On which disk is your Windows install and on which disk did you install Ubuntu? @wizardfromoz is probably one of the best people to help you since he has a lot of experience with dual/multi-boots.
Booting Issues

- Start date
Looks like a GRUB misconfig.
You want to open a terminal and run:
Ref here:
[edit: also...]
Change:
GRUB_TIMEOUT_STYLE=hidden
to
GRUB_TIMEOUT_STYLE=menu
[/edit]
Also change this line (IDK if Ubuntu fixed that like Mint did, but it won't hurt):
#GRUB_DISABLE_OS_PROBER=false
so it reads:
GRUB_DISABLE_OS_PROBER=false
And save (Ctrl + o) and exit (Ctrl + x).
Okay, now just
And reboot. Should now give you an OS choice.
You want to open a terminal and run:
sudo nano /etc/default/grubRef here:
@totalnoob - the file /etc/default/grub is one of the key files used by Linux to control how your computer boots up, using certain parameters.
If you open a Terminal and type in and paste the command (does not require sudo)
you can copy and paste the output to here. Best is to copy it to inside the Code Tags

Not where Windows is concerned. I have not used Windows since I removed Windows 7 10 years ago, and have been entirely on Linux since.
@luke11685 the rest of the advice you are getting currently is as good as I could give.

Mint is based on Ubuntu, what @Fanboi mentioned still applies for Ubuntu.

my approach would be first from the terminal run
sudo update-grub,
and let it finish then re-boot,

If you change this file, run 'update-grub' afterwards to update

luke1@luke1-B450-AORUS-ELITE:~$This shows that it detected Windows and it should have added a Windows entry to the Grub menu. Try rebooting your system and see if you have both an Ubunut and Windows boot option.
I did it anyway.

You may need to set the correct boot device in your bious if it's not showing the grub menu with both Ubuntu and Windows.

Depending on your circumstances, you might want to think twice about displaying your password on a youtube video
Yeah, I went ahead and removed that for them.
If they want to, they can put it back - but I want them to know that they'll be sharing their password with the world if they put the video back up.
Thanks for watching the video.
My own selfie stick got broken not so quite long time ago so it was hard to me to record it without visible keyboard anyway I was holding my own smartphone with two hands. You see in some cases you can’t record video without for instance smartphone nowadays…etc. Well I can at least give a try to re-record it once again and upload share a link with to you to anyone right here.

Okay, I see two things: 1. It boots from post screen very fast. 2. You have succeeded.
My guess: Somehow the wrong disk is booting and starting up Ubuntu on the right disk (something like HD0 boots GRUB, GRUB on HD0 boots Ubuntu on HD1 straight from GRUB). Never seen this happen, but there are stranger things and it could very well have been you somehow overwrote the UEFI partition on the Windows disk by mistake.
So...
1. Instead of rebooting, do a full shutdown instead (always -- until resolved)
2. Now call the UEFI boot menu, F12 (I think it's F12, I looked up Aorus mobos)
3. Try booting the first disk / entry.
If this does the same thing, repeat steps 1 & 2, then try the next disk / entry... and so on.
4. When you find the right device / entry, you'll need to open your UEFI settings.
4.1. Power off completely.
4.2. Mash the Del key (again, what the spec sheet says, it may vary)
5. In the menu go to "Boot" and make sure "Option #1" points to the correct disk / entry
6. Disable "Fast Boot" as this can mess with things in general.
If that doesn't work, we'll have to pull up a GRUB console (mashing Shift) and see what's going on. That's a separate post, though. Good luck, let us know.
By saying Reboot did you mean to Power Off… instead of Restart?

when we say re-boot , then yes it means a full power reboot of the whole system, not a re-start which only reinitiates the OS
I did it more or less like the way you told me to do so.
You need to access your motherboard's UEFI/BIOS... If pressing F12 at startup doesn't bring up the boot menu, you may want to check you board's manual. Alternatively, just try and get into the Settings. Again, check the manual if Del doesn't work. What's happening is you're booting straight into the bootloader on HDX and that won't do so well. No matter what changes you make on HDY, if HDX is higher boot priority, only the UEFI/BIOS can change that, and to a more limited degree, the program efibootmgr (not 100% with all boards/configs which is why I suggest you enter the BIOS/UEFI).
Switch on your PC while pressing F12 repeatedly (or whatever they key -- check your manual). Failing that, move straight to trying it with Del (or, again, whatever the manual says).
I did it however I’m still having black screen after doing that.
