Bon apparement je m’explique très mal
je vais essayé d’éclairer tout ca
Au démarrage j’avais toute une partition de 10go (hda3) réservé a debian c’etait pour la testé. Lors de l’install je n’avais fait que deux partitions une pour l’install complete et la swap.
[quote=“Ricardo”]A l’allumage, c’est bien le hda3 qui s’ouvre ? [/quote]Oui c’est bien sur hda3 qu’il va voir la config mais je veux qu’il aille le voir sur hdb1 car j’ai transferé mes données la-bas. Ce que je pense faisable c’est de faire fonctionner grub en laissant le boot sur hda3 et de le déplacer une fois fonctionnel.
ce qui donnais donc pour le disque hda
partition windows partition debian et swap
J’ai fait l’acquisition d’un disque dur de 80go sur lequel j’ai transferé tout ce qu’il y avait sur la partition de 10go réservé a debian pour lui laisser un peu plus de place et ceci en partitionnant le disque hdb
ce qui me donne donc maintenant la meme chose pour le hda mais maintenant pour hdb j’ai
partition racine hdb1
partition home hdb5
partition var hdb6
partition usr hdb2
partition tmp hdb7
j’ai tout transferé sur hdb en respectant les partitions mais maintenant il reste a configurer grub pour qu’il prenne en compte tout ca. C’est a dire oublié completement hda3 et le remplacer par hdb1.
J’ai essayé un grub-install mais ou meme differents autres moyens et je doit me tromper au niveau des partitions car il me dit qu’il ne les reconnais pas 
Voici le menu.lst initiale sur la partition hda3 que j’ai reussi a copier sur cle usb avec windows 
[code]# 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’.
default 0
timeout sec
Set a timeout, in SEC seconds, before automatically booting the default entry
(normally the first entry defined).
timeout 5
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/

[/code]lorsque je vire completment tout ce qu’il y a sur hda3 afin de ne laisser que ce que je veux avoir c’est a dire la config complete sur hdb il ne me trouve pas la partition de démarrage et ne lance pas grub.
Si je laisse le repertoire /boot sur hda3 et que je le configure je peux booter sous windows mais si j’essaye linux j’obtiens soit un kernel panic soit il ne reconnait pas la partition.
Pour plus d’info sur ce que j’ai fait et ce que je veux faire voir mon autre post forum.debian-fr.org/viewtopic.php?t=2465
