Ok, then I just made it 50 seconds.

Code:
[root@localhost john]# cat /etc/default/grub
GRUB_TIMEOUT=50
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="resume=/dev/mapper/fedora-swap rd.lvm.lv=fedora/root rd.lvm.lv=fedora/swap rhgb quiet"
GRUB_DISABLE_RECOVERY="true"
[root@localhost john]#
Code:
[root@localhost john]# grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
