if I change I try to PXE boot ubuntu 10.04,it shows runlevel is unknown

initctl list:

mountall-net stop/waiting
rc stop/waiting
rsyslog start/running
test stop/waiting
tty4 stop/waiting

tty1 stop/waiting
udevmonitor stop/waiting
dmesg stop/waiting
network-interface-security start/running
procps stop/waiting
tty6 stop/waiting
ttyS0 stop/waiting

I do a little change in /etc/init/rc-sysinit.conf

from
start on filesystem and net-device-up IFACE=lo

to
start on filesystem

runlevel is N 2

is there any final solution for this issue?
