I changed the /etc/inittab in my red hat but deleted the ID 5 , left it empty now i cannot load the system, it displays
INIT: No more processes in this runlevel

Please help me!

I think if you copy your inittab here it'd be easier to see what went wrong, they're pretty standard. Have you changed anything else in your system (deleted any files etc)?

PS. If you don't have access to your system, try using a live CD or log in in single user mode

on the boot menu screen, assuming you're using grub, hit esc to enter the menu, and then e to edit the current config, or just e if you see it by default, then add "3" to the line, and b for boot. this will bot you into runlevel 3 instead of 5, letting you fix whatever you need to.

OUCH!!!

The only RH distro I have run is Fedora so I don't know if this will work or not.

1.] Start your box up and as soon as you see the boot selection come u asking which kernel to boot, hit escape or anything to stop the auto selection.
2.] try and navigate to the kernel you normally boot to and strike e, enter and then 3 key to try and get the box to boot to run level 3.
3.] If this works, you should now be able to access a terminal as root.
It will just be a black screen with bash-3.1$ showing.
If so, as root, nano /etc/inittab, enter and change your run level back to 5.
In nano to save the change,,, ctrl x enter,,, y enter.

If this way doesn't get you to a terminal, hopefully someone else here knows how to boot to a terminal in RH and help you.
If not, try checking the fedora wiki or forum and most definitely someone there knows how.

Edit: Sorry for the double post. Didn't know we were both answering the question with the same response.

I just deleted the 5 and saved it and restrated

Hi All,
I'm using RedHat Linux 9. I've made some changes in 'inittab'
file. The changes are as follow:

id::initdefauult:

Here I've just omitted the runlevel number in the hope that
it would ask the user what runlevel to enter after booting.
This line was originally like this -> 'id:5:initdefault:'.
But after booting it automatically entered into runlevel 9 and
displayed a message like 'no operation is specified in this
runlevel ' and then stoped execution. From here neither could I
login nor I could change the inittab file. My bootloader is
'grub'.

Can anybody help me out to solve this problem ?

A start would be to use a good title to describe the problem,

Yes, we already have... have you tried?
