How to thoroughly uninstall Ubuntu in win7 and Ubuntu Systems

The dual-system uninstalling Ubuntu does not work with fdisk/MBR this time. I will clean it. What's the problem?

So I humbly asked Google for advice. Google is so powerful that I can solve it.

1. Delete the Ubuntu Partition

Find the Ubuntu partition in disk management under Win, right click -- delete volume

Right-click another disk and choose extend volume to merge the previous Ubuntu partition.

2.put mbrfix.exe under the C root directory: http://download.csdn.net/detail/ethan_xue/4280570

3. Create a USB flash drive PE

Windows: http://download.csdn.net/detail/ethan_xue/4280607

I used ultraiso. For details, open the winpe. ISO image and start-Write the hard disk image.

4. restart the computer. At this time, Windows 7 is no longer in. Start from USB and insert a USB flash drive.

5. Enter winpe, CMD -- cd c: -- mbrfix/drive 0 fixmbr/Yes

If no message is displayed, the process is successfully completed.

Restart, win7 is back, and Ubuntu is uninstalled
