I am on Fedora 25. The other day did a few system upgrades to keep everything up to date. Usually on initial bootup I get the Grub menu that appears on screen so I can select which kernel I want to boot into, whether I want to boot into rescue mode and/or whether I want to add any specialized boot options. Suddenly I am not getting that menu anymore. It just boots into some kernel and eventually takes me to the login screen, Any ideas ? I'm not too familiar with GRUB troubleshooting... in the past it always just worked. Has anyobne else experienced this and or anyone familiar with diagnosing the GRUB boot loader ?
