OK
diskpart
sel vol 5
assign letter=S
exit
bcdedit /set {bootmgr} device partition=S:
OK, don't worry!!!
We have to do that from an USB-Boot-Stick.
Meanwhile it's midnight here and I need my bed.
So find the way to boot into an Command Prompt from USB.
A Media Creation Tool (MCT) from Microsoft would be good.
Meanwhile you learned how to use the diskpart command. That is all what we need.
And it's really easy.
Good night.
You must have a selection of two times "Windows Boot Manager" in UEFI now. Choose the second so partition 2 gets out of use.
What Volume Z means is this:
diskpart
sel disk 1
sel par 2
assign letter=K
exit
bcdedit /store K:\EFI\Microsoft\Boot\BCD /set {bootmgr} description "W-B-M"
exit
Shutdown and check during next startup if you find
- W-B-M
and
- Windows Boot Manager
somewhere in the BIOS Bootoptions. That is the place where you usually also find the USB-Boot-Option
If you find it, select
Windows Boot Manager
The problem we have is that the BCD-Entry and REG-Entry are different.
Only (!) when you found the 2 different entries from above you can continue
And ONLY means ONLY !
diskpart
sel dis 1
sel par 2
delete partition override
sel par 1
extend
shrink minimum=1025
create partition primary
format quick fs=ntfs label="Recovery"
set id="de94bba4-06d1-4d40-a16a-bfd50179d6ac"
gpt attributes=0x8000000000000001
exit
Otherwise only USB makes sense.
Depending on your USB, it might be necessary to disable Secure Boot first

More than 100 posts and isn't ready yet.
Would have been much easier and faster:
- Create a drive image of drive 1 on an external drive.
- Set BIOS to UEFI mode.
- For safety reasons, detach the power or SATA cable from drive 0 and then do a UEFI- GPT Win 10 Clean install on drive 1.
- Boot from the drive image rescue USB drive and replace the new Win 10 partition on drive 1 with the one on the drive image created above.
- Install Minitool partition and resize the recovery partition to 1G.
Another quick solution:
- Set the recovery environment on C: (reagentc /disable)
- Create a drive image of drive 1 on an external drive.
- Set BIOS to UEFI mode.
- For safety reasons, detach the power or SATA cable from drive 0.
- Boot from the Win 10 USB installation drive, launch diskpart, clean the SSD drive, convert it to GPT and create the 3 partitions:
EFI (fat32 - 100M)
MSR (RAW - 16M)
C: (NTFS all remaining space)
- Boot from the drive image rescue USB drive and replace the new C: partition on drive 1 with the one on the drive image created above.
- Boot from the Win 10 USB installation drive, and install the boot manager on the EFI partition.
- Boot into Windows, launch diskpart, shrink the C: partition in 1G and on the space created, create a Recovery partition.
- Set the recovery environment on the Recovery partition (reagentc /enable)
You should end with a partition layout like below

1. I have not done anything with posts after my last post, saying "goodnight".
2. When I turn off (shut down) the PC, it doesn't shut down, it immediately re-boots to the screen where I enter my password. Does not go through normal start up with motherboard info, etc.
3. The only way I can turn off the PC is to hold the power button down.
run just this command
C:\Windows\System32>shutdown /s /t 0
and this command should bring you straight into BIOS
shutdown.exe /r /fw /t 0
But not all machines support this command
