Linux rescue

Page content

Sometimes you have to repair that damn linux system …


1st: start your linux system with some ISO file, some CD/DVD or via network.

(for e.g.: Systemrescue Linux)

2nd: mount the root disk of your broken system

mount /dev/sdaX /mnt

3rd: activate proc,sys & dev filesystems:

cd /mnt
mount -t proc proc proc/
mount --rbind /sys sys/
mount --rbind /dev dev/

4th: Enter the broken system:

chroot /mnt /bin/bash

NOW do your repairs!

5th: Reinstall the bootloader (just in case …)

grub-install /dev/sda

6th: logout, unmount and reboot …

umount /mnt
