Chapter 26. Basic System Recovery

When things go wrong, there are ways to fix problems. However, these methods require that you understand the system well. This chapter describes how to boot into rescue mode, single-user mode, and emergency mode, where you can use your own knowledge to repair the system.

26.1. Common Problems

You might need to boot into one of these recovery modes for any of the following reasons:
  • You are unable to boot normally into Red Hat Enterprise Linux (runlevel 3 or 5).
  • You are having hardware or software problems, and you want to get a few important files off of your system's hard drive.
  • You forgot the root password.
