partitioning

I have ubuntu 13.04 dual booting wit MS windows. It is a 32 bit version but the pc is a 64 bit.

When I use the 64 bit install DVD it sees the two main partitions and gives several options but I can't find how to replace the ubuntu 32 with the 64 version without chopping the hard drive into little pieces or formatting the whole drive .

I don't want to to do this and don't recognise any of the partitions shown when I go to the "do something else" menu.
