bonjour,
je vais essayer d'etre clair:

j'ai 3 disques dur sur mon pc et j'aimerai en demonter physiquement un pour l'installer sur un autre pc.

j'ai donc fait umount, jusque la tout va bien, mais lorsque que je deconnecte mon disque dur (vide, sans aucune partition), erreur 21!!

voici mon menu.lst

bonsoir,

je dois faire une erreur qq part, a moins que hd2 devienne hd1 mais j'ai pas ose essaye peur de planter tout.

Pour moi le probleme vient de la !!

Dans ton menu.lst je lis :
Sur hd2 tu as ta Ubuntu sur laquelle tu boot, sur hd0 tu as ton XP donc sur hd1 tu as tes sauvegardes.

Si tu enleves hd1 alors hd2 devient hd1 et donc tu dois booter sur hd1
