Happening to me on HP EliteBook 8460p UEFI install and Ubuntu MATE 20.04! Tried all sorts of GRUB_TIMEOUT and GRUB_TIMEOUT_STYLE settings to no avail.
GRUB menu *IS* actually there but it won't show up: it just freezes on a black screen until the timeout expires or a key is pressed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1836934 Title: eoan boot hides grub menu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1836934/+subscriptions -- ubuntu-bugs mailing list email@example.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
