve such problems? Computer repair tool BOIS fault Fault 1: The friend's computer is equipped with Win 98 and Windows XP. After using it for a while, reinstall Win98, causing Windows XP to fail to start. Motherboard failure Failure analysis: The reinstalled Win98 will be overwritten by the XP startup file in the root directory of the system boot partition, causing XP to fail to start. Solution of the fault: Knowing the cause, the fault will be solved. The key to solving the problem is to reinstall XP OS_Loader (Hint: Win NT/2000 and Win XP bootloader), put the XP installation disk into the CD-ROM drive, and then enter the XP installer, after it copies the installer to your Stop immediately after the disk, then go back to the root directory 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 of the fault: In fact, such a fault can not occur, as long as the Win98 boot disk is used when reinstalling Win98, then the "Win 98 installation" will appear on the startup screen. Select an option. You can install it with confidence! Fault 2: The friend's computer was originally started by Win 98 and XP. After that, Win 98 was not stable enough, and it was upgraded to Win2000, which caused Windows XP to fail to start. Fault Analysis: Upgrade Win 98 to Win 2000, Win 2000 rewrote ntldr, ntdetect. Com, boot. Ini these three important startup files, Win 2000 can not boot XP, causing XP can not start. Solution of the fault: The key to solve the fault is to boot Win2000 with WinXP (Note: Win 2000 can't boot XP, but XP can boot Win 2000!), that is, use XP's ntldr, ntdetect. The com file starts the system and lets XP boot Win2000. To solve the problem: first start Win 98, 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 boot entry of the file XP to “de?fault=”, 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, set it to read-only, hidden properties to the root directory of the system boot partition! Another way 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! Prevention of failure: Just back up the three startup files before the upgrade, and then install Win 2000 from the Win 98 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. Trouble!
