Recently I changed for Linux Ubuntu 12.04, I left Windows and I want now to get all my hard disk space, cause when I formatted my PC installing Ubuntu 12.04, I only gave Ubuntu
23.0 GB and now I'm only using Ubuntu 12.04 and I want to get all my hard disk space (Before called Windows; hard drive C and Hard Drive D).
How can I do this? Do I have to use terminal? Thanks .
