Managing the System Bootloader in RHEL 8

The bootloader is the first software program that executes when the system starts, and it's in control until it passes it to the kernel, which brings up the rest of the operating system. The GRUB bootloader in RHEL is highly configurable. In this hands-on lab, we will work with the system bootloader on RHEL 8. *This course is not approved or sponsored by Red Hat.*
