[RISOLTO][Grub] pasticcio partizioni e grub rescue

[eufass]

buongiorno,
su acer aspire ho win7 e poi maverick
ho aggiunto una partizione fat32 (volevo leggere posta sia con win che linux), al reboot mi ha dato grub rescue (ahhhhg!!!!)
adesso sono con usb live,
ho letto le istruzioni "Ripristinare Grub", ma vorrei essere sicuro di non avere fatto un grande casino
allego immagine gparted
grazie

per aggiungere la partizione hai spostato quella di Ubuntu ? la prossima volta riduci partendo da destra e non da sinistra.

con cat /etc/fstab mi hai postato il fstab della live, avevo detto
il contenuto di /etc/fstab e di /boot/grub/grub.cfg preso dalla partizione sda6

[eufass]

scusa,
ecco:

# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
#
#            
proc            /proc          proc    nodev,noexec,nosuid 0      0
# / was on /dev/sda5 during installation
UUID=0066e72d-b865-431f-86a5-2ab911c60eba /              ext4    errors=remount-ro 0      1
# swap was on /dev/sda6 during installation
UUID=3020ae69-30ac-4d13-b459-66ca696c4961 none            swap    sw              0      0
/dev/sda3      /media/ACER    ntfs-3g silent,umask=0,locale=it_IT.utf8 0 0

[patel]

grub.cfg e fstab sono ok, quindi basta ripristinare il grub seguendo la guida http://wiki.ubuntu-it.org/Amministrazio ... Ripristino utilizzando sda6 al posto di sda1 e non considerando la parte relativa a /boot.
Se hai difficoltà posta tutto quello che appare a terminale.
Altro metodo è utilizzare Supergrub2 http://developer.berlios.de/project/sho ... p_id=10921
lanciare Ubuntu e dare da terminale

sudo grub-install /dev/sda
