I messed with Plymouth and now I'm paying for it...

So if I run 'update-grub' in the live CD of ubuntu, it would work for my installed version of Ubuntu?

You would have to give me the output of
the (sudo fdisk -l) (earlier post) so we can chroot(get into root) into your install and update grub and remove plymouth and reinstall a new package from repositories. That is the only way I have ever had any success at updating grub in a particular install and making new config file in live cd.

Alright I need you to explain it to me in a bit more detail how I'd get around to fixing this. I really don't know much about Ubuntu.

Sorry I didn't see the part about the fdisk command earlier:

Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Well if you say it was when you used startup manager and changed resolution to 1600x1200 and then attempted edit a plymouth file. So we fix those 2 things.
To get into root in live cd because it will not boot and update the grub takes some commands in terminal, you have make directories and mount a few things and then
get into root and then we can repair the objects that are broken.
I would put the resolution at 800x600 to start with because that we will say works most
all the time. Can change after you can boot into your system.

#In live cd go to Places and to your linux install and mount your Linux partition as before.
Then hit Alt/F2 and box will open and type in gksudo nautilus and hit enter.
That will open file system in root so you can change and save.
Click on your Linux partition on left side of Window that opens and open file system and navigate
/etc/default/grub
change to 800x600 and hit save in upper left. As below is mine at 1024x768:

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
GRUB_GFXMODE=1024x768

Have to be in root to save file is why we do the "gksudo nautilus" part:
After saving you close everything and open a terminal and make sure your internet connection in upper right is connected and in next post will give you the commands to
chroot into system and update your grub and remove and reinstall plymouth.
Will be maybe 10 commands just copy and paste into terminal one at a time.

Your Linux install is sda3: These commands one at a time:
                    

	
	
sudo mkdir /media/root

	
	
sudo mkdir /media/root/proc

	
	
sudo mkdir /media/root/dev

	
	
sudo mkdir /media/root/etc

	
	
sudo mount /dev/sda3 /media/root
                   

	
	
sudo mount -o bind /proc /media/root/proc

	
	
sudo mount -o bind /dev /media/root/dev

	
	
sudo mount -o bind /dev/pts /media/root/dev/pts

	
	
sudo cp /etc/resolv.conf /media/root/etc/resolv.conf

	
	
sudo chroot /media/root

	
	
apt-get remove plymouth

	
	
apt-get install plymouth

	
	
apt-get -f install

	
	
dpkg --configure -a

	
	
update-grub

	
	
exit

	
	
sudo umount /media/root/dev/pts

	
	
sudo umount /media/root/dev

	
	
sudo umount /media/root/proc

	
	
sudo umount /media/root/etc

	
	
sudo umount /media/root
Boot back into Hard drive Ubuntu:

	
	
sudo update-grub

[lifelike27]

At the command: sudo chroot /media/root

I get the error: chroot: failed to run command `/bin/bash': Exec format error

[lifelike27]

Typing: chroot --help

Gives: Usage: chroot [OPTION] NEWROOT [COMMAND [ARG]...]
or: chroot OPTION
Run COMMAND with root directory set to NEWROOT.

--userspec=USER:GROUP specify user and group (ID or name) to use
--groups=G_LIST specify supplementary groups as g1,g2,..,gN
--help display this help and exit
--version output version information and exit

If no command is given, run ``${SHELL} -i'' (default: /bin/sh).

Don't know if that's any help...

I will explain the code to you later: It is not difficult to understand, you just have to mount certain things then run a few commands then unmount them. (umount is not a typo in code)

[lifelike27]

I don't have a problem understanding it, it's just the error I'm getting from running that command.

Is the partition mounted on your desktop: Can you see the partition on desktop(should be)

sudo mount /dev/sda3 /media/root

was the command to mount.

sudo chroot /media/root

is the chroot command:
