For starters, Ubuntu releases are date specific. It's 8.10 and 7.10 (Both October releases).

There is no direct upgrade path from 7.10 to 8.10. You can upgrade form 7.10 to 8.04, either using the Internet or the alternate install CD.

Boot the CD, run the installation program, when you get to the partitioner, choose 'Manual' and point the installer to 7.10's partition.
