Ubuntu wont boot past black command type screen


hello-

this is my first ever linux system and up until this, ive been really happy with it. i figured out the repositories and the terminal, but now ive gotten to a point that im totally stuck.

when i try to turn on my computer, the load screen comes up and the orange bar doesnt fill at all for about a minute and half or 2. it just sits there. but then the peach screen flashes on for a moment and then im brought to what looks like a command screen. something like safe mode for windows? its all black with white writing and it says-

" udevd[1461]: parse_config_file: cant open '/etc/udev/udef.conf' as config file: invalid argument
udevdtrigger[1463]: parse_config_file: cant open '/etc/udev/udef.conf' as config file: invalid argument

BusyBox v1.1.3 (Debian 1:1.1.3-5ubuntu12) Built-in shell (ash)
enter 'help' for a built in list of commands. "

i tried putting in help but i dont know what any of the commands mean, and none of them say boot, load, log in or anything that looks like it could get my computer past this screen. any help at all would be very, VERY greatly appreciated.

thanks!

Hi,

And welcome to LQ!

And what did you do before that started happening?

Which version of Ubuntu are you using?


Cheers,
Tink

You might be able to find it with:

history | grep sudo

I'm not sure if that will help. It depends on whether or not you are actually logged in as user.

Another way to see it is to look at

/home/<your-user-name>/.bash_history and find the last commands that begin with sudo. You should be able to look at that even if you are in some single user mode.

He's in busybox, I don't think he can get that far.

I've only had this happen to me once, so can you get to /etc/udev/udef.conf on that command line?

Try rebooting and when you see the orange bar, Do Ctrl-Alt-F1 or Ctrl-Alt-F2. I think one of those will give you text showing what is happening. If you can catch the last few lines and the line where it stops, it might give some clues.

It looks like maybe the uuid got changed. That can happen if you install Linux on another partition or maybe for some other reason.

You could edit both the grub menu.lst and /etc/fstab or maybe it would be easier to boot using grub command line and then run 'update-grub' and 'grub-install /dev/sda' where /dev/sda is changed to what your actual drive is.

This should help you use the grub command line:

If you need more info on updating and installing grub, let us know.

Hi, and welcome to our forum!


At this stage, there is little you can do from Busybox to repair the damage...

If you haven't do any work of your own yet (e.g have written some documents) with your ubuntu system, I suggest you put in your CD your Installation disk, and reinstall ubuntu. Of course if you know about partitions and file-systems, you may choose to not format the partition where your /home directory resides (and keeping the same filesystem as before)... This way you wont lose any work ...

Hi,

vasmakk may be right. However, before going that far, at least try this:

Reboot, and when you see "Grub loading...", press ESC, then select Recovery Mode. After a few lines of text, you'll see a menu. Select "xfix", then "Normal Boot".

I've recovered from a lot of screw-ups that way.

Cheers
