Bonjour,
J’ai installé Debian 4.0 r3 sur mon PC en dualboot XP-Ubuntu
Voici ma table de partition:
[code] Start End Blocks Id System
/dev/hda1 * 1 3916 31455238+ 7 HPFS/NTFS Windows XP
/dev/hda2 3917 4569 5245222+ 83 Linux Ubuntu
/dev/hda3 4570 5222 5245222+ 83 Linux Debian
/dev/hda4 5223 9733 36234607+ 5 Extended

/dev/hda7 9603 9733 1052226 82 Linux swap / Solaris[/code]
Debian est bien installé sur /dev/hda3, (vérifié avec SuperGrubDisk) mais Ubuntu ne démarre plus 
y compris avec SuperGrubDisk.
Voici mon menu.lst Ubuntu:

J’avais l’intention de booter Debian par une entrée en chainloader dans mon GRUB Ubuntu qui se lance au démarrage.
Il me semble que ma partition Ubuntu n’est plus reconnue comme /.
Est-il possible de corriger cela?
Ou bien s’agit-il d’autre chose?
Ou bien faut-il réinstaller Debian? Mais je ne vois pas ce que j’ai loupé lors de l’installation. 
Merci par avance.
