I have finally installed Ubuntu on my second drive. When I start my computer GRUB only offers me to boot Ubuntu, not Windows 7. What needs to be done so that I can choose between Ubuntu and Windows in GRUB?

When I press F12 for boot menu at startup and I choose Windows Boot Manager it boots into Windows 7.


I ran command sudo fdisk -l and here is log: http://pastebin.com/Cgv1igHc

  1. Boot Ubuntu and mount your Windows partition (simply open the disk on Nautilus)

  2. Run the following on the command line (Ctrl+Alt+t):

    sudo os-prober
    
  3. If your Windows installation was found, you can run:

    sudo update-grub
    

Note that step 2 is just for your convenience. You could just mount the Windows 7 partition and then run update-grub.
