Windows 10 cannot upgrade 2004 and the cumulative update

The support in this thread was for 4 days (September 3 - 7).


Solutions were offered in post #56.

OP ended the troubleshooting in post #59 on September 7, 2020.

I'm trying to do the clean install now.

I ran into a problem of "Windows cannot be installed to this disk. the selected disk is of the gpt partition style." I fixed it by reading https://www.easeus.com/partition-master/the-selected-disk-is-of-the-gpt-partition-style.html and doing this:

diskpartlist diskselect disk 3cleanconvert gptexit

So now I could actually select the hard drive to install windows. Then I hit this error: 0x80300024, which I plan to fix by removing the other hard drives How to troubleshoot the error 0x80300024 on Windows 10? - Read Our Articles and Optimize Your PC for Peak PerformanceRead Our Articles and Optimize Your PC for Peak Performance

For removing the other hard drives, is it enough to just remove the data cable from the hard drive? Or do you have to disconnect the cable from the motherboard too? Thanks

Let the Windows installer create the partitions for you.

If you have more than one hard drive, simply disconnect the cable from the drive(s), and label which cable goes to which drive.

What source was used to create the iso?

I forgot which one, it was made when I made the post two months ago. The instructions were from here.

But the way I changed the C drive to GPT was correct right?

If the system uses UEFI, and you are installing Windows on the C drive...correct.

How do I check if my motherboard uses UEFI or old BIOS?

My motherboard is MSI Z270-A Pro (mS-7A71).

BIOS ver: E7A71IMS.170

Does it mean it's BIOS?

MSI Global not sure if BIOS or UEFI?

It supports both.

Boot Mode Select [LEGACY+UEFI]
[LEGACY+UEFI] Enables both Legacy BIOS boot mode and UEFI BIOS boot
mode.

got windows reinstalled, thank you so much guys! The only thing I lost was the firefox and chrome bookmarks. I thought I had copied my entire user folder over to a thumbdrive under ubuntu, but then after reinstallation I realized that user/AppData is missing the Local folder with all the settings. Bummer!
