Dual OS PC boots into Windows instead of GRUB

I have already asked this question but have gotten no helpful answer. I recently, for fun, tried to take an old computer, format it, and install a dual OS (Windows 10 Home and Ubuntu 16.04) I successfully got both of them installed and running, but to switch between them, I have to use the device's boot selector instead of Ubuntu's convenient grub interface. It does show, but not on boot-up. See the image below for the exact boot order.
No matter what I do, I can't get it to show grub on boot-up. I've tried changing the EFI within Ubuntu (it resets after restart), changing within Windows (no option), changing from BIOS (no option), reinstalling grub like 3 times (no effect) and everything else. Can someone please help me get grub to show on the first startup?
Here is the output of sudo parted -l:
Model: ATA ST750LM022 HN-M7 (scsi)
Disk /dev/sda: 750GB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt
Disk Flags:
Number Start End Size File system Name Flags
1 1049kB 524MB 523MB ntfs Basic data partition hidden, diag
2 524MB 629MB 105MB fat32 EFI system partition boot, esp
3 629MB 646MB 16.8MB Microsoft reserved partition msftres
4 646MB 393GB 393GB ntfs Basic data partition msftdata
5 393GB 744GB 351GB ext4
6 744GB 750GB 6328MB linux-swap(v1)
I checked, both Windows 10 and Ubuntu 16.04 are in UEFI.
I have tried changing the boot order/file within Windows too, but it does nothing.
Ubuntu doesn't show up as an option within BIOS, just "OS boot manager"
I have disabled hibernate and fast boot within Windows.
Any help would be greatly appreciated. Thanks!
Edit: I FINALLY got boot repair working. http://paste.ubuntu.com/p/hsRxPy4TyH

What brand/model system. Some need work arounds, or booting fallback/hard drive entry, not ubuntu entry in UEFI boot menu. Have you updated UEFI from vendor? All systems need that. Post the link to the Create BootInfo summary report. Is part of Boot-Repair: help.ubuntu.com/community/Boot-Info

Everything? Did you try dropping into an EFI shell and setting the boot order there?

You could boot into Ubuntu and runsudo update-grub, reboot and hope for the best. But as boot-repair did not work, I'm not sure this will either. But it's worth a try. I would read line 963 onwards of your pastebin, particularly lines 977/78. Make sure you read up about about bcdedit first or you could screw up your Windows boot also. Backup your Windows bcd file first, just in case.

just to be sure, do you disable the "Fastboot" mode in the BIOS option? Because it will skip the GRUB and start the default OS (windows)
