I had problems with grub after my installation + my hard drive was not showing up in the devices list when i chose a device to boot (not from setup but before startup). I have tried several methods to restore my grub like this one:
sudo os-prober sudo mount /dev/sda2 /mnt (my mint installation) sudo chroot /mnt sudo grub-install --root-directory=/mnt /dev/sda
I have ran in to this error:
Path '/boot/grub' is not readable by GRUB on boot. Installation is impossible. Aborting.
Have tried several things on forums but none seem to work, any ideas? thx
