1  This presents a way to repair a damaged HardenedBSD system with the installation media (Live-CD). In the example, the **ZFS** file system is used.
 2  
 3  1. Download the [HardenedBSD installation media](https://mirror.laylo.io/pub/hardenedbsd/).
 4  1. Boot on this and select "Live CD" (the username is "root" without password).
 5  1. If you want to choice other keybord, use `kbdmap` command.
 6  
 7  1. You probably need to enable DHCP on your network card via the command: `dhclient em0`
 8  
 9  1. You may need to know your partitions: `gpart show`
10  
11  1. Run zpool import to get name of zpool (probably zroot): `zpool import`
12  
13  1. Create a mountpoint for zpool: `mkdir -p /tmp/zroot`
14  
15  1. Import zpool: `zpool import -fR /tmp/zroot zroot`
16  
17  1. Create a mountpoint for zfs /: `mkdir /tmp/root`
18  
19  1. Mount / (the directories will now be available in /tmp/root): `mount -t zfs zroot/ROOT/default /tmp/root`
20  
21  1. Repair HardenedBSD ([hash link for hbsd-update](http://updates.hardenedbsd.org/pub/HardenedBSD/updates/hardened/)):
22  ```
23  chroot /tmp/root /bin/sh
24  hbsd-update -d -V -U -v hbsd-v1x0000x-UPDATE-HASH
25  exit
26  ```
27  
28  Make changes or save your stuff as needed export zpool: `zpool export zroot`
29  
30  Boot normally.
