No, probably not  If it is not clear at that point (before you click
continue) which disk it is going to install on then click on Something
Else (I think that is what it says) when you are asked where you want
to install and you will be shown all the partitions available and will
be able to select which one you want to install on.  If you just want
to install over the top of the 12.04 partition then select it and
select '/' as the mount point.  If you want to keep the data in your
home folder on 12.04 (assuming it is not a separate partition) then do
*not* select 'format'.  If you want to overwrite your home folder then
do select format.  Either way of course make sure you have backed up
anything important first of course.

Of course you could just disconnect the second disc and then tell it
to use the whole disc and there will be no danger of overwriting the
one you have removed.
