D is correct. You need to run "bcdboot C:\Windows /s C" (Assuming that Windows is installed on the C drive.

D. bcdboot.exe Right-click Start menu > Run > cmd type: bcdboot /? Bcdboot - Bcd boot file creation and repair tool. The bcdboot.exe command-line tool is used to copy critical boot files to the system partition and to create a new system BCD store.

Diskpart! https://computertechnicians.com.au/fix-bootmgr-is-corrupted-the-system-cannot-boot-in-windows-10/

bcdboot

The answer is: D

This is a trick question and I believe the answer should be D. Just from the question asked, we can tell that they need you to respond D: cause it is firmly stated: Which command should you run from Windows Recovery Environment (WinRE). Plus to fix the BOOTMGR you used bdcboot.exe.

What does the explanation of the answer have to do with the question? The question is how to repair BootMGR, not what step to take first.

Why do you have to give the system partition a letter to run Bcdboot when you can use the Bcdboot command to solve the problem?

What would be the final answer and justification?

C is correct. Before you can use bcdboot you need assign a drive lette with discpart if you boot in repair mode.

So, this question is interesting. You need to repair the system partition. And the question doesn't tell you which command you need to run first. From the following website: https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/bcdboot-command-line-options-techref-di You use Diskpart first to know which drive letter contains the Windows Partition and system partition, but you cannot fix it, you can format it. So, I think the answer should be D. bcdboot.exe Repair the system partition If the system partition has been corrupted, you can use BCDBoot to recreate the system partition files by using new copies of these files from the Windows partition. Boot your PC to a command line. For example, boot to the Windows installation disk and press Shift+F10, or boot to Windows PE (WinPE: Create USB Bootable drive). Use Diskpart to determine which drive letter contains your Windows partition and system partition (diskpart, list vol, exit). Optional: Format your system partition: format (drive letter of your system partition) /q Add a boot entry for your Windows partition: bcdboot D:\Windows Reboot the PC. Windows should appear.

The anwser is right, you have to use diskpart command to assign a letter to efi partition before using bcdboot command.
