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

Hi, all

I reinstalled windows 10 from DVD to my old HP elitebook 850 G2 in 2015 and I got this message "We couldn't install Windows 10" as photo while I installed it twice.

Why is that? And how could I do it?

My browsers often had been interrupted unintentionally so many times and I couldn't bear it anymore.

Also, my browsers had been installed some embedded plugged-in software like Baidu search, or other search engines, plus popped-up ads sometimes showed up in the browsers from China, because I'd been China for work sometimes.

Hope someone could solve my issue asap.

Sorry, just know photo couldn't be uploaded.

Warning messages as below.

"We couldn't install Windows 10

We've set your PC back to the way it was right before you started installing Windows 10.

0x800F0830 - 0x20003

The installation failed in the SAFE_OS phase with an error during INSTALL_UPDATES operation"

I also couldn't find any related articles by that error code "0x800F0830 - 0x20003" with its Troubleshooting tips.


Thank you very much.

Issue proceeding...
I followed the fix steps written in, 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 (". 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,
(2)Clear SecureBoot Keys
Then I ticked the option on (2)Clear SecureBoot Keys.
By this action it should mean disable SecureBoot on 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 (".

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.

This is another discussion in which no solution was found, but creating a new USB installation media and making a clean installation of Windows is worth analyzing.
