sda1 est en fait une partition ntfs qui couvre la totalité de l’espace disque.
Il est impossible d’installer ubuntu dans une partition ntfs.
gparted ne comprend pas non plus la situation.
Ça risque donc d’être compliqué pour testdisk, mais ce n’est que spéculation.
Seul B1-66ER pourra en dire plus.
La photo d’écran montre au contraire que Gparted comprend très bien la situation. Il affiche bien en beige l’espace occupé dans le système de fichiers NTFS, en blanc l’espace libre dans le système de fichiers NTFS et en gris l’espace à la fin de la partition qui n’appartient pas au système de fichiers NTFS parce que la partition est plus grande qu’elle devrait.
sda1 n’est pas ntfs dans sa globalité.
Les parties grise et blanche à droite sont du ext4.
A quoi correspondent les 2 point d’exclamation entre /dev/sda1 et le carré vert sur la photo ?
Ils expliquent que gparted ne comprend pas comment un bloc “supposé” ext4 pourrait se retrouver écrit à l’intérieur d’une partition sda1 ntfs qui occupe la totalité du disque, de taille 465Go.
Si tu avais initialement une partition sda1 windows, sda2 Ubuntu Mate, puis sda3 Ubuntu “Buggie”, si je compte bien, ça devrait faire 3 partitions.
C’est ça que testdisk doit démêler, mais je crains que…
Pure fantaisie. Gparted ne suppose rien du tout et se moque bien de ce qui se trouve à la fin de la partition. Ce n’est pas son problème. Son seul problème éventuellement, c’est que la partition est plus grande que la taille déclarée dans les méta-données NTFS.
A part la contradiction perpétuelle, tu aimes quoi ?
Qui a dit que gparted “suppose” une partition ext 4 ?
Je, tu, ils supposent que lorsqu’on installe ubuntu par défaut, la partition ubuntu sera “supposée” ext4 (bordel quoi…).
Gparted te dit juste qu’il ne comprend pas cette partition unique sda1 sur le disque.
Typiquement encore un sujet qui va devenir un sujet sur un mois de débat stérile.
Et tout ça pour ubuntu “buggie”.
Salut
Ca ressemble fortement à un souci que j’ai déjà eu (justement, suite à une installation d’ubuntu-budgie).
Vérifie l’ordre d’amorçage des disques dans le BIOS: J’irais bien parier que ton installation n’est pas faite sur ce disque ne comprenant qu’une partition NTFS mais sur un second disque et ton BIOS pousse l’amorçage sur ce disque au lieu de celui sur lequel ton système est installé (sans doute vu comme sdb par ton système).
Si ton BIOS voit bien les 2 disques, tu n’auras qu’à modifier la priorité des disques (ta partition NTFS ayant un flag de boot, si elle est en 1er sur la priorité de disques, elle va monopoliser l’amorçage et faire que ça coince).
Sinon, il suffit de débrancher puis rebrancher le cable SATA de ton disque système (EDIT: machine éteinte, évidemment … ) pour qu’il soit vu de nouveau par ton BIOS et ça repart.
Salut choops,
Bienvenue dans la discussion.
Bon, j’ai fais une analyse du disque avec testdisk, un rapport s’était enregistré dans les documents mais en voulant le poster sur le forum, la session live a planté… chuis bon pour remettre ça demain soir…
Grosso modo il avait trouvé des trucs (Linux/swap) mais il disait qu’il ne pouvait rien faire je crois.
Je poste le rapport demain.
@choops Si rien n’y fait, je regarderais cette piste du BIOS.
Merci !
Comme je maîtrise pas grand chose et encore moins les paramètres du BIOS :
Ton BIOS ne voit qu’un disque dur qui est connecté au port SATA1.
A son petit nom, je dirais que c’est un disque à plateaux SEAGATE de 500G correspondant à ce qui était vu par gparted.
Si tu as un autre disque dur où était installé ton ubuntu-mate et où est maintenant installé ton ubuntu-budgie (ce qui est vachement vraisemblable à l’historique de ce fil), il te suffit d’éteindre ta machine, de l’ouvrir et de débrancher puis rebrancher le cable SATA de ce disque avant de redémarrer.
(Comme je le disais, ça ressemble très fortement à ce que j’avais vécu avec ubuntu-budgie)
@choops Non, c’est un même et seul disque. MATE était installé sur la partie blanche et j’ai voulu installer Budgie sur la partie grise. Avec le temps je pense que cette partition n’était pas “prête” pour une install (formatage en EXT).
Voici le rapport de testdisk :

Hint for advanced users. dmsetup may be used if you prefer to avoid to rewrite the partition table for the moment:
echo "0 810641408 linear /dev/sda 2048" | dmsetup create test0
echo "0 54157312 linear /dev/sda 810643456" | dmsetup create test1

Que faut-il faire ensuite ?
Merci…
Le compte est bon:
Plus qu’à prier très fort avant d’accepter cette proposition de table de partitions.
Si table de partitions OK, il restera ensuite à réécrire le boot-loader dans le MBR.
Bon, il me dit qu’il trouve rien… va falloir que je me fasse à l’idée de tout avoir perdu… ou pas !
J’étais allé dans une asso Linux près de chez moi, je vais probablement y retourner pour voir si il y a pas un spécialiste qui traîne parmi eux.
Je vais m’acheter un SSD pour faire tourner le PC et laisser le disque dur tranquille en attendant.
Comment ça, il ne trouve rien ?
La première proposition de testdisk, citée par @Verner, me semble sensée.
En revanche je ne comprends pas les délires ultérieurs de testdisk.
Je ne comprends pas non plus qu’il utilise encore les coordonnées CHS (obsolètes et illisibles) au lieu des coordonnées LBA. Heureusement il affiche les coordonnées LBA de début dans la proposition suivante :
echo "0 810641408 linear /dev/sda 2048" | dmsetup create test0
echo "0 54157312 linear /dev/sda 810643456" | dmsetup create test1
echo "0 111972352 linear /dev/sda 864800768" | dmsetup create test2
Pour chaque partition le premier nombre est la taille en secteurs et le second la position du secteur de début. Ces informations permettent de recréer les partitions à la main avec fdisk, ou, mieux, sfdisk.
Si tu peux fournir la sortie de
sfdisk -d /dev/sda
je peux te refaire une table de partition avec les trois partitions.
Bon, je n’étais pas allé assez loin. On progresse.
Au redémarrage NTLDR manque a disparu au profit du curseur clignotant en haut à gauche sur écran noir.
Redémarrage sur une session Live.
