vfat file systems.
Accessing the Installed System
If you need to access the installed system from the rescue system to, for example,
modify the boot loader configuration, or to execute a hardware configuration utility,
you need to do this in a "change root" environment.
To set up a "change root" environment based on the installed system, proceed as fol-
lows:
1 First mount the root partition from the installed system and the device file system:
mount /dev/sda6 /mnt
mount --bind /dev /mnt/dev
2 Now you can "change root" into the new environment:
chroot /mnt
3 Then mount /proc and /sys:
mount /proc
mount /sys
4 Finally, mount the remaining partitions from the installed system:
mount -a
5 Now you have access to the installed system. Before rebooting the system, un-
mount the partitions with umount -a and leave the "change root" environment
with exit.
