[SOLVED] Windows Server 2016 Update don't working

Then I see no other option than reinstalling this server from scratch or migrating all the functions to a new one.
 
Yes this is possible.

Or do you need only this?

It seems this VM is configured in an (generation 1) state and not (generation 2) which can virtualise an UEFI-based firmware!

For Gen1 VM (MBR formatted image) is it not common to have an EFI partition. So I don't know what happend before, but I thinks someone has tried to covert it to GPT which is causing the issues.
 
Ok, so what we can do now?

The VM has to be in Gen 2?

Edit:

I have asked which Gen is used

Okay, normally the System Reserved Partition (200MB) (SRP) is set as System, but in this case the (99MB) is set as system. So I would suggest to rebuild the current SRP partition using the following instructions into the Recovery Environment.

These are the steps I have just tested on one of my VM's with Server 2016.
  • Run Diskpart
    list disk
    select disk 0
    list partition
  • Identify the the SRP partition.
    select partition X (Recplace X with the number of the SRP partition)
  • Format the SRP partition
    format fs=NTFS label="System Reserved"
  • Set the SRP Partition as active with the following command
    Active
    (Note that it is marked with an * now, when running list partition)
  • Exit DiskPart and press enter
  • Change the focus from X: (the default) on the SRP partition (c:) by running:
    C:
  • Create a folder called Boot running:
    Mkdir Boot
  • Copy the content of the boot folder on the system partition (X:) to the new folder:
    xcopy X:\windows\system32\boot c:\boot /e /h (replace X:with the correct drive letter which contains the Windows folder).
  • Copy the bootmgr from the root of the ISO (X:\) (replace X: with the correct drive letter of the Server 2016 ISO)
    copy X:\bootmgr
  • Now Run the following commands
    Bootrec /Fixmbr
    Bootrec /Fixboot
    Bootrec /rebuildBCD
  • Press Y when you'll see the message "Add installation too boot list" and press enter.

  • Close the Command Prompt and reboot the server

Should I delete the EFI Partition and then doing the steps?
 
Hi,

I got this information from our provider:

VM Generation 2
Hyper-V Version 9. OS 2019

Okay, then I would suggest to reformat the VHD image as GPT and reinstall this server from scratch. I see not other options how to fix the failed MBR > GPT conversion.
