How to boot Fedora with GRUB2 bootloader?
1 The grub2-mkconfig command creates a new configuration based on the currently running system. 2 The configuration format is changing with time, and a new configuration file can become slightly incompatible with the older versions of the bootloader. 3 In Fedora, it is generally safe to edit /boot/grub2/grub.cfg manually.
GRUB 2 scripts search the user’s computer and build a boot menu based on what operating systems the scripts find. To reflect the latest system boot options, the boot menu is rebuilt automatically when the kernel is updated or a new kernel is added.
When to use / etc / default / Grub in GRUB 2?
The /etc/default/grub file is used by the grub2-mkconfig tool, which is used by anaconda when creating grub.cfg during the installation process, and can be used in the event of a system failure, for example if the boot loader configurations need to be recreated.
Among various code snippets and directives, the grub.cfg configuration file contains one or more menuentry blocks, each representing a single GRUB 2 boot menu entry. These blocks always start with the menuentry keyword followed by a title, list of options, and an opening curly bracket, and end with a closing curly bracket.

What is the role of bootloader in Fedora?
A bootloader is the first software program that runs when a computer starts. It is responsible for loading and transferring control to the operating system kernel. In Fedora, the kernel is Linux.
