Changing Runlevels at Boot Time

2.10. Changing Runlevels at Boot Time

Under Red Hat Enterprise Linux, it is possible to change the default runlevel at boot time.

If using LILO, access the boot: prompt by typing [Ctrl]-[X]. Then type:

linux <runlevel-number>

In this command, replace <runlevel-number> with either the number of the runlevel to boot into (1 through 5), or the words single or emergency.

If using GRUB, follow these steps:

  • In the graphical GRUB boot loader screen, select the Red Hat Enterprise Linux boot label and press [e] to edit it.

  • Arrow down to the kernel line and press [e] to edit it.

  • At the prompt, type the number of the runlevel you wish to boot into (1 through 5), or the words single or emergency and press [Enter].

  • The GRUB screen reappears with the kernel information. Press the [b] key to boot the system.
