Extend the disk using fdisk (after the disk image itself has been extended):

fdisk -u /dev/sda
- Use the option p to print the partition table (you will need the start position later)
- Delete the partition with option d
- Add a new partition with option n
- Create a primary partition with P and give this the partition number 1
- For the first sector, use the start position from step 2
- Use the defaultvalue for the last sector
- Check your changes by printing the partition table again

List all old kernels that can be removed (Debian) :
dpkg -l linux-{image,headers}-* | awk '/^ii/{print $2}' | egrep '[0-9]+\.[0-9]+\.[0-9]+' | grep -v $(uname -r)

Remove them using dpkg --purge :
ie. dpkg --purge linux-headers-3.13.0-86 linux-headers-3.13.0-86-generic linux-image-3.13.0-86-generic linux-image-extra-3.13.0-86-generic

Afterwards run apt-get autoremove (if needed preceded by apt-get -f install).
