Grub - Boot Sequence.

August 10th, 2012 - 02:28 am ET by Kanjana | Report spam

Hi Guys/Gals,

I just removed Linux Mint 13 (Maya) from my machine and successfully
replaced it with LMDE 201204 with Mate and Mint menu.

I then installed Ubuntu 12.04 LTS and have now a workable dual-boot
set-up, however the grub menu displays Ubuntu before LMDE.

I wanted to change the boot sequence so that LMDE starts-up first
(automatically after about 10 seconds or so).

So, I went into the Ubuntu Teminal:

sudo gedit /etc/etc/default/grub

to edit the file accordingly but this proved to be a little too
confusing & complex for my limited knowledge (I can not identify the
right items to move). I then looked at "info -f grub" but this is all
too technical for me also. Before botching up the grub menu could
somebody please have a look at the document and change it so that LMDE
starts up before Ubuntu, thanks.

You can't change the the ordering of the items in the boot menu
as far as I know (unless you change the scripts generating the
menu). But you can specify which menu item must be selected by
default.

So, I went into the Ubuntu Teminal:

sudo gedit /etc/etc/default/grub

to edit the file accordingly but this proved to be a little too
confusing & complex for my limited knowledge (I can not identify the
right items to move). I then looked at "info -f grub" but this is all

# If you change this file, run 'update-grub' afterwards to update

# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'

So start: info -f grub -n 'Simple configuration'
and look for GRUB_DEFAULT

GRUB_DEFAULT=0

This says that the first menu item must be selected by default. Items
are counted from 0. "0" is the first item, "1" the second, and so on.
Instead of specifying a number you can also give the full name of the
menu item you want to select.

Would I have a home-run if I were to change the script like this?

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

Please confirm or correct, thanks.

You could do it like this:
Booting LMDE,...
# sudo grub-install /dev/sdX, (where X most likely are a, (sda)),
now You boot default to LMDE,...

Then, if, LMDE are based on Debian install StartUp-Manager,...
(anybody know why this disappear from Ubuntu,...?)

Then i change 3 lines in /etc/default/grub to this:

GRUB_DISTRIBUTOR=`lsb_release -d -s 2> /dev/null || echo Debian`
GRUB_DISABLE_LINUX_UUID=true # i hate UUID
GRUB_DISABLE_RECOVERY="true" # if more than one dist don't need

and # sudo update-grub
(must be done for all dist installed)

For home-runs you need to play aonther kind of game. ;-)

Are you the original poster BTW?. Conversation will be easier if
participants use the same name during the whole thread.

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

I don't see any difference, apart from the line ordering,
between this and the similar part from the original message.
Changing the order of the statements in /etc/default/grub
won't influence the boot menu.

Adjust the value of GRUB_DEFAULT to select a different boot
menu item as default.
GRUB_DEFAULT=0 selects the first item of the boot menu,
GRUB_DEFAULT=1 selects the second item,
GRUB_DEFAULT=2 selects the third item, etc.

Run 'update-grub' afterwards as mentioned in the start of the document.

Regards,

Kees.
