How To Boot Into Rescue Mode Or Emergency Mode In Ubuntu 18.04

As you might already know, Runlevels are replaced with Systemd targets in many recent Linux distributions like RHEL 7 and Ubuntu 16.04 LTS. The brief tutorial linked to below shows how to boot into rescue mode and/or emergency mode. The guide is tested in Ubuntu 18.04 LTS, however, the steps given would work on most Linux distributions that use Systemd as default service manager.

The rescue mode is equivalent to single user mode in Linux distributions that uses SysV as the default service manager. In rescue mode, all local filesystems will be mounted, only some important services will be started. However, no normal services (E.g network services) won’t be started. The rescue mode is helpful in situations where the system can’t boot normally.

In contrast to the rescue mode, nothing is started in the emergency mode. No services are started, no mount points mounted, no sockets established, nothing. All you will have is just a raw shell. Emergency mode is suitable for debugging purposes.
