It is really strange.
After delete the Windows BCD Store it looks better, but not really perfect.
Now, I see the most of my drives to boot... but not in the right order.
Can I disable the synchronization between NUC UEFI and Windows BCD store?
Can you check if your disk is correctly partitioned? Windows 10 shall create the following four partitions during installation:
- Partition 1 - Recovery (450 MB)
- Partition 2 - System - (99MB) The EFI System partition that contains the NTLDR, HAL, Boot.txt, and other files that are needed to boot the system, such as drivers.
- Partition 3 - MSR - (16MB)The Microsoft Reserved (MSR) partition that reserves space on each disk drive for subsequent use by operating system software.
- Partition 4 - Primary - (rest space on SSD) Where Windows is to be installed to.
I use M.2 SSD with 128GB and with Windows 7 x64 UEFI-Boot (GPT).
I see the EFI and the System Partition.
At the moment,
I have a PowerShell script that runs at every boot, that delete the bcdedit /enum firmware entrys.
I think that is a very dirty solution, but at the moment my only solution....
Please read the following: Recommended UEFI-Based Disk-Partition Configurations This article is related to Windows 7 partition. As you can see, in correct partitioned disk you shall have three partitions: System(EFI), MSR and the main partition (Windows). From your post I understand that something is missing.
I have this Apply Images by Using ImageX
And this with the diskpart scripts: Sample: Apply Images on a UEFI-based Computer by Using ImageX
I read this to: UEFI/GPT-based hard drive partitions | Microsoft Docs
There are "only" System (EFI) and the main-partition.
And yes, I have a Recovery-Partition to at the end of my disk.
One Moment, I see, when i use diskpart, I can see the System(EFI), Reserviert(MSR), Primär(Main) and Recovery(Recovery) Partitions.
Only the Windows Disk Management do not show the other Paritions.
Also, I have the recommended Partition layout.
I have tested it without a Recovery Partition, same problem.
The BCD Store saved after every boot the detected disks. When I have a USB Stick with EFI, Harddrive with EFI connected, the BCD Store saved this. After disconnect the USB Stick and Harddrive and reboot Windows, there are still in the BCD store. After that boot I have problems to boot from next USB Drive or what else.
