I just installed Ubuntu on my computer. It installed fine, but on the reboot it says:
error: file /grub/i386-pc/normal.mod
I don't understand. I have tried many things I have found on these sites to try and fix it but it normally comes up with unknown command. For example I type in
sudo grub-install /dev/sda and it says
unknown command: sudo. I really would like to figure this out please help me!
