I just installed elementary OS Freya in a partition where the old elementary OS Luna used to be, but in grub I can't see the option to boot with Freya, but the old Luna one. When selecting this one the computer restarts again.
The grub partition already existed because I have Ubuntu. I chose /dev/sda8
as the partition were elementary OS would be installed, but I wasn't really sure about this one. It's the same partition I chose for elementary to be installed.
So why is it missing in grub?
update-grub
?
