ok d'accord merci pour tout

PS:ca signifie koi distros?et MP? lool

ok d'accord merci
si j'y arrive pas jte dirais

dire ke le problème venait juste d'un 6 a la place d'un 5...
apparament le plus dire reste a faire ............................................
euh......je suis vraiment obligé de reediter le menu.lst ???
et par hasard est-ce ke tu saurais pas si les pc fujitsu sont tatoués ou pas(si ca m'empecherait de mettre xp a la place de vista ou de formater la partition vista )???????

ok d'accord c pour ca ke ca fonctionnait pas.... j'y retourne merci

merci apparament ca a l'air de fonctionnée je reboot tout de suite et je te dis initials 76

c'est bien ce que je pensait :)
tes partitions ont changé de nom....

donc:

sudo grub --batch

ensuite

root (hd0,5)

ensuite

setup (hd0)

ensuite

quit

reboot

ton grub pointait en fait vers ta swap,a cause de la modification des nom de partitions ;)

voilà

c bizarre parce ke je l'ai deja fait plusieur fois sans souci (sans ke ca me dise Error 21: Selected disk does not exist) mais ca n'as jamais reglé le problème de grub et là ca me fait

grub> root (hd0,6)
root (hd0,6)

Error 21: Selected disk does not exist

ok j'essaye tout de suite

et bien alors tu complète les commandes :)

toujours a l'invité grub>

root (hd0,6)

ensuite

setup (hd0)

ensuite

quit

ensuite

reboot

au démarrage suivant ton grub devrait etre réparré

En revanche en allant directement au menu.lst de grub ca me donne ca :

# menu.lst - See: grub(8), info grub, update-grub(8)
# grub-install(8), grub-floppy(8),
# grub-md5-crypt, /usr/share/doc/grub
# and /usr/share/doc/grub-doc/.

## 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 change this entry to 'saved' or your
# array will desync and will not let you boot your system.
default 0

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout 10

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

# Pretty colours
#color cyan/blue white/blue

## password ['--md5'] passwd
# If used in the first section of a menu file, disable all interactive editing
# control (menu entry editor and command-line) and entries protected by the
# command 'lock'
# e.g. password topsecret
# password --md5 $1$gLhU0/$aW78kHK1QfV3P2b2znUoe/

### BEGIN AUTOMAGIC KERNELS LIST
## lines between the AUTOMAGIC KERNELS LIST markers will be modified
## by the debian update-grub script except for the default options below

## 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=67831565-985d-4954-bfdd-e53245684819 ro

## Setup crashdump menu entries
## e.g. crashdump=1
# crashdump=0

## default grub root device
## e.g. groot=(hd0,0)
# groot=(hd0,6)

## 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 locale=fr_FR

## 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

## 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
# savedefault=false

## ## End Default Options ##

ok
tapes ceci:

sudo grub --batch

ensuite:(a l'invité grub>)

find /boot/grub/stage1

et copies colle moi ce que répond la deuxième commande sans fermer le terminal

merci d'avoir repondu

voilà
ubuntu@ubuntu:~$ sudo -s
root@ubuntu:~# sudo cat /media/disk/boot/grub/menu.lst
cat: /media/disk/boot/grub/menu.lst: Aucun fichier ou dossier de ce type

salut :)

il va falloir je pense,modifier ton menu.lst depuis le live cd...

depuis le cd live essayes toujours de taper ceci dans le terminal et copies/colles moi le résultat:

sudo cat /media/disk/boot/grub/menu.lst

/media/disk/ devrait correspondre a ta partition ubuntu

si il y a un message d'erreur copies le aussi
