GRUB no me detecta los otros SO.

[Marvin Velasquez <marvinbcn01@gmail.com>]

Hola Amigos!!

Les comento mi fallo,

tengo un netbook que viene con w27 y androide en otra particion, y
otra particion de recovery,

yo he creado una partición para instalarle Ubuntu,hasta aqui todo bien
porque GRUB me detectaba los SO.

Borre la partición de Ubuntu y nuevamente la cree para instalarle Debian

Debian se instalo sin problemas pero "GRUB" no me reconoce w27 ni  Androide??
que podria ser el fallo que tengo???

Adjunto mas informacion: fdisk -l
