# put static boot stanzas before and/or after automagic kernel list

### begin automagic kernels list
## lines between automagic kernels list markers modified
## debian update-grub script except default options below

## not uncomment them, edit them needs

## ## start default options ##
## default kernel options
## default kernel options automagic boot options
## if want special options specific kernels use kopt_x_y_z
## x.y.z kernel version. minor versions can 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=72cec832-188b-40b6-9c41-18fb8b5dd39e ro

## default grub root device
## e.g. groot=(hd0,0)
# groot=72cec832-188b-40b6-9c41-18fb8b5dd39e

## 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 use default boot option, not 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 use default xen boot option
# xenhopt=

## xen linux kernel options use default xen boot option
# xenkopt=console=tty0

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

## controls how many kernels should put menu.lst
## counts first occurence of 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 ignore non-xen kernels when running in domu , 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 value of default booted system
## can true or false
# updatedefaultentry=false

## should update-grub add savedefault default options
## can true or false
# savedefault=false

## ## end default options ##


# divider, added separate menu items below debian
# ones.
title other operating systems:

# entry automatically added debian installer non-linux os

this might not awesome way it, if boot live cd , run

code:

sudo grub-install /dev/sda

might trick.
