Recreating /boot and /boot/efi partition of a broken installation
Raw
boot_fix_linux.md

Recreating or fixing the /boot and /boot/efi partition of a broken installation

  • Situations
    • Deleted /boot partition by mistake or intentionally.
    • /boot partition got corrupted
    • Failed update
  • Commands are for an Arch-linux installation, so you might need to find the equivalent for other distros.

After chroot-ing into the installation through a live iso. (See my other gist)

pacman -S grub

# mkdir /boot/efi [not always required]
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=GRUB
grub-mkconfig -o /boot/grub/grub.cfg

pacman -S linux linux-lts
mkinitcpio -p linux
