Booting Single-User Mode

You may be able to boot single-user mode directly. If your system
boots, but does not allow you to log in when it has completed booting,
try single-user mode.

If you are using GRUB, use the following steps to boot into
single-user mode:

1. If you have a GRUB password configured, type p
   and enter the password.

2. Select Red Hat Linux with the version of the kernel
   that you wish to boot and type e for edit. You
   will be presented with a list of items in the configuration file
   for the title you just selected.

3. Select the line that starts with
   kernel and type
   e to edit the line.

4. Go to the end of the line and type single
   as a separate word (press the [Spacebar] and then
   type single). Press [Enter]
   to exit edit mode.

5. Back at the GRUB screen, type b to boot into
   single user mode.
