I think we are back to the problem I said you would get if the installer 
installed from the normal boot menu and not from the grub screen which 
only appears when you boot the disk in EFI mode.  Look at the EFI boot 
partition - it is a small partition at the beginning of the drive.  It 
is only about 240 MB in size.  In it, there will be Windows boot 
instructions in one directory, and if it has installed correctly, there 
ought to be an Ubuntu directory in the same partition with Ubuntu 
instructions.  If it is not there, the installer has installed in BIOS 
mode - and strictly, the two systems shouldn't be mixed.

If the Ubuntu directory is there, then there is a bug in the installer, 
you should report it.  In your case, it ought to be fixable by 
re-installing grub and doing an update.  That should (hopefully) not 
stop the ability to boot Windows, but only from the new grub screen.  No 
guarantees!  If you do report it as a bug, let me know - I can probably 
confirm it after a couple of tests.

If it has been installed in BIOS mode, you may get away with it if you 
do an 'install-grub' followed by an 'update-grub', but this process WILL 
destroy the ability to boot directly into Windows as you can now do. 
Hopefully, update-grub will find both systems and allow proper booting 
of both OSs from the new grub screen that will appear.  I can't 
guarantee it though, hence the BIG note of caution.  Be prepared to 
re-install Windows.

In the latter case, the safer option would be to re-install Ubuntu from 
a disk booting in EFI mode and to use the disk boot grub screen.
