9.8. Changing Runlevels at Boot Time

Under Red Hat Enterprise Linux, it is possible to change the default runlevel at boot time.
To change the runlevel of a single boot session, use the following instructions:
  • When the GRUB menu bypass screen appears at boot time, press any key to enter the GRUB menu (within the first three seconds).
  • Press the a key to append to the kernel command.
  • Add <space> <runlevel> at the end of the boot options line to boot to the desired runlevel. For example, the following entry would initiate a boot process into runlevel 3: 
    grub append> ro root=/dev/VolGroup00/LogVol00 rhgb quiet 3
