When there are no boot entries to delete, the boot manager was prompting the user to select an entry to delete. This fix prints a message to let the user know that he is trying delete boot entry when there are none. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12405 6f19259b-4bc3-4df7-8a09-765794883524
