Look, leave like 20GB of your HD unallocated (this is there is no partition un that part of the HD). Then start Kubuntu's installation and select the Unallocated part of the disk (using the manual partition setup when asked). Then choose the option to automatically set up partitions in the unallocated space. This will most likely create a 1GB swap partition and a 19GB ext3 format partition. Feel free to use less space if you need it for windows, but you will find yourself installing lots of software, so you'll maybe need at least 10GB in the "working" partition (no the swap one). However, the default installation dowsn't take more than 1GB, iirc.
