You did not follow my original mail I guess. I know how to install
Fedora by booting off the Fedora install CD/DVD.

My original query was how to install FC5 on a machine WHILE the same
machine is booted up and running on FC4. For example in Windowsm, we
can start the install process of newer version while running older
version. The install process is invoked manually.

Is there same facility in Fedora too? I have been unable to find so far.
