Out of the 320gb of hard drive space my computer came with, only 33 GB were partitioned to Ubuntu, with the rest of the space (288 GB or so) going to windows NTFS. Of those 33 GB, 11 GB are allocated to the system and 20 GB to the home directory; 2 more GB are swap and one last gigabyte is unallocated.
As I currently stand, I am running 13.04 and my root partition is 93% full with very little on my desktop. In order to repartition my disk, I'll need to upgrade to 13.10 as I can't find a 13.04 ISO on the Ubuntu website; once I do that I'll boot into a live USB system and repartition from there.
Is there some way I can just delete the Windows partition and reallocate? I don't think I can, but I'm asking anyway.
Also, can I reassign the unallocated space (all 1 GB of it) to my filesystem?
