asked on fedora boot order
I installed fedora ( I think it's version 19 ) on two partitions of my laptop. I will use one to get emails and stuff, and the other for banking.
the problem is the install of fedora i want to be the default if not the default. /etc/default/grub looks like this.
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="cons
GRUB_CMDLINE_LINUX="rd.lvm
GRUB_DISABLE_RECOVERY="tru
I have been googleing but can't find how to change the boot order. Or I should say, I have found a lot of "fixes" that aren't working.
anyone have a good step by step that changes the boot order for fedora 19?

Ok, so at a terminal I did this
su
vi /etc/default/grub
changed
GRUB_DEFAULT=saved
to
GRUB_DEFAULT=2
( I actually want to 3rd line to be the default )
then ran
grub2-mkconfig > /boot/grub2/grub.cfg
but it's like it ignored the changes and the default is still the 1st line of
/etc/default/grub

is it in 3rd line when you run grub2-mkconfig ?

sorry, I'm not sure what you mean. when i edit
/etc/default/grub
once I'm done I save the changes and exit. Then I run
grub2-mkconfig> /boot/grub2/grub.conf

the destination file is grub.cfg not grub.conf (you know they save one byte)
while grub2-mkconfig > /boot/grub2/grub.cfg is running it displays couple of lines with all kernels you have installed. so number them from 0 and choose the right one you want to boot for the next try.
(to remove old kernels use yum upgrade as opposed to yum update)

I don't know if I'm counting the lines wrong in grub.cfg, but no matter what number I put in
GRUB_DEFAULT=
after I run
grub2_mkconfig>/boot/grub2
and reboot, the default doesn't change. This is what grub2_mkconfig looks like when it runs
# grub2-mkconfig>/boot/grub2

any idea what number goes in
GRUB_DEFAULT?
or would it be
GRUB_DEFAULT= /dev/mapper/fedora00-root

oh, I'll try that. Up to this point I would put
GRUB_DEFAULT=2
without all the other stuff.
GRUB_DEFAULT=2

I can confirm that it works on Ubuntu like you typed.

"Set GRUB_DEFAULT=2 in /etc/default/grub"
I thought you meant literally to put
2 in /etc/default/grub
but I realized to put
GRUB_DEFAULT=2
in the file called grub at /etc/default
the thing is I already tried that and it didn't work. In fact I've tried several things at
GRUB_DEFAULT=
and it seems like it just ignores whatever I put there, even though I run
grub2-mkcoonfig > /boot/grub2/grub.cfg
after each change, then I reboot

Weird. It mus have some other place it reads real settings...
ASKER
thank you
So you have to run
grub2-mkconfig > /boot/grub2/grub.cfg
