Check your bios settings, secure boot feature in BIOS should be disabled.

Since you can boot into Ubuntu with commands. Do it, and when you are in Ubuntu:

At first try sudo update-grub and reboot

If no success.
- To find out if you have efi or legacy boot run in terminal:
[ -d /sys/firmware/efi ] && echo "EFI boot on HDD" || echo "Legacy boot on HDD"
- For efi boot:
sudo grub-install --boot-directory="your boot directory" --bootloader-id=ubuntu --target=x86_64-efi --efi-directory="your efi directory"

Example "your boot directory" = /boot and "your efi directory" = /boot/efi
- For Legacy boot:
sudo grub-install sdx
x in sdx being your disc with Ubuntu eg. sda, sdb etc. You can find this out with gparted
- Last
sudo update-grub and reboot
