Error: unknown filesystem. grub rescue

[dank13]

Salve a tutti.
Hpnun portatile dual boot, ubuntu 15 + win. Un paio di giorni fa ho deciso di aggiornare Ubuntu 15 alla versione 1 un paio di giorni fa ho deciso di aggiornare Ubuntu 15 alla versione 16 tramite chiavetta US un paio di giorni fa ho deciso di aggiornare Ubuntu 15 alla versione 16 tramite chiavetta USB. Dopo aver modificato dal bios l'ordine di boot l'installazione purtroppo non è andata a buon fine. Il problema è che ora all'avvio del computer non mi carica né l'uno né l'altro sistema operativo (pur avendo riordinato l'ordine di boot)
All'avvio compare la famosa scritta:
error: unknown filesystem.
grub rescue>

che fare?
grazie!

Boot successfully repaired.

You can now reboot your computer.

Lo incollo prima di riavviare...non si sa mai

[dank13]

Niente da fare.
Purtroppo anche dopo il riavvio il problema permane (anche dopo aver riordinato l'ordine di boot da BIOS)
L'unica cosa che mi ha dato da pensare è che ogni volta che mi collego tramite LIVE mi compare questo messaggio d'errore

[wilecoyote]

Salve, 1° cosa questa:

=================== UEFI/Legacy mode:
This live-session is not in EFI-mode.
SecureBoot maybe enabled.

Dalla domanda sembra che non hai disabilitato il Secure boot.

2° cosa quest'altra:

1 disks with OS, 2 OS : 1 Linux, 0 MacOS, 1 Windows, 0 unknown type OS.

Windows not detected by os-prober on sda2.

Boota da /dev/sda1 ma sembra che non trova Window nella partizione /dev/sda2, hai forse toccato involontariamente le partizioni di Window ?

Strano che non funzioni BootRepair, finora mi ha sempre tolto dall'impicci.

Proviamo in un altro modo, leggi questa wiki AmministrazioneSistema/SuperGrubDisk, scarica il SuperGrubDisk e segui le istruzioni d'uso, arrivato al punto 3 seleziona la partizione /dev/sda8 di Ubuntu così di far bootare da esso.

Prima però leggi, o meglio scarica e stampa, la guida per Grub 2 linkata al punto 5 che dovrai seguire una volta avviato.

Ciao

Alla fineo preferito installare win10. Adesso installero ubuntu 16.10 dual boot
