Linux boot systems can all be configured to show a menu that lets you select and boot any of the displayed OSes. My distro (Fedora) keeps the last three kernels to be installed in the menu. Its normal to define a default OS, which automatically boots after giving you a few seconds to select a different one. The topmost item in the list is the usual default but this can be overridden. If this is NOT how your boot system is operating, ask how to fix it on the Ubuntu forums. Martin
