[Débutant] Gave up waiting for root device

Bonjour
J'ai installé Ubuntu avec une clé usb en dual boot avec windows 10.
Mais au premier démarrage d'Ubuntu, j'ai eu le message d'erreur suivant:

Gave up wainting for root device. Common problems :
    - Boot args (cat /proc/cmdline)
         - Check roodelay= (did the system wait long enough?)
         - Check root= (did the system wait for the right device?)
    - Missing modules (cat /proc/modules; ls /dev)
ALERT!  /dev/sdc4 does not exist. Dropping to a shell!

Je suis débutant, je n'ai jamais utilisé Ubuntu.
Merci de votre aide.

Bonjour,
Peux-tu faire un Boot-Info et donner l'URL de ce Boot-Info dans ta réponse ?

Voilà, j'ai réussi à faire un boot-info comme vous me l'avez demandé.
Voici l'URL : http://paste.ubuntu.com/12186606/

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sda1 into the MBR of sda.
Additional repair would be performed: unhide-bootmenu-10s


=================== Blockers in case of suggested repair
Veuillez utiliser ce logiciel dans une session-live (live-CD ou live-USB). Cela vous permettra d'utiliser cette fonctionnalité.


=================== User settings
The settings chosen by the user will not act on the boot.

On peut voir la référence du disque dur dans cet extrait du Boot-Info :

=================== parted -l:

Model: ATA WDC WD600BEVS-75 (scsi)

Il s'agit d'un WESTERN DIGITAL Scorpio Blue 60 Go
Ce disque dur ne contient qu'une installation de Ubuntu 15.04 32 bits. Je ne vois pas la présence de Windows 10 qui devrait être installé en dual-boot d'après ce que tu as écrit dans le post #1. Peux-tu expliquer cette absence de Windows 10 ?

D'autre part, peux-tu donner le nom du modèle de ton ordi et son fabricant ?
