Ho installato Ubuntu e poi Windows 7 (per la moglie).
Naturalmente W7 cancella grub e ho provato a reinstallare grub2.

Riavviando il computer con ubuntu mi da l'errore "error 11 : unrecognized
device string"
con windows mi da "Error 21 : selected disk does not exist".

Facendo il comando "sudo Fdisk -l" ho per risposta:

sudo fdisk -l

Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000eb6d1

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1         255     2048256   82  Linux swap / Solaris
/dev/sda2             256        2805    20482875   83  Linux
/dev/sda3            2806       13004    81923467+  83  Linux
/dev/sda4   *       13005       60801   383929402+   7  HPFS/NTFS

mentre per il file "grub.cfg" trovo questo.

Dove stanno gli errori?
Grazie per l'aiuto.
