For some reasons I want to install grub2 to my Ubuntu partition(it's sda5) instead of MBR(grub2 will be chainloaded by another loader).
Unfortunately, I can't do this. When I type
sudo grub-install /dev/sda5
I get this:
Path '/boot/grub' is not readable by GRUB on boot. Installation is impossible. Aborting.
sda5 partition is already mounted. What's wrong?
