Recently I wanted to speed up system boot by decreasing GRUB timeout. I’ve changed it from 5 to 0 seconds so at the moment GRUB doesn’t take 5 seconds before the system boots. It’s a very simple operation:
- Edit GRUB configuration file -
- Rebuild GRUB.
sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
