To delete windows from my laptop(with ubuntu installed already)
I installed unbuntu a few weeks ago, and now I completely don't wan't to go back to windows anymore. Ubuntu is so cool and useful to me.
I want to delete windows from my laptop. I have partition C: windows, and D: data in windows. And I can see them from ubuntu.
How can I delete windows so that I can let ubuntu have the whole disk partition? (I already had the windows useful data backed up)
