Make grub hidden again

[grumpey (Joe)]

To adjust the timeout:

After the last update, GRUB timeout was set to 5 seconds

It is unusual for an update to change grub defaults. You will likely have to fix that manually. edit /etc/default/grub and edit the line GRUB_TIMEOUT=0 to GRUB_TIMEOUT=5 Afterwards, do a grub2-mkconfig -o /boot/grub2/grub.cfg(if your system is EFI-based) and reboot … See also Working with the GRUB 2 Boot Loader :: Fedora Docs

AFAIK you still need to be holding down shift and/or hitting esc or F8 to get the menu.
