Title:
  Bootloader was unable to install during a fresh install alongside
  windows 10

Status in grub-installer package in Ubuntu:
  Confirmed

Bug description:
  Before starting installation ubiquity informed me that the installer
  is started in UEFI mode and that I have one or more operating systems
  which are installed in BIOS compatibility mode. If I continue with the
  installation, I might not be able to boot back into the other
  operating system. This warning is there every time I install any linux
  distro and it finishes the installation correctly and after
  installation I am able to boot back into both OSes installed. The
  installation was successful with all the previous versions of ubuntu
  namely 14.04,15.10 but with the latest LTS, the installer crashed
  saying that the bootloader was not installed at the target.

  The funny thing is, I have windows 10 installed which is a modern OS which needs to be installed in UEFI mode so I do not understand  why I am getting the warning in the beginning of the installation In the first place.
  Mine is an HP Pavilion-G6 laptop.

  EDIT:-I forgot to mention one thing that is, my laptop did not ship
  with windows 10 preinstalled. There was previously windows 7 on my
  laptop which might have been installed in Legacy/BIOS compatibility
  mode. I had upgraded windows 7 to windows 10 but did not need to make
  any changes in the BIOS settings to boot to windows 10. I guess
  windows 10 was able to boot in Legacy mode somehow...Strange. But
  nonetheless, I was able to successfully install previous versions of
  ubuntu in the past along side windows 10 installation
