I had Windows 8.1 and updated to 10 for free. I want to dual boot it with Ubuntu 15.04. I made a bootable USB stick. In installation process it shows that I have a Windows 8 OS and does not allow me to install Ubuntu besides my existing Windows 10.

After upgrading to Windows 10 on Acer Aspire-AXC-605, I could not boot into ubuntu and F2 key would not bring up bios screen so could not boot from USB ubuntu live.
I had to use Esc key while booting this brought up a "Diagnose PC" screen and I could boot USB from there.
