Correctly uninstall Ubuntu on both Windows 7 and Ubuntu systems (hands-on Experiment)

If Ubuntu is not installed in wubi mode, you should be careful when uninstalling Ubuntu, instead of simply deleting the partition where ubuntu is located, otherwise, you will find that your windows system cannot enter. That's because if you write GRUB to MBR when installing Ubuntu, that is,/dev/sda (if the GURB menu appears every time you open the machine, it indicates writing it to MBR ). Then, when you uninstall ubuntu, rewrite the MBR and remove the GURB of ubuntu. Correct methods to delete ubuntu are as follows: Step 1, repair MBR 1. go to win7, download the MbrFix software, and place it in the C: \ windows \ system32 folder. 2. click "start" All Programs "attachment" command prompt 3. enter MbrFix/drive 0 fixmbr/yes 4 in the command prompt. now the MBR has been repaired. After you restart the Computer, you will find that the linux Startup option is no longer available. Go to step 1 of windows and delete Ubuntu under windows 7) right-click a volume and choose Manage from the shortcut menu. Choose DiskManagement from the shortcut menu. There are two non-volume names (the volume name is the drive letter, for example, C:, D:, E :, ...) PrimaryPartition is the Ubuntu partition, and the window color of the main partition is dark blue. One of them is the Swap partition, which is similar to the physical memory size of the machine; the other is the root partition, which is similar to the size you allocated to it. Right-click the two partitions and select DeleteVolume. After the volume is deleted, the color of the partition window turns green and merged into a window. If you do not want to install Ubuntu, you can create extended partitions, format, assign volume labels, and use them for Windows 7. If you want to install Ubuntu, do not perform any operations after you delete the partition.
