Short answer:

  1. Make sure all your data is backed up.
  2. Are you absolutely sure there isn't any data you need on the Windows partition?
  3. Boot from an Ubuntu live CD/USB and run GParted (System / Administration / Partition Editor). Remove the Windows partition and resize the Linux partition to use the whole drive.
  4. Reboot into Linux and run sudo update-grub.
