Hello
After a repair of an unbootable Windows 11 system ( with the command bcdboot i:\Windows /s i: /f all
it seems that now, at the BIOS level, I have 2 boot records that boo to the same Windows !
Is that normal ? Could I suppress one of them ? If the answer is "Yes", how should I proceed ?

Thanks for any help Have a good day

bcdboot i:\Windows /s i: /f all

The command bcdboot i:\Windows /s i: /f all copies both UEFI and BIOS boot files (/f all) from the Windows installation at i:\Windows to the target system partition i: (/s i:) and creates a new Boot Configuration Data (BCD) store there.

BCDBOOT <source> [/s <volume letter> [/f <firmware type>]]

- On a GPT disk, the system partition is the EFI system partition.
- On an MBR disk, the system partition is the active partition on the primary disk, either the System Reserved partition or the Windows partition.

Edit:

The command bcdboot i:\Windows /s i: /f all does not work on a UEFI system.

The following command works on a UEFI system:

bcdboot x:\windows /s z: /f uefi

- replace "x" with the Windows partition letter
- /s z: refers to the EFI partition you assigned previously

Your EaseUS Partition Manager screenshot shows that the disk is configured in RAID mode. Since I am not familiar with RAID-based Windows boot configurations, I cannot reliably advise you further.

Do you mean that the motherboard’s boot menu (Asus F8) shows two Windows Boot Manager entries (that is, two firmware boot entries stored in UEFI NVRAM), or that the Windows boot menu shows two operating systems (entries in the BCD store)?

Its usually safe to delete an OS you don't use. Don't delete anything else if you don't know what you're doing.

Asus motherboard:

You cloned your Windows system SSD to another SSD, and now the UEFI one-time boot menu (F8) shows two Windows Boot Manager entries?

Y es
1) The "source" sy stem on SSD show 2 Boot entries when clicking on F8
2) and of cou rse after the cloning, the "cloned" SSD shows 2 entries

Is there a way to remove the second entry on the "source" SSD ? If "yes", how to proceed ?

Thanks Good evening

ChatGPT:

You can remove the unwanted firmware entry either:
  • from the BIOS/UEFI boot management interface (if Asus exposes a delete option), or
  • from Windows using bcdedit /enum firmware followed by bcdedit /delete {identifier}
Be careful to delete only the duplicate entry.

Edit:

The image shows the Boot Option Priorities screen of an ASRock motherboard.

I do not know whether your Asus motherboard has the "Disabled" option shown in the image.

The OP wants to remove an unwanted UEFI firmware boot entry stored in NVRAM, not a Windows boot menu entry in the BCD store.

GPT Disk Boot Process (UEFI-based booting):

1. UEFI firmware performs the POST (Power-On Self-Test).
2. UEFI checks the system's NVRAM for boot entries.
3. A boot entry (usually named "Windows Boot Manager") points to \EFI\Microsoft\Boot\bootmgfw.efi on the EFI system partition.
4. bootmgfw.efi is the Windows Boot Manager, which loads and reads the Boot Configuration Data (BCD) store from the same EFI system partition.
5. Based on BCD settings, it launches winload.efi, the OS loader for UEFI-based systems, to start Windows.

Thanks for the information
I'm looking at the problem with EasyBCD 2.4 and it seems that (with caution !) could solve the problem and help me to delete the useless entry
I used Windows for a long time but never had this problem - It would be good to have a detailed explanation of the Windows boot mechanism and architecture - May be there is some good explanation somewhere !
Thanks for your time and your patience

I believe that option has been presented several times. 🤷‍♂️ :-)
