I stopped Dualbooting and I dont want to have to choose the OS anymore and just have it load Ubuntu like normal like before?

Any help is appreciated.

If you stopped dual booting, probably you have stopped using the other OS. Why cant you remove the other OS so that ubuntu can boot normally. –  karthick87 Mar 8 '12 at 8:37

@david6: I don't see how either of those are duplicates of this question. I think this is about hiding the grub menu during the timeout. –  oKtosiTe Sep 20 '12 at 9:36
    
Sorry, the second link was supposed to be: askubuntu.com/questions/66070/… This includes how to: Hide the Grub2 menu, and use the default menu option –  david6 Sep 20 '12 at 9:49

So you can just change grub settings.


type in terminal

  1. sudo gedit /etc/default/grub
    you need to change thsis
  2. in the GRUB_HIDDEN_TIMEOUT_QUIET=false change to GRUB_HIDDEN_TIMEOUT_QUIET=true

  3. save that file

  4. type sudo update-grub

IF

you don't get result just look at this bug.

it is currently changed to True but I still see the grub menu... –  Alex Poulos Mar 9 '12 at 4:56
    
Im on 12.04 and i tried this but it already said "true" and it still shows up. The only other OS's I have are the failsafe and Memtest - that's it. I've already deleted my Windows Partition and updated grub and the menu still shows. –  Alex Poulos Mar 9 '12 at 5:11
    
@AlexPoulos look at this link –  geoh Mar 9 '12 at 14:41
    
Worked for me by changing the timeout to 0 and then make it quiet. Thanks –  king_julien Mar 14 at 7:58

I tried all those tips they didnt work, ended up reducing the timeout time to zero as follows:

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

You need to edit the file at /etc/default/grub to prevent showing the grub menu.

By default, the entries in that files look like this.

GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=false
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
  • Remove the # mark from second line, and
  • Change the line GRUB_HIDDEN_TIMEOUT_QUIET=false to GRUB_HIDDEN_TIMEOUT_QUIET=true.

After changes, the required portion of the file will look like this


GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
  • Then run sudo update-grub command in the terminal, and reboot to see the result.

if you want to remove a boot entry just type in:

sudo update-grub

If that doesn't work, install the startup manager, like so:

sudo apt-get install startupmanager


with startup-manager you can

  1. choose with entry to boot in,
  2. choose the resolution and, how long to wait before booting,
  3. you can also choose 0 for automatic booting the default boot-entry
