Easily uninstall multiple operating systems (2)

2. If the system is installed on the C drive, you need to use the Win2000/XP/2003 installation CD. After booting using the installation CD, press Enter to "Start Installation", press F8 to enter the interface for selecting the installation partition, select the C drive, press D to delete the C drive, and then press C to rebuild a C drive. Of course, you can also use the famous PQMagic, System Command's fellow division Partition Command to delete the C drive and rebuild the C drive. I recommend using the Win2000/XP/2003 installation CD to delete the C drive and rebuild the C drive.

3. After deleting the C drive, use the corresponding installation CD of the remaining system to boot into the "Recovery Console" for repair (if it is multi-system, use the installation CD of the highest version of the system).

Take the repair WinXP system as an example. Press the “R” key to enter the “Failure Recovery Console” interface. The system will search for the installed WinXP system files, then display the search results and ask “Login To which WinXP installation", select WinXP installation directory and press Enter, the system will ask "admin password", then type the administrator password set when WinXP is installed, the system will search for the installed WinXP system file, when it appears WinXP system file installation directory, such as D: \\ Windows, you need to enter the repair command Fixboot to write the new partition boot sector to the specified partition, the latter parameter is the disk drive letter to be written to the boot sector, here fill in C :, enter. After the repair is complete, type Exit to exit and restart it successfully.

Second, Linux and Windows can choose one of them

2.1 Uninstall Linux

1. If you use Linux boot manager Lilo for multi-system boot, then delete Linux method Yes: Enter DOS mode, execute fdisk /mbr, remove 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 if the disk where WinNT is located is Active. If not, the instructions have been modified for Lilo. You must use PQMagic and other tools to change it back, otherwise it will not start.

2. If you use the boot tool such as OsLoader, the first boot is Windows, then the method of removing Linux is simple, remove the Linux option in the multi-OS boot tool, and then delete the partition where Linux is located. .

3. It is easier to remove one of the multiple Linux systems, directly modify LiLo, remove the option to uninstall, use the Linux disk management tool to delete the partition where Linux is to be uninstalled and reuse it. .

4. If you have multiple Windows installed, running the fdisk /mbr command in this way will overwrite the Windows multi-boot menu so that the machine can only boot from the default main operating system. In order to repair the Windows multi-boot menu, we also need to use the Win2000/XP/2003 installation CD to boot into the "Recovery Console", log in to the last installed system, enter fixmbr to write a new master boot record to the hard disk, and Press Enter. The system prompts that there is already an illegal startup record, so don't bother, just confirm to continue. Restart, the familiar Windows boot menu will be back.

2.2 Uninstalling Windows

1. If multiple operating systems use OsLoader to boot, you can upgrade the Linux system, reinstall Lilo, install Lilo into MBR, reboot and enter Linux, delete The directory or partition where Windows is located.

2. If you use Lilo to boot, delete the Windows method: enter Linux, modify the Lilo option, remove the Windows boot option in Lilo, and then re-write Lilo into the main boot sector, and finally Feel free to dispose of the partition where Windows is located.

This is an example of deleting WinXP under edora Core 2. Let's open /boot/grub/grub.conf with a text editor such as vi.

# vi /boot/grub/grub.conf

Then delete the following statement:

title Windows XP

3. If After removing WinXP, only Linux is left, you can also modify the time that the boot menu stays. Change the "timeout=10" statement to "timeout=0". This allows you to boot into Linux immediately without the boot menu. Do not modify this line if it is still multi-system after deletion.

In addition to this, we can also use the graphical interface to modify the startup properties. To do this, click the Main Menu → System Settings → Boot Loader menu item to open the Boot Configuration dialog box, make sure the Fedora Core option is selected, and set the timeout to 1 second.
