How to I load a different version of Ubuntu

[Dallas KD4HNX]

I downloaded both 12.10 and 12.04.2 LTS...  I installed 12.10 and it works but I wanted the LTS version...

If I put in the DVD with the ISO image will it prompt me to blow away the 12.10 version and install the LTS one

What do I need to do?
