How to Reinstall GRUB (Alternate Method)

In this video, I show you another, better way to reinstall the GRUB bootloader on Linux. Prerequisites: 1. A Linux install media (any GRUB-based distribution with a live ISO should do) THAT'S IT! Commands used in this video: Mount root partition: sudo mount /dev/sdXY /mnt (example: sudo mount /dev/sda3 /mnt) Mount boot partition (if applicable): sudo mount /dev/sdXY /mnt/boot (example: sudo mount /dev/sda2 /mnt/boot) Mount EFI System partition (if applicable): sudo mount /dev/sdXY /mnt/boot/efi (example: sudo mount /dev/sda1 /mnt/boot/efi) Setup "bind" mounts: sudo mount --bind /dev /mnt/dev sudo mount --bind /proc /mnt/proc sudo mount --bind /sys /mnt/sys Chroot into your Linux installation: sudo chroot /mnt Reinstall GRUB (in chroot): grub-install /dev/sdX (example: grub-install /dev/sda) Regenerate GRUB configuration file (in chroot): update-grub Alternate "update-grub" command (for Arch Linux only): grub-mkconfig -o /boot/grub/grub.cfg Exit chroot: exit Join this channel to get access to perks: youtube.com/drewhowdentech/join
