Grub menu won't show up after updating Ubuntu, can boot only into Windows

Eyob

I recently installed Ubuntu 13.10 on my Toshiba P55 A5200 and everything was working perfectly. After I updated Ubuntu and installed a few applications GRUB menu won't show up and my computer only boots directly into Windows.

Your help is appreciated.

You can try reinstalling grub from within the live cd. Remember to replace 'sdX' with your desired boot disk/partition.

$ sudo grub-install /dev/sdX

$ sudo update-grub

If that fails try using boot-repair by following the steps below:

  1. Boot into your live cd.
  2. Download and install boot-repair (instructions here).
  3. Run from terminal: $ sudo boot-repair
  4. Select 'fix recommended'
  5. Reboot.
