Like Karl said already, it isn't really clear which drive you call "that 
drive", i.e. where you want to reinstall Ubuntu. However I assume, you 
want to reinstall it on the partition where it is right now. I would 
suggest you take a note of the device names for the partitions you have. 
With the command


in a terminal you can find out which partitions are in use now. The device 
names are in those lines which start with "/dev/<something>". Especially 
the device where the system is installed now should be in the first line. 
Then during the installation select manual partitioning (not sure what it 
is really called - I don't install Ubuntu every day). Then select the 
device where you want to install Ubuntu. The installer will not format 
any other partitions unless you select the format option for those 

Now, the paragraph above may be a bit unclear also. If you aren't really 
sure, what I meant with it, please provide the device names for the 
partitions in your machine and tell us where you want to install Ubuntu 
and which partitions should be left untouched. Then it is easier to tell 
you what to do.
