Title: Ubuntu wont boot up
Post by: flyingfisch on December 08, 2011, 12:02:27 pm

SYSTEM INFO:
Windows XP pro and Ubuntu 11.10 dual boot
nVidia Graphics card
emachines T2482


OK, so today, i boot up my computer and i get the grub 2 boot menu as usual. I select Ubuntu and i get a black screen with a white cursor blinking in the corner. So i booted up my LiveCD and searched for the problem on the internet. I found that since I have nVidia graphics card, I can edit the boot script line that says:

Code: [Select]

splash quiet quiet splash

(idk if that was the exact code, but it was similar)

and replaced it with:

Code: [Select]

nomodeset

It showed text now and got hung up at:

Code: [Select]

Begin: Running /scripts/init-bottom ... done

Does anyone know whats going on? (it was working for a few days before this happened)

First of all, does it stay like that if you wait a bit?
It *can* be that its just busy checking your harddisk for errors, so that takes a little while.

Also, editing the file while not help right away, you need to use update-grub after that. But this isn't so easy when you are on the live-cd.
If it doesn't boot after some time, try if you can boot with the recovery option. Just notify us when its that far.

I can boot with the recovery option. Here is the thread i made at ubuntuforums.org: http://ubuntuforums.org/showthread.php?t=1892645

No one has replied to it. It has all my error codes though.

If you press ctrl-alt-f2 while it shows those messages, does it drop you to a shell?

No it does not. I have rebooted twice and tried and it still wont drop me to shell. Like i said in the post, ctrl+alt+del doesn't force reboot either

Very very strange.
What happens if you go to recovery, wait for the menu and choose continue?

continue? all i see is:

Code: [Select]

Recovery  Menu (limited read-only menu)

resume     Resume normal boot
fsck         Check all file systems (will exit read-only mode)
remount    Remount / read/write and mount all other file systems
root         Drop to root shell prompt

<Ok>                        <Cancel>

Happbob: I did reinstall grub.

I renamed xorg.conf to xorg.conf.bak

Right now its displaying 3 NAK bailout messages. I'm gonna let it sit there for a while while i eat dinner.

OK, i turned it off [the computer] cuz it seems to be frozen again. :/

It seems like it might be a kernel problem.

What i want to do now is reinstall ubuntu but keep things such as personal settings. Does anyone know how to go about this?

Sure, when I'll get home. I'm at school right now and I'm supposed to work.

Post by: flyingfisch on December 08, 2011, 05:20:10 pm

oh, ok. Maybe i wont need help after all. Here is what i propose to do:

1. Boot into liveCD
2. in terminal type:

Code: [Select]

sudo nautilus

3. Ctrl+H to show all files and folders
4. Move all files from liveCD to linux partition except /home and /usr

However, I woud like to know if there is another way to do it using the installer on the liveCD or something similar.
