install the apps you want to your existing ubuntu install using
the provided install scripts,  (see below)

that will wipe out + replace your ubuntu installation with xubuntu 11.04, not augment it. if your ubuntu boot is fresh out
of the box, maybe it is no trouble to start again from scratch?

fat32? typically it would be ext4 or ext3 unless it was installed
with the "install to bootable usb" method, which is not needed
for a real hard drive.

as per http://wiki.osgeo.org/wiki/Live_GIS_Build#Getting_started

boot into ubuntu,

make sure subversion is installed:
 sudo apt-get install subversion

then fetch the livedvd build scripts:
 svn checkout https://svn.osgeo.org/osgeo/livedvd/gisvm/trunk osgeo_live

cd into the bin dir:
 cd osgeo_live/bin

and either install everything (will take some time!) with
 ./main.sh

or, just the particular project(s) you are interested in:
 ./install_marble.sh

(in the case you just install individual projects, you may need
to take care of prerequisites by running other install scripts
like install_apache2.sh first)


good luck,
