This question already has an answer here:
- Grub rescue - error: unknown filesystem 5 answers
i'm a fresh ubuntu user and I've installed a double boot with Wind 8 and Ubuntu 13.04, but since yesterday I'm receiving an error showing:
error: unknown filesystem grub rescue>
The fact is when I do ls (hdX,gptY)/ all I get is "error:unknown filesystem" again.
And the solutions posted don't work because I don't know why but I can't access the BIOS pressin F2 or to the boot pressing F12, the simply don't work since the error.
