basically i rebooted my laptop one the other day, and it kept saying the windows files were currupted, etc. to cut a long story short, ive quite possibly lost all my data only have a 2gb usb stick, and the ubuntu live cd was a bit slow, so decided to install xbuntu. it all works fine, except theres no free disc space, it wont even let me remove app's because of the lack of space. i want to install flash and a few other things just to tide me over, but i cant. it there anyway to make some free space?
