changing OS selection at boot selection screen

gcmhmedic17 · 12-21-2010, 11:13 AM

Good afternoon. I am trying to find the best and correct way to change the Windows Vista selection from the bottom of the selection menu at the system boot screen to the top. Also, I am looking to find out if it is possible to remove the rest of the selections other then the Ubuntu 8.10 choice without corrupting the system. Thanks in advance, and have a Merry Christmas and a safe and happy New Years holiday.

Install startupmanager package in Ubuntu.

open a terminal and type

Quote:

sudo apt-get update

Quote:

sudo apt-get install startupmanager

You can change boot order, splash image and a few more things with Startup Manager.

Are you using grub or lilo?
For grub
Edit

Code:

/boot/grub/grub.conf

(or, equivalently, /etc/grub.conf). There's
Look for the line

Code:

default=some number

If the number is 0, the default corresponds to the first in the series of
titles in grub.conf. If it's 1, the default corresponds to the second.
etc..

For lilo
Edit

Code:

/etc/lilo.conf

Look for the line that says

Code:

label=what yo want to boot first,

and change the line that says default= to the above label.
run

Code:

lilo

to make the changes

Kind regards

the file you are looking for is /boot/grub/grub.cfg or /boot/grub/menu.cfg(lst?), must be edited as root
though it would probably be easier to change this line

Code:

set default="0"

to the one you want as opposed to moving them, but simply moving the menuentry section eg:

Code:

menuentry 'Ubuntu, with Linux 2.6.32-27-generic (recovery mode)' --class ubuntu --class gnu-linux --class gnu --class os {
	recordfail
	insmod ext2
	set root='(hd0,1)'
	search --no-floppy --fs-uuid --set d43e0044-5a1d-4f17-abc3-c6fd77b20dd7
	echo	'Loading Linux 2.6.32-27-generic ...'
	linux	/vmlinuz-2.6.32-27-generic root=UUID=44169a1f-a1aa-476a-9837-48ccb9853381 ro single 
	echo	'Loading initial ramdisk ...'
	initrd	/initrd.img-2.6.32-27-generic
}

though the one for windows would be smaller
to the top should also work
just be careful to copy everything including the brackets

you are right for grub 1 it is /boot/grub/menu.lst

to edit it as root try entering :

Quote:

sudo gedit /boot/grub/menu.lst

-for grub 1

Quote:

sudo gedit /boot/grub/grub.cfg

- for grub2

in a terminal
