[Grub] errore 18 GRUB

[njin]

ops scusa non avevo visto il tuo ultimo post, salva e riavvia.

[mikelosat]

si sto da live cd, non mi fa salvare, ora provo il tuo comando

[njin]

Questo dovrebbe essere il percorso giusto

Quindi devi aprire un terminale e digitare

cd /media/disk/boot/grub #per spostarti nella directory dove risiede menu.lst
sudo gedit menu.lst #per aprire menu.lst con un editor di testo (gedit) in modalità amministratore (sudo)

e cambi tutte le scritte

root      (hd0,6)

in

root  (hd0,2)

[mikelosat]

raga niente da fare, vi faccio vedereper sicurezza come ho editato il file menu.lst:

sda2 e sda5 contengono dati??
montami la sda6 e dimmi cosa contiene

[mikelosat]

sono un novello di linux mi spiegheresti come devo fare per montartele ?

[njin]

Da live cd come ti ho detto ieri.
Places -> computer e doppio click sulla partizione più piccola che hai (quella di boot che hai creato per intenderci) ti dovrebbe dare un errore, non farci caso, chiudi tutto e la trovi montata sulla  scrivania, click dx e scegli browse

[mikelosat]

ok fatto!!

si ci stanno due cartelle  grub e lost+found più altri files

[njin]

c'e' ne una con scritto grub?

[mikelosat]

si ci sta!!

[njin]

postami il menu.lst contenuto in quel grub....

Bene il file e' ok.
Ora proviamo a riscrivere grub su mbr, e' semplice, segui la guida al primo punto oppure usa supergrub disk.

http://wiki.ubuntu-it.org/AmministrazioneSistema/Grub/Ripristino?highlight=(grub)

ovviamente smonta sda6 click dx - unmount

[njin]

La tua partizione di boot e' sda6 e corrisponde a  hd0,5
quindi root (hd0,5)
salta il punto 3
al punto 5 digita setup (hd0) per scrivere su mbr

[mikelosat]

allora sto seguendo il primo metodo della tua guida, arrivo a digitare :  find /boot/grub/stage1

Codice: Seleziona tutto

grub> find /boot/grub/stagel

Error 15: File not found

grub> find /boot/grub/stage1

Error 15: File not found

grub>

Si scusa guarda il post precedente e saltalo.
