I have experienced a non-appearing grub once before and it was sometime during the 3.x series. I ignored it and edited grub because I was in a hurry and the system still booted. It was an older Dell. If my memory serves correctly (which is old and tired) It had something to do with out of series (deprecated) update issue and grub timeout needing to be above 0.
