Error 0x8024a205 when trying to update to 2004

[HEsse]

The NUC8I7BEH2 is only a few months old and was therefore installed with cleaninstall. So far all updates have been done without any problems.

After selecting "Fix Problem" a window appears with "Check PC" then "Windows 10 cannot be run on this PC".

The reason given is "Windows cannot be installed because this PC has an unsupported disk layout for UEFI firmware".

What can I do to install 2004?

[LeonWaksman]

1. Is the UEFI mode in BIOS enabled?
2. Did you installed Windows with UEFI mode in BIOS enabled?
3. Please attach image of Disk Management.
4. Please check that your System Drive has GPT type partition.

Thanks for the answer.

The systempartition is MBR. UEFI is enabled, as far as I can tell.

[LeonWaksman]

So, now you should convert the partition from MBR to to GPT. Use for this MBR2GPT Microsoft Tool.

Or, during the install (presumably you have booted from Windows installation media that is UEFI enabled), you can delete *all* paritions on the drive and then tell Windows to install to the unallocated space. This forces the creation of a new UEFI partition table and also lets the installer make smart decisions on partition sizes.

Well, thanks for the help.

mbr2gpt does not work. Get the message: "Disk layout validation failed for disk 0"

@n.scott.pearson​ 

Will it also work if the M.2 is deleted and a backup is loaded using Macrium Reflect?

[n_scott_pearson]

No. That would get you whatever partition table type was present when the backup was taken. Since you were booting Legacy previously, this was MBR.

Hi @HEsse​ ,

1. Your Windows wasn't installed correctly. I suggest you to reinstall Windows using the following method (backup your data first):
2. Please prepare your installation media (you need 8GB – 32GB USB stick), using Microsoft Media Creation Tool. This will install version 2004.
3. Your bios should be set to default settings. Enter bios (press F2 during boot) and then press F9 (Y) to set defaults and F10 (Y) to save settings and exit.
4. With the installation media inserted into rear USB slot, power ON your NUC and repeatably press F10 to get Boot Menu.
5. In this menu, choose UEFI option of you Installation media.
6. Follow this tutorial to continue with installation.
7. In para. 8 you may enter Product Key from the Microsoft Distribution you bought or click on the I don't have a product key and Windows will be reactivated automatically, since it was activated on this computer.
8. Skip on para. 13 and continue in para. 14. Important, do not format drive where you want to install Windows, rather delete all existing partitions from this drive, till you see one unallocated space.
9. Press Next and continue with the installation.
