Azimout's Linux weblog

To install/remove packages (or modify in general) on a Linux system that is unbootable, you can boot with a LiveCD, mount the underlying system’s root partition and then chroot to that mount point. After that, any commands will be run on the underlying system, rather than on the LiveCD…

Some actions (e.g. installing grub) require also the devfs, procfs and sysfs filesystems, so before chrooting, remember to also:

  • sudo mount -o bind /dev /mnt/dev
  • sudo mount -t proc none /mnt/proc
  • sudo mount -t sysfs none /mnt/sys

(I assume here that the root partition was mounted under /mnt)

Update 01.10.2010: if you’re using dhcp, networking will not work because /etc/resolv.conf will be empty. Add “nameserver” to that file
