For several days already I'm trying to update my OS to windows 10. Several showstoppers hit me in my face though.
First the existing OS for upgrade. PC came with dvd's for manufacturer modified bloatware filled windows 7 in either 32 or 64 bit configuration. I'm using the 64 bit version (over 4GB of RAM in use) so it is 4 DVD's load that restores within 4+ hours wiping out entire system's content.
Then you realize that it restored an MBR image. So HDD over 2TiB might be an issue. Change to (U)EFI boot is not trivial but possible.
Then the upgrade to W10. It doesn't work with this modified EFI dual boot mode.
Back to system restore images. Before proceeding it is good to note down w10 serial key. After the bloatware was removed and several hundreds of windows updates were installed (lucky me to have 300 Mbps network connection)... upgrade went well.
But then you think how to set up a clean OS. Microsoft provided a tool to prepare an USB boot drive or DVD. Nowadays USB is the option to use.
Skipping several hardware related issues (HP Elite has custom motherboard with custom power supply and no power for the graphic card - shame on you HP), I have started the USB: press escape during startup, choose boot menu, choose general UDISK 5.0.
Installation went well up to the last step where it showed me a dummy error:
"System Windows nie może zaktualizować konfiguracji rozruchu komputera. Nie można kontynuować instalacji."
Or
"Windows could not update the computer's boot configuration. Installation cannot proceed."
Any idea what to do next to have UEFI based fresh install of Windows 10 preferably with dual boot on HP Elite 8200 CMT?
I'll post updates as it goes by.

Update. My HP 8200 Elite is starting with current configuration (20GB of RAM: stock 2+2 and ballistic sport bls8g3d1609ds1s00.16fer 8+8). However from time to time it fails to boot up. Graphic card sends no signal. Power is on. After several seconds power supply gets its fans onto max speed. I'm afraid that there is some short circuit or alike so that graphic card fails to start and psu goes to immense cooling to provide enough power.
Taking of the memory modules helped.
Officially HP mentioned that elite 8200 supports 4x4GB but for me 2x8GB+2×2GB worked with this small issue
I'm guessing that root cause seems to be something with UEFI or BIOS settings. When starting from an EN boot Windows 10 drive, I cannot modify bcd configuration using defaults - it works however when I specify store location directly.
C:> bcdedit /enum
The boot configuration data store could not be opened.
The volume for a file has been externally altered so that the opened file is no longer valid.
Polish version:
C:> bcdedit /enum
The boot configuration data store could not be opened.

After several more attempts I have managed the following:
1. Running ubuntu and "efibootmgr" (or whatever the command is... I don't remember but it starts with "efi") showing an error in missing "show_boot_order()" function... might be my ubuntu system's error or EFI's corruption.
2. EFI configuration (options on the list) are stored within VRAM - internal BIOS'es (or UEFI's) persistent memory storage. It might hold troian's, rootkits and other malware (including DRM's).
3. Mu EFI boot menu was showing ubuntu several times. This might not be the root cause but for sure is a symptom of an issue.
4. I had corrupted NVRAM content
5. In GPT disk layout there is no MBR (old style disks had reserved "data" at the beginning with "partition table" and "startup code"). Instead you have a special partition called "ESP" which holds the boot applications. Location of those applications are written... within NVRAM.
6. Microsoft has an extra "microsoft reserved" partition - I don't know yet what it is for.
7. Most important. I have managed to install Windows 10 after all. It couldn't deal with corrupted NVRAM. After clearing the RAM (I have tried loading defaults and clearing it using my mobo's button...) multiplicated "ubuntu" options disappeared and Windows 10 installation went fine.
