I installed Windows 8.1 on an MSI GE60 laptop; then proceeded to partition it using GParted (resized the NTFS partitions) and installed Ubuntu 14.04.1 LTS in the free space I created /dev/sda8.

When I run bootinfoscript after logging into Ubuntu, the output looks as follows (see below, excuse the rather long cut-paste). The problem I am having is that I do not have a grub boot menu that allows me to choose which OS to boot into (I used to be able to do this with 8.04 Hardy Heron and 10.04 without much trouble on an older laptop). It boots into Ubuntu by default. The only way I am able to boot into Windows is by hitting the delete key when the MSI logo appears, entering BIOS, and changing the value of the option for Boot Mode Select option from Legacy to UEFI.

Appreciate if anyone has any ideas or suggestions to help me get the grub boot menu option which gives me both OS choices to boot into, so that I don't have to go into the BIOS everytime I want to work in Windows.

Thanks in advance for your time & ideas.

My settings in /etc/default/grub looks as follows:

# If you change this file, run 'update-grub' afterwards to update

# /boot/grub/grub.cfg.

# For full documentation of the options in this file, see:

#   info -f grub -n 'Simple configuration'
