✅ 【Detail】
If you boot your WinPE drive via UEFI, BCDBOOT will default work with GPT and EFI firmware.
If you boot your WinPE drive via LEGACY, BCDBOOT will default work with MBR and BIOS firmware.

So the reason why you get this error is that an EFI reserved partition is not created when BCDBOOT works with GPT and EFI firmware.

If you are booting non-EFI to a GPT drive, you should run this command:
bcdboot C:\Windows /s S: /f EFI

Where C: means Windows partition and S: is the EFI partition.
Conversely, if you are booting Legacy to MBR drive, you should use this command.
bcdboot C:\Windows /s S: /f BIOS

Where S: in this case is the system partition.
If you are not sure whether the computer is UEFI support or LEGACY support, you can try this command:
bcdboot C:\windows /s S: /f ALL

Where ALL means copy both the BIOS and UEFI files to the disk.

Maybe some users are not familiar with CMD and looking for an easier way, you can totally achieve it with the help of a professional tool to save time and effort.
