Ciao a tutti.
Opensuse 12.3 64 bit

Dopo aver smanettato un tantino mi ritrovo nuovamente all'avvio con la schermata nera ,
la scritta grub col trattino nero, ..e un cigolio continuo dal pc.

Ho provato a riinstallare grub ma il risultato non cambia...

questa la mia situazione

Non so come venirne a capo.

Per avviare il pc ho usato supergrub

Se lancio sudo less /etc/default/grub_installdevice

ottengo

(hd1,2)
(hd1,2)
activate

Visto che sai come diventare root, prova questo comando:

grub2-install /dev/sda

se non hai pasticciato anche con /boot/grub2/grub.cfg dovrebbe ripristinare grub2.
Che scheda video hai? PC o Laptop?

Questo è quanto mi risponde la shell:

linux-u3aq:~ # grub2-install /dev/sda
/usr/sbin/grub2-bios-setup: warning: your embedding area is unusually small.  core.img won't fit in it..
/usr/sbin/grub2-bios-setup: error: embedding is not possible, but this is required for cross-disk install.

Che tipo di PC hai? da quello che posso capire hai Windows installato sul primo disco e Linux sul secondo. A questo punto il comando dovrebbe essere:

grub2-install /dev/sdb

e poi da BIOS scegliere di avviare dal secondo disco.

Così mi funziona. Applause

All'avvio non mi si presentava nessun tema grafico e ho risolto con yast bootloader, opzioni etc...

cambio di risoluzione perchè non partiva, etc... Almeno da per questo ho evitato la shell

la mia situazione:

Nelle voci di boot però non mi figurano nè il failsafe, nè windows 7

Praticamente non mi viene letto l'altro hd?!?

lancio less /etc/default/grub_installdevice

ed ottengo:

(hd1,2)
activate

Per il falsaife non ho idea

in grub cfg
manca il riferimento per windows 7

Un passo alla volta. Hai controllato che in Yast>Sistema>Boot Loader risulti attivato Grub2 e che in Opzioni Bootloader sia spuntato Rileva altro OS?
Purtroppo il mio sistema ha un solo disco e non posso verificare.

Si, già verificato. Ma come vedi sopra nel file di grub 2 manca il riferimento a windows...

Ho finalmente risolto dopo aver fatto delle ricerche in rete:

Ho aggiunto nel file
grub.cfg
il riferimento windows 7:

### BEGIN /etc/grub.d/30_os-prober ###
menuentry "Windows 7 (loader) (on /dev/sda1)" --class windows --class os {
insmod part_msdos
insmod ntfs
set root='(/dev/sda,msdos1)'
search --no-floppy --fs-uuid --set=root 5C72E53F72E51F10
chainloader +1
}

I riferimenti li ho trovati così:

Con fdisk -l ho identificato la partizione windows,

con blkid da root ho identificato l'UUID della partizione windows: --set=root *******************.

Salvato e riavvio.

Lo stesso risultato avrei potuto ottenerlo aggiungendo i soli riferimenti a windows:

menuentry "Windows 7 (loader) (on /dev/sda1)" --class windows --class os {
insmod part_msdos
insmod ntfs
set root='(/dev/sda,msdos1)'
search --no-floppy --fs-uuid --set=root 5C72E53F72E51F10
chainloader +1
}

editando il file:
/etc/grub.d/40_custom
in questo il riferimento viene aggiunto automaticamente al file grub.cfg

Apparentemente grub2 effettua la ricerca per altri OS solo sul disco in cui si trova. Ricordati di inserire in /etc/grub.d/40_custom le istruzioni per Windows 7. Diversamente al prossimo cambio di kernel grub.cfg verrà aggiornato e scompariranno le istruzioni da te inserite.

Già fatto. Grazie mille per l'aiuto.
