I have installed Ubuntu alongside Windows 10 to different local disks. But on the booting window, Windows 10 isn't showing after installing Ubuntu- there is only Ubuntu on the menu.

How do I enter Windows 10?

Note that when I installed Ubuntu it warned me that Windows 10 was installed with BIOS compatibility mode, but Ubuntu would install in UEFI mode. Nevertheless I have forced the install. Is it the reason that Windows 10 isn't shown?

    I don't no much about UEFI and Legacy Mode. I think It's related to BIOS. Even I faced the same issue in Dell Latitude 3450 laptop. After changing Setting in bios I was able to boot. OR boot into Ubuntu open terminal login as root and enter the command update-grub. – max Aug 2 '15 at 15:34

I think you need to install grub.

sudo add-apt-repository ppa:yannubuntu/boot-repair

sudo apt-get update

sudo apt-get install -y boot-repair && boot-repair

Use 'Recommended repair' option. For more details use this official Ubuntu document.
