I would like to something about BCDBOOT

[Rbcc56]

While I was on the web trying to get a piece of code to work

for %%i in (A B C D E F G H I J K L M N O P Q R S T U V W X Y Z) do ( if exist "%%i:\fartyname.txt" set usbletter=%%i )

Dism /apply-image /imagefile:%usbletter%:\sources\install.wim /index:6 /ApplyDir:C:\

bcdboot c:\windows /s S: /f all

I keep getting an error that seems to point to the [S:]

https://commandmasters.com/commands/bcdboot-windows/: 

/s S:: Denotes the system partition where the boot files should be installed.

Is this where the boot file are copied or where they are Originated?
/f all: This argument instructs bcdboot to prepare the boot files to support UEFI firmware type.
C:\Windows: Again, this specifies the Windows directory from which to copy the required boot files. Should this be where they are originally [C:\Windows]?

Should the S: Partition be active??

You only use the /s or /f option on GPT disk partition layout. You cannot make a partition active on a GPT disk.

/s is the destination (in MBR disk S: should be active partition)

Yes - it should be the C:\Windows of the windows installation that you want to add to the bootloader

Based on my limited knowledge of GPT (and this alligns with what @Tripredacus said) there is no such thing as active partition for GPT disk

Instead you may have to (or maybe this will be done automatically) make a FAT32 efi partition instead, but I don't know the details about that cause I don't have much experience with GPT disks, so look that up

If using Diskpart, you just make the FAT32 efi partition on a GPT disk. You don't set anything, so I'm guessing Windows (or bcdboot) just works with it as is.

I think Diskpart will actually show an error message if you try to make a partition active on a GPT disk
