Remove 2.8 and dual boot 3.4 with Ubuntu

[gold_finger]

As suspected, the os-prober script has been de-activated in Ubuntu so it doesn't run when doing an update to grub, therefore doesn't add entry for new LL3.4.  You'll need to re-activate it by running this command from a terminal in Ubuntu:

Code:

sudo chmod 755 /etc/grub.d/30_os-prober

Now run command to update grub:

Code:

sudo update-grub

Reboot and you should see an entry for LL3.4 and be able to boot into it.


In all likelihood you'll still see an old (non-working) entry for LL2.8 as one of the choices.  I suspect that 40_custom script in Ubuntu's /etc/grub.d folder may have been used for that.  Post back output of this command from a terminal in Ubuntu:

Code:

cat /etc/grub.d/40_custom
