I reinstall windows 10 from DVD and I got this message "We couldn't install Windows 10" twice.

Hi,
Issue proceeding...
I followed the fix steps written in minitool.com, and here's the steps I'd done.
But some fixes didn't meet what it wrote.
When I did Fix 1, but the troubleshoot tips guided me to this webpage "Get help with Windows upgrade and installation errors (microsoft.com)". There're no steps on what minitool wrote on that webpage. So I couldn't do Fix 1.

Fix 2: My installed windows 10 was pro already, I just install windows 10 pro again. But this HP 850 was originally with windows 8.

Fix 3: I have 264GB on C drive, and its free space is 156GB.

Fix 4: I'm not so sure I disable Secure Boot or not. I found it on BIOS, not the page it wrote. There's an item in my SecureBoot configuration, and two options below,
(1)SecureBoot
(2)Clear SecureBoot Keys
Then I ticked the option on (2)Clear SecureBoot Keys.
By this action it should mean disable SecureBoot on minitool.com wrote on that article.

Fix 5: run them all.

Fix 6: run it and nothing found, so restart it.

Fix 7: run it as well.

Fix 8: Clean Boot it, but I did it from the webpage showed in "How to perform a clean boot in Windows (microsoft.com)".

Fix 9: I only have windows defender, but disable it in Clean Boot action.

Then I reinstalled a new windows 10 pro again at night, but that error message still showed up again.

What am I missing???

Or finally, can I just directly format my entire system drive on C drive, restart my HP laptop?
Then DVD should drive itself based on my HP BIOS Boot sequence, and install windows 10 afterward?
Because I remember I had experience installed earlier windows version from the beginning.

Thank you for help.
