I was using my computer last night and today, when I started it up, a screen appeared saying grub rescue unknown file system.

I tried to find the right partition and follow the steps on unknown filesystem, grub rescue and found out that the right partition to boot my device on is (hd0,msdos6), since when I entered grub rescue> ls (hd0,msdos6)/, loads of stuff like lost+found/ etc/ media/ and more came out.

Then, I typed in setprefix=(hd0,msdos6)/boot/grub, following with setroot=(hd0,msdos6) and the next step should be ins do normal, however, I got a message saying error: unknown file system. And when I typed in the command normal, it says Unknown command: normal.

What should I do? I need my computer for school work as I have an assignment to hand in this morning. (If you are just wondering how I am using the internet, I am using my phone. Please help , urgent.


PS: I am not really an expert when it comes to Ubuntu, so please explain a little bit clearer. Thx :)
