I have grub installed but it won't take Elementary OS. I have no idea how to boot it manually because the option is there to do it manually.

I do know eOS is located on sda5. I also get the /cow error too and for some reason boot repair won't work either.


you have to boot from live cd and type in terminal

sudo update-initramfs -u;sudo update-grub;

if the problem still exist you have to reinstall grub from the live cd terminal

sudo mount /dev/sda5 /mnt;
sudo GRUB-install --root-directory=/mnt/ /dev/sda;
sudo update-grub;
