Update from 1909 to 2004 fail for Error 0xc1900209

Hi, this site uses English, so I hope all the data you have uploaded is comprehensible to people using English.

I have OCR'd and translated your second screenshot for you: it reads

Your PC settings are not yet supported in this version of Windows 10. Microsoft is
working to support the settings soon. No action is needed. Windows Update
will automatically offer this version of Windows 10 when these settings are supported.

Clearly this is telling you you need to wait. That's assuming it is a correct and appropriate message, of course.
Your first upload seems to be a xml file:

Please be aware that MS tries to protect users where upgrading is known to be likely to cause them problems.
It is not possible to find out what the particular cause is in a given case.

If you were to try to upgrade manually using a downloaded iso file, it's likely you would receive the same message.

Considering
abrupt down-level failure 0xC1900209
https://answers.microsoft.com/en-us/...a-f32837bdf402

you might want to look at the programs you are running- that suggests trying a clean boot, but you still may have a problem if an incompatible program is installed.

In particular, you might try uninstalling any odd-ball security programs.

Follow your suggestion i post my partitions on C

Hi, that looks as if it's a UEFI installation.

I'm wondering where your 16Mb Reserved partition is...


See e.g.
Recover Deleted System Reserved Partition in Windows 10/8/7 – EaseUS
where e.g. Method 3 may help.

I commented:

If you were to try to upgrade manually using a downloaded (2004) iso file, it's likely you would receive the same message.

Apart from the partition issue, I suggested you could try upgrading after a clean boot.

Resolve your missing 16Mb partition, then try upgrading again.

As ever, before any major change, make sure you have a disk image of all Win 10 partitions, e.g. using Macrium Reflect (free-paid) + large enough external storage, so if something goes dramatically wrong you always have a way back.

The routine and regular use of disk imaging is recommended time and again by tenforums members.

Bear in mind 2004 offers little new, and some have tried it and reverted- others are happy with it. See News section for relevant articles including 'Known and Resolved Issues'.

But there is an app that can do through windows ?

Pardon? Do you mean perhaps - 'Is there a magical easy solution'?

As you seem to be missing a partition, that's a low level problem.

The link I posted I think included recovering a lost partition. I suppose if you were lucky you might try that.

Any idea how it got lost?

Feel free to search for other ways to restore it. E.g. Google

'Restore lost system reserved partition'

'system reserved partition missing'

Post back when you've fixed it - or at least tried. Good luck.

So i try
Rebuild or repair (deleted) system reserved partition via cmd (command prompt)
1. Boot computer with Windows 10 installation media and press Shift + F10;
2. Run the following commands at the command prompt:bootrec /fixmbr + Enter
with succes...
but when i type
bootrec /fixboot + enter ...i receive Access denied

P.S:
I have NVMe M.2 drives
For NVMe M.2 drives, i know that need to boot using UEFI / GPT which requires that 'Windows Boot Manager' be the priority boot device used by Windows.

Remember- make sure you have a full disk image before making changes. Macrium Reflect (free).
If you don't, and end up with problems, you will need to sort them out.
