This video is part 2 of 3 for the Linux boot process. If you missed part 1, please see the link below. Video 1: Stage 1: BIOS and UEFI | CompTIA Linux+ Prep - https://youtu.be/Az9nO9KlhJg Today I will cover Stage 2: GRUB and GRUB2. I will cover what they are, the differences, and demonstrate where boot files are on Ubuntu and CentOS. GRUB: Grand Unified Bootloader GRUB: the way a computer transitions from BIOS or UEFI boot up conditions to the OS GRUB: Older and limited Hard to modify the configuration files - /etc/default Display boot menu at startup Boot files: menu.lst or grub.conf GRUB2: Newer and most used More customizable config files - /etc/default Hidden boot menu at startup More boot methods: ISO, USB, UUID, etc Boot files: grub.cfg Ubuntu Commands: Boot folder: cd /boot/grub GRUB Config file: cat /etc/default/grub Make changes: sudo update-grub CentOS boot folder: cd /boot GRUB Config File: cd /etc/default Exit Vi: :q!
