This step is shown only if an existing GNU/Linux partition is found on your machine.
DrakX now needs to know if you want to install from scratch or to upgrade your existing Mandriva Linux system:
This installation type simply updates the packages currently installed on your Mandriva Linux system. Your current partitioning scheme and user data won't be altered. Most of the other configuration steps remain available and are similar to a standard installation.
For
the most part, this completely wipes out the old
system. However, depending on your partitioning scheme, you
can prevent some of your existing data (particularly
/home
directories) from being
overwritten.
