    I think we are trying to help upgrading an existing Windows 10 installation. Post 10 is recommending completely wiping the disk and doing a clean install which would then require significant effort to reinstall all programs.

    These installation problems are not helped by uninformative Microsoft error messages!

    This should not be confusing:



    Try it and see what happens.
    I went to the trouble of opening the case and disconnecting everything except the drive containing Windows. Result is the same. The upgrade will not install and I get error message "Windows couldn't be installed because this PC has an unsupported disk layout for UEFI firmware."

    I could not agree more! How are we supposed to fix a "problem" when the error message is worded in a confusing way or we do not know what the error message means? Personally I have no idea what the error message means and nor would the average PC user for that matter.

    Yes you are correct, I am not trying to install Windows 10. I already have that installed. I am trying to update (they call it "upgrade") to Version/Build 1511, 10586 of Windows 10.

    Also, having to reach inside your machine and start pulling cables just to install Windows is so "old school" it is laughable. Wasn't Windows 10 supposed to be the most sophisticated and intelligent operating system to date? If so, it should be able to install an update on any PC that already has Windows 10 installed. But this is evidently not the case. The way it is now you can install Windows 10, but you can't update it to a later build. This is beyond a joke! Somewhere the programming has taken a backwards leap.

    Could be you don't have a Microsoft reserved partition (this type of partition is never shown in disk management - it should be between EFI and C where you have unallocated space). You can see it using diskpart.

    From a command prompt enter the commands in red (change the select disk 0 to select disk 1 if required) and post the results.

    Thank you for your reply. The Diskpart image is as follows:

    Are you sure this is a GPT disk? From diskpart enter list disk. There will be a * under the gpt heading if it is like this
    Code:
    DISKPART> list disk
    
      Disk ###  Status         Size     Free     Dyn  Gpt
      --------  -------------  -------  -------  ---  ---
    * Disk 0    Online          113 GB   128 MB        *
      Disk 1    Online           14 GB      0 B
    
    DISKPART>
    The partitions look like GPT / EUFI but there are a couple of problems... If your disk is indeed GPT type then you could make these changes...

    You are missing MSR between partitions 2 and 3. You can create it with diskpart as described here How to recreate a Microsoft Reserved Partition for GPT volumes on AppAssure Agents (137589)

    For you it would be

    diskpart
    select disk 0
    create partition msr offset = 701 (The 701 is 829 from your picture above minus 128)

    You can try the upgrade again at this point.

    The second problem is that your ESP and Recovery are not the correct type. The upgrade may or may not check for this.

    Again from diskpart (selecting the same disk). The correct partition types for WinRE and EFI can be set like this

    select disk 0

    select partition 1
    remove
    set id=de94bba4-06d1-4d40-a16a-bfd50179d6ac override
    gpt attributes=0x8000000000000001

    select partition 2
    remove
    set id=c12a7328-f81f-11d2-ba4b-00a0c93ec93b override

    Sorry but you might have to "dumb things down" a bit, as I have no idea what a GPT disk is?

    Here is the print screen when I list disk.

    Trying your method to create MSR partition I get the following message:

    "MSR and EFI partitions are only supported on GPT disks.
    Convert the selected disk to GPT and try again."

    You do not have a GPT partition table.

    "When you deploy Windows to a UEFI-based device, you must format the hard drive that includes the Windows partition by using a GUID partition table (GPT) file system. Additional drives may use either the GPT or the master boot record (MBR) file format."

    To reinstall windows, you will need to delete all the partitions on your drive, and install on the unallocated drive, that way windows can make its own partitions it needs to run.

    I can't make sense of the above. Post 3 by the OP shows Disk 1 apparently has a UEFI structure. Does MSINFO32 report you booting in a UEFI mode under BIOS mode? You can also use Minitool Parttion Wizard to explore the partitions - Disk 1 should show partition types GPT.

    Open an elevated command prompt and try the command bcdedit /export <yourfilename> (insert your choice of folder/filename). If this command fails, it indicates a problem with the boot configuration which my solution fixed. The integrity of the ESP partition seems fairly critical for Windows 10 to upgrade/install. You could try my boot configuration repair at post 7 - there is nothing to lose but ensure you do a full backup first.

    If you conclude you do have an MBR disk after all, you can use the Partition Wizard function 'Convert MBR Disk to GPT Disk' to convert to the GPT structure. However, I've never used this and don't know how reliable this is. Note Minitool have a bootable version of Partition Wizard which may be safer to use than trying this repair from within Windows.

    I think that the OP has previously changed the disk partition table to MBR (Master Boot Record) and for this reason the ESP partition (300 MB) appears in the partition list.

    One quick way to determine if a disk is GPT partitioned is to use the List Disk command of the "DISKPART" tool under a Command Prompt (may require Administrator rights). Simply enter the commands shown in GREEN below. If any attached disk has been GPT partitioned, an asterisk (*) will appear under the "Gpt" column; as shown in YELLOW for Disk 0 below:
