Getting rid of windows 10 from dual boot

Question

How can I completely uninstall Windows 10 from a dual boot with Ubuntu?

Answer 1

When you are running Ubuntu, you can easily destroy the whole Windows partition and repair the grub menu. First, install "gparted"

sudo apt-get install gparted

Open it, and find your Windows partition. Now you can simply delete it or reformat it in order to use it from Ubuntu (if you wanted to extend your actual Ubuntu partition, you would have to do it from USB/liveCD).

After confirming changes, open terminal (ctrl+alt+t) and type

sudo update-grub

in order to restore grub.

Enjoy!

Answer 2

1. You need to boot using live USB/DVD.
2. Once booted in, try to use gparted to delete the Windows partition.
3. I will say don't delete the recovery partition in case you change your mind in future to reinstall Windows.
4. Then resize your Linux partition and take away the left out place of Windows.
5. Apply the changes.
6. Then sudo update-grub

You should be good to go.
