How to remove/delete Ubuntu partition from windows (Windows Dual Boot)

If you've decided that Ubuntu is no longer the right operating system for you, then you might be wondering how to go about deleting it from your system. Removing Ubuntu when it's the only operating system on your computer is fairly straightforward, but things get a little more complicated if you have Windows installed alongside it. Follow this guide to remove Ubuntu either way.

If you don't have a Windows recovery CD or you are constrained to download and burn the ISO files mentioned before, you can use Boot-repair. It is a tool that fixes most boot problems(Windows or Ubuntu). I suggest using a Windows CD if possible.

To use boot repair:

1. Boot from a Ubuntu live CD or USB
2. Type these lines in the terminal one line at a time.

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install boot-repair
      3.  Search for Boot-Repair in the Dash and launch it.


To fix your computer with Boot-repair, simply click the "Recommended Repair" button. Then follow the steps below to remove the Ubuntu Partitions.

To delete the Ubuntu Partitions:

    4.  Go to Start, right click Computer, then select Manage. Then select Disk Management from the sidebar.


        5.  Right-click your Ubuntu partitions and select "Delete". Check before you delete!

       6.  Then, right-click the partition that is on the Left of the free space. Select "Extend Volume". Go through the Wizard and Finish it.

     7.  Done!
