Depending on the configuration of your laptop, you can boot a Live CD, or a bootable USB stick, and then use the running OS to mount your data partition. With the partition that holds your data mounted, you can copy your data to another USB stick or a connected hard drive, or whatever you need to do.

Whoa! If the first thing you need to do is copy data off that hard drive, then you don't choose "Install" you choose "Try Kubuntu".

Once the desktop comes up, pop open konsole and do

sudo fdisk -l

which will show the partitions on your hard drive. Hopefully you know where your data are -- let's say you previously had a single large partition with Kubuntu on it, /dev/sda1, formatted ext4. So you would do this:

sudo mkdir -p /mnt/mystuff

sudo mount -t ext4 /dev/sda1 /mnt/mystuff

Now your partition is mounted. using dolphin you can browse to /mnt/mystuff, and find /home/jethro and there are all your data. Insert your USB storage device, observe the notifier pop it up, choose "open in Dolphin", and now you can simply copy and paste your data from /home/jethro on the mounted internal drive to the USB storage device.

OK?
