Yes, why not display the Grub menu? Whether any text is displayed or not, there still needs to be a long enough pause that the user has time to press a key. Not displaying any text at all would make it harder to understand that the time to press that key is now. Many people won't even understand that they have an opportunity to press a key. If the menu is displayed, it takes only a few seconds to understand that there is a choice and a countdown, and hopefully most people will quickly discover that pressing a key stops the countdown. Thus five seconds is a long enough pause. If some text like "Press Esc now to choose which operating system to boot." would be displayed, then the pause would need to be long enough for the user to read and understand the instruction and then reach for the right key – and the terser the text is made the harder it will be to understand. I estimate that at least 15 seconds would be needed. Adding "Press Enter to save a few seconds." would make it even more text to read and understand. Björn Persson
