If the Grub is corrupted and you are not able to boot from your existing Archlinux system you will need an Archlinux installation CD or something similar on a bootable USB stick to install a new Grub. In this case the Grub is on /dev/sda and after booting from CD fdisk -l
will show up the following partitions:
Device Boot Start End Sectors Size Id Type
/dev/sda1 * 2048 3774875647 3774873600 1,8T 83 Linux /dev/sda2 3774875648 3907029167 132153520 63G 82 Linux swap / Solaris In this case the complete Linux filesystem is on /dev/sda1. To replace the corrupted Grub we will need the following steps:
mount /dev/sda1 /mnt
arch-chroot /mnt grub-mkconfig -o /boot/grub/grub.cfg grub-install /dev/sda exit umount /dev/sda1 After rebooting the system the Grub should be fine. | ||||||||||||||
