The method of uninstalling any Win2000/XP/2003 multi-system is simple.

1. If the system is installed on a non-C drive, you can delete it directly, and then modify the Boot.ini file, that is, "Multi (0) disk (0) rdisk (0) partition (2) \ Windows =" The system name you deleted, for example, you deleted Windows 2000, so here is Windows 2000 Professional "/.

2. If the system is installed on drive C, you need to use the installation CD of Win2000/XP/2003. After the installation CD is started, press enter to start the installation, press F8 to enter the interface of selecting installation partition, select disk C, press D to delete disk C, and then press C to rebuild a disk C. Of course, you can also use the famous PQMagic, classmates commanded by the system, partition commands, etc. Delete and rebuild drive c. I recommend using the installation CD of Win2000/XP/2003 to delete and rebuild the C disk.

3. After deleting disk C, use the installation disk corresponding to the remaining systems to start and enter the "Recovery Console" for repair (if there are multiple systems, use the installation disk with the highest version of the system).

Take repairing WinXP system as an example, press "R" key to enter the "Recovery Console" interface. At this time, the system will search for the installed WinXP system files, then display the search results and ask "Which WinXP installation should I log in to", select the installation directory of WinXP and press enter, and the system will ask for "administrator password" again, and then enter the administrator password set when installing WinXP. At this point, the system will search for the installed WinXP system files. When the installation directory of WinXP system files appears, such as D: \ Windows, you need to enter the repair command Fixboot to write the boot sector of the new partition into the specified partition. The following parameters are the disk drive letter to which the boot sector is to be written. Here, fill in C: and press Enter. After the repair is completed, type Exit to exit, and the repair is successful after restarting.

Choose between Linux and Windows.

Uninstall Linux

1. If the boot manager Lilo of Linux is used for multi-system boot, the way to delete Linux is to enter DOS mode, execute fdisk /mbr, delete the Lilo code placed in the main boot sector, and then use the partition tool to delete the partition where Linux is located.

One more thing to do is to check whether the disk where WinNT is located is active. If it is not, it means that it has been modified for Lilo, and it must be changed back with tools such as PQMagic, otherwise it cannot be started.

2. If you use boot tools such as OsLoader to start Windows first, the method of deleting Linux is very simple. Remove the Linux option from the boot tools of multiple operating systems, and then delete the partition where Linux is located.

3. It is easier to uninstall one of multiple Linux systems. Modify LiLo directly, remove the uninstall option, delete the partition to uninstall Linux with Linux disk management tools, and reuse it.

4. If you have multiple Windows installations, running the fdisk /mbr command in this way will override the Windows multi-boot menu, so that the computer can only boot from the default main operating system. In order to repair the multi-boot menu of Windows, we also need to use the installation CD of Win2000/XP/2003 to boot into the "recovery console", log in to the last installed system, enter fixmbr, write a new master boot record to the hard disk, and press enter. The system prompts that there is an illegal startup record, so just ignore it and confirm to continue the operation. Restart, and the familiar Windows startup menu is back.

Uninstall Windows

1. If multiple operating systems are booted through OsLoader, you can upgrade the Linux system, reinstall Lilo once, install Lilo in MBR, and delete the directory or partition where Windows is located after restarting Linux.

2. If you boot with Lilo, the way to delete Windows is to enter Linux, modify the options of Lilo, remove the startup options of Windows in Lilo, and then write Lilo into the main boot sector. Finally, you can dispose of the partition where Windows is located at will.

Take deleting WinXP under Fedora Core 2 as an example, and open /boot/grub/grub.conf with a text editor such as vi.

# vi /boot/grub/grub.conf

Then delete the following sentence fragment:

Title Windows XP

3. If only Linux is left after deleting WinXP, you can also modify the stay time of the startup menu, that is, change the statement "timeout= 10" to "timeout=0". In this way, the boot can enter Linux immediately without starting the menu. If there are still multiple systems after deletion, please do not modify this line.
