Edit file in Grub

I have RH9 and it loads into init 5 by default but im having problems with video drivers and it freezes when it loads.

I need to change intittab from 5 to 3 and as i understand the only way to do it is in grub.

Someone please advise. If there's any other way to fix this problem feel free to comment.

there are plenty of ways to change. in x normal x session run "init 3" as root for example. you would do it via grub by pressing e to edit and adding "init 3" to the command line before you run it.

I cant load X, i have to do it in grub.
in grub i have the following load line:

kerenel /boot/vmlinuz-2.4.20-8 ro root=LABEL=/

where do i add init 3 line? when i press enter it exits the edit. How do i do it?

anywhere, the end will be fine. grub should show you instructinos on the screen at the time.

actually i have the following lines in grub:

root (hd0,1)
kernek /boot/vmlinuz-2.4.20-8 ro root=LABEL=/
initrd /boot/initrd-2.4.20-8.img

I tried adding another line:
init 3

but when i boot it says unrecognized command

I think it may be init=3.
The online manual may help you.

Jesus christ this guy is a newbie and you idiots are telling him to f@ck with his grub file, yeah thats smart, here is an appifany, change the line in your /etc/inittab from:
id:5:initdefault:
to
id:3:initdefault:

and if your wondering how to boot up enogh to be able to change it, at the grub load sceen, hit e, then edit the line:
kernel /vmlinuz-2.4.20-8 ro root=LABEL=/ hdc=ide-scsi
to
kernel /vmlinuz-2.4.20-8 ro root=LABEL=/ hdc=ide-scsi s
then boot to singe and edit the above mentioned /etc/innittab file.

To boot into Single User mode

Add the word "single" at the end of the kernel line and press ENTER.

You will be returned to the GRUB screen with the kernel information. Press the [b] key to boot the system.

Thank you, emence, it worked

What does "s" mean anyway? How come it didnt load up to the point when it asks me for user/pass?

Mathieu · 07-11-2003, 01:14 PM

s means Single User mode.

Single User mode (init 1 or runlevel 1) is similar to Safe Mode in Windows. It never requires a username and password.

Use it to fix problems with your system, to change your root password if you forget it, etc...
