Secure boot locking is the culprit. Some laptops don't give the option to disable it. You can change from UEFI boot to Legacy but within UEFI, secure boot is locked. From the net it appears that Ubuntu 15.04+ has the required software to install in UEFI with secure boot enabled and there is no need to run boot-repair. Have yet to try it.

I think you should be getting option to disable secure boot in bios. That's the main thing required. Next is disable fast boot and enable legacy boot.
Are you able to start live disk of Ubuntu? If yes means your legacy boot is working.

Deep,
Thanks for responding, but the steps you are describing is for a proper
EFI
boot systems.
In any case the link describes the steps for such a system, and the
restart
options screenshot is nothing like mine. I do not get the EFI options as shown, so I can't proceed.
To repeat my problem, my HDD is legacy booting (MBR partitioned), so
Ubuntu
complains it needs EFI and won't accept the free space I had created in
C:
I hope someone can suggest a workaround.
I have done this before with windows 7, and Ubuntu 12.04, but I never encountered this issue.

Hello Royce,
Have you tried following a detailed guide such as this one: http://technozed.com/install-ubuntu-linux-alongside-windows-10/
Honestly, there are quite a few guides on internet that show precise
steps
heavily detailed on how to proceed with installation. And a lot of cumbersome process has actually been sorted if you are installing
Ubuntu
15.04 / 15.10 such as having the need to run boot-repair when it fails
to
show the bootloader at the time of startup that lets you select which
OS
to
boot into.
Usually, you are required to turn off Fast Boot from Power Settings (so that Windows doesn't force into booting only itself and instead shows
you
options to boot into other OSes) disable Secure boot from your BIOS Settings and then do the actual installation.
And even when doing the installation, you must actually boot from the
USB /
CD ROM that contains Ubuntu Installation files on it and boot into
Ubuntu
into Try mode and see for yourself that all necessary peripherals such
as
network devices, sound card, display, etc are working fine for your machine's make/model and if you are satisfied, only then go ahead with
the
installation from there itself.
As you have already partitioned the drive from Windows (which is a good thing to do), you will now be able to use a GParted UI to create
partitions
for your new linux installation ensuring Windows Partitions are not
messed
up with at all during this process.
After the installation is done, there are chances that you will have to
run
boot-repair (again covered in the link I mentioned above). Although
this
boot repair thing is not required (usually) if you are installing 15.10 (Willy Werewolf). ᐧ

The HDD had windows 7 before, with 2 partitions C: and D:.
Yes, there is a a recovery partition of 450mb after C:
In my BIOS setting, CSM settings show boot options as: UEFI or
legacy.
Thank you.

In your BIOS check the EFI Legacy option for the HDD too. How come
your
Win
10 is installed in legacy mode? Did you upgrade from an old Win 7?
Did
you
have partitions after C: ? Generally nowadays they come with the
recovery
partition after C: in order to make it difficult to install another
OS.

Hi,
I have a Windows 10 PC with was installed in 'legacy' mode (not
EFI).
I shrunk my C: to create free space of 25Gb for Ubuntu.
I created a 64 bit Ubuntu bootable USB pendrive.
For booting from the pendrive, I select the boot mode at the BIOS
splash
screen I have tried both 'USB drive' and 'EFI-USB-drive'.
I tried to install Ubuntu 15.1 but the free space is always
marked
'unusable'.
Before this I'd got a warning that the installation was started
in
EFI
mode, but target installation is non-EFI, and if I force it I
won't
be
able
to switch OSs. But this warning is not appearing subsequently, only my freed
partiton
is
showing 'unusable'.
Is there a way install Ubuntu into the created free space in
such a
situation?
