After updating from 14.04 to 14.04.3 I am unable to boot directly to my OS without being presented with a grub menu (yes I have boot-repair and have used the standard fix)

What is the output of:

sudo update-grub; lsb_release -a; cat /etc/default/grub

Thanks

 sudo update-grub; lsb_release -a; cat /etc/default/grub

Thanks for your time to help.

Edit your /etc/default/grub file and change

#GRUB_HIDDEN_TIMEOUT=0

to

GRUB_HIDDEN_TIMEOUT=2

and after saving your changes run "sudo update-grub"

Just removing the # from the line should get you the behaviour you want - however if you need the grub menu to select an older kernel or specify boot options you'd have problems getting the menu. By selecting GRUB_HIDDEN_TIMEOUT=2 you have 2 seconds in which to hold down the shift key and bring up the grub menu. Go ahead and set it to 1 if you want and even speedier boot to the login screen.
