How to I remove windows but keep Ubuntu?
So basically I started with Windows Vista then decided I want Ubuntu. Now I have Dualboot using both of them, and want to delete Windows without starting over. And because I've tried the USB boot to replace Windows but got an error, that I couldn't find an answer to.
Is it possible at all?
Simplified version: I start with A add B so I got AB now now I want to delete A and only have B
