I think you can find all the answers here. Installing Ubuntu alongside Windows is not really complicated. Comment in that answer (or send me a private message if it's possible on that forum??) if you need further help.

  • Download and setup a USB drive that runs Ubuntu 16.04
  • Reboot PC then enter BIOS and disable UEFI enabling "legacy" to avoid messing with your Windows 10 bootloader (just let UEFI stay Windows 10)
  • Boot into the USB select "Try Ubuntu"
  • Run GParted and select the right most partition and shrink it making room at the end of the disk. This avoids Windodws not understanding where it's located.
  • Leave the space you want Ubuntu to use Unallocated and exit GParted
  • Run the Ubuntu installer
  • Select "Use Free Space" when installing Ubuntu

Ubuntu will detect Windows 10 and put it into the GRUB bootloader, which will be installed into the free space you created. When you want to use Windows go to your BIOS and flip it back to UEFI boot instead of "legacy" and Windows 10 will show its bootloader.
