I want to delay the boot time on one of my 2 cluster nodes. From the documentation all I have to do is change the "Time to display list of Operating System" within the Startup and Recovery options. The default is 30 seconds. I am confused, how does that delay the boot time if only one operating system is listed on the server? It's my understanding this setting is when there is more than one operating sytem listed. So How do I delay the boot up time?
