Question:
I burned the latest x64 image from the GNOME Shell LiveCD but how to use it now.
Just boot it or? And wont I lose my current install of Opensuse 11.4?
Just boot it. Don’t choose to “install” – and then you won’t lose you current installation on the hard drive. Live CDs are a utility, a curiosity, a tool, etc, but not to be confused with a permanent operating system.
