View Full Version : [ubuntu] Does the Grub list for default boot value include the seperator?

Basically, I commented (#) all the boots I didn't want included in Grub, to leave only three:

Ubuntu, Ubuntu recovery mode and Vista

However when I set the default value to 2, the highlighted value isn't Vista, it's the seperator between the two (Linux vs Windows)

What I'm wondering is, should I set the default to 3, or should I leave it this way and Vista would boot automatically anyway..?

Thanks!

Post your menu.lst for review.

tail -n 30 /boot/grub/menu.lst

I'd like the default to be Vista.

I'm not on Ubuntu right now... will post it when I boot back on it :)

## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not use 'savedefault' or your
# array will desync and will not let you boot your system.
default 2

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout 7

# Hides the menu by default (press ESC to see the menu)

### BEGIN AUTOMAGIC KERNELS LIST
## lines between the AUTOMAGIC KERNELS LIST markers will be modified

## DO NOT UNCOMMENT THEM, Just edit them to your needs

## ## Start Default Options ##
## default kernel options
## default kernel options for automagic boot options
## If you want special options for specific kernels use kopt_x_y_z
## where x.y.z is kernel version. Minor versions can be omitted.
## e.g. kopt=root=/dev/hda1 ro
## kopt_2_6_8=root=/dev/hdc1 ro
## kopt_2_6_8_2_686=root=/dev/hdc2 ro
# kopt=root=UUID=d25e3a19-8bfb-4a53-84f0-74eecf7b01d9 ro

## default grub root device
## e.g. groot=(hd0,0)
# groot=d25e3a19-8bfb-4a53-84f0-74eecf7b01d9

## should update-grub create alternative automagic boot options
## e.g. alternative=true
## alternative=false
# alternative=true

## should update-grub lock alternative automagic boot options
## e.g. lockalternative=true
## lockalternative=false
# lockalternative=false

## additional options to use with the default boot option, but not with the
## alternatives
## e.g. defoptions=vga=791 resume=/dev/hda5
# defoptions=quiet splash

## should update-grub lock old automagic boot options
## e.g. lockold=false
## lockold=true
# lockold=false

## Xen hypervisor options to use with the default Xen boot option
# xenhopt=

## Xen Linux kernel options to use with the default Xen boot option
# xenkopt=console=tty0

## altoption boot targets option
## multiple altoptions lines are allowed
## e.g. altoptions=(extra menu suffix) extra boot options
## altoptions=(recovery) single
# altoptions=(recovery mode) single

## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
## alternative kernel options
## e.g. howmany=all
## howmany=7
# howmany=all

## specify if running in Xen domU or have grub detect automatically
## update-grub will ignore non-xen kernels when running in domU and vice versa
## e.g. indomU=detect
## indomU=true
## indomU=false
# indomU=detect

## should update-grub create memtest86 boot option
## e.g. memtest86=true
## memtest86=false
# memtest86=true

## should update-grub adjust the value of the default booted system
## can be true or false
# updatedefaultentry=false

## should update-grub add savedefault to the default options
## can be true or false

Number 3 should boot Windows, just go ahead and change it.

It won't mess anything up if the value is wrong? I mean if three doesn't work and none are selected by default, will it still all work ok?

To answer your oiginal question, YES, GRUB counts the separator.

And no, it doesn't hurt anything the experiment with the default number. All that will happen is that it will not boot into what you want.

Just reboot into something that works, change the default number, and reboot again.
