    I would recomend booting back ontot the live USB you used to install ubuntu,

    opening a terminal with these keystrokes: Ctrl+Alt+T and pasting this command into it : 

     sudo add-apt-repository -y ppa:yannubuntu/boot-repair && sudo apt update && sudo apt install -y boot-repair boot-info

    this will fix your dual boot, putting back grub.

    you'll be able to boot into both your windows and your ubuntu

    later if you want to have windows show up first in the list (or any other change/enhancement), you can boot to your ubuntu, open a terminal again and run : 

    sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer

    you can then open grub customizer from your start menu. the rest is pretty intuitive.

    there's mountains of evidence online to back the idea that grub (or systemd or any other) are supperior in every way to windows bootloader, starting with wikipedia :

    1. https://en.wikipedia.org/wiki/Comparison_of_boot_loaders
    2. https://www.quora.com/What-is-the-difference-between-GRUB-and-the-Windows-bootloader
    3. Grub or Windows Bootloader for Dual Boot?
