After you install Windows Vista, you may find that some applications have some problems in Windows Vista ———— and we strongly stress the reason to check system compatibility before installing Windows Vista--and want to revert the system to a previously used version, such as Windows XP. Anyway, or for other reasons, you want to uninstall Windows Vista, here's a brief introduction to the uninstall method for Windows Vista.
When Windows Vista is the PC's only operating system uninstall
For PCs that only have Windows Vista operating system installed, uninstall is relatively simple, backup important data files such as Word documents, mail, etc., directly to the hard disk partition format can be.
Uninstall when Windows Vista coexists with other operating systems
As we described earlier, Windows Vista uses a different boot Loader for Windows 2000/XP, and after Windows Vista is installed, the boot process of the hard drive is taken over by Windows Boot Manger (bootmgr), so Removing Windows Vista directly from a dual boot/multiple boot system will cause the system to fail when boot loader is lost.
The following example describes the uninstall method for Windows Vista by installing Windows Vista and Windows XP simultaneously in the system and booting into their respective systems in a dual-boot manner.
A simple way to install Windows XP with Windows Vista in different partitions
Log on to Windows XP with an administrator account, right-click the My Computer icon on the desktop, select Manage, select storage => Disk Management in the Computer Management window that pops up, select Windows Vista installation partition, and choose Format in the right-click menu-Of course , if important data is stored in the partition, please back it up in advance, enter "Msconfig" in the Run dialog box, start the System Configuration Utility, and then select "Boot." INI tab, click "Check all the boot paths"; Click "OK" and "apply" when the check is complete, then the system will ask whether to reboot, select "Exit without reboot" Next, look for the following file in the system disk such as C: root directory, and delete it. --you should set the viewing options for the folder first, and you can see system files and hidden files.
Boot (catalog)]
Boot.bak
Bootsect. Bak
If you cannot delete because of insufficient permissions, first let the administrator take ownership of the file or directory and set deletion permissions.
Then restart the computer.
The disadvantage of this approach is that it does not actually completely erase the Windows Vista installation that exists in the system, but in most cases it can guarantee the normal startup and operation of Windows XP.
Complications such as Windows Vista and XP installation on the same partition or multiple boot uninstall
For complex installation scenarios such as multiple launches or the desire to completely clear Windows Vista installation, you will need to use the Windows XP Recovery Console. (For more detailed information and process diagrams please refer to using the Recovery Console to repair Windows)
Enter the BIOS setup PC boot from the CD drive, insert the Windows XP installation CD into the CD drive, and start the system;
When the splash screen for the installation option appears, select "R" to enter the Recovery Console; (Note: If your system requires additional sata/raid drivers, you should first load the appropriate driver by pressing "F6" in the presence of this domain.) )
Select the Windows XP system you want to log on to, and the system will give you a list of the appropriate operating systems and enter the correct serial number.
Enter the administrator password for repair;
Run the "fixboot" command to rewrite the boot information of the system hard disk;
Enter "Exit" to exit the Recovery Console and reboot, at which point the Windows Vista boot loader has been purged from the system.
Start into Windows XP, and if your Windows Vista is installed in a separate partition, you can use Disk Manager to format the partition directly as described above, and for more complex scenarios, such as Windows Vista sharing partitions with other systems, you can direct windows Vista directory or file deletion, such as "Windows", "Users" directory;
Similarly, delete the "Boot" directory and the "Boot.bak", "Bootsect" in the root directory of the system hard disk, as described above. BAK "File and" bootmgr "file, as for the Recycle Bin, can be judged according to the situation whether deleted;
Right-click My Computer, select Properties => Advanced => Startup and failback => settings, check that Windows XP is the default operating system, or set it as default;
Click the Edit button on the page to open the "Boot.ini" file using Notepad to locate the Windows Vista-related settings and delete them one at a time.
For security reasons, you can use "msconfig" to check if a startup item is set up correctly after completing the above steps, and in the System Configuration Utility BOOT, as described in the above procedure. INI page, click "Check all Boot Paths" and "it appears that all Microsoft operating system lines are correct in all Boot.ini"-a rather awkward remark that some of Microsoft's Chinese companies need to be rebuilt according to the standards of primary language teachers. -That's it.
