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?
