Changing partition setup

[tezza]

My master hard drive is dual boot, XP (ntfs)and Linux (ext3)
and I would now like to delete the Windows partition and
increase the Linux partiton. I would be grateful if somebody
would advise if this is possible and if so how to do it.

gparted can do this for you.

if you dont have it installed
'sudo apt-get update && sudo apt-get install gparted'

hope this helps
