You probably dont know anything about this, because you still haven't figured out what is the point.
I mentioned Linux in my first post "efibootmgr alternative" - since efibootmgr is Linux program, and we are on Windows forum its obvious that i want Windows program that can do stuff like efibootmgr does. You have no idea about it.
About laptops blocking messing with uefi boot - its not safeboot but Secure Boot.
Who was talking about laptop? PC in general, is desktop, and even if i had laptop, Secure Boot can be disabled.
I really dont think that bcdboot can be used for "talking to Linux" (thats what you said) i wanted to modify UEFI boot order in NVRAM.
Bcdboot create files needed for booting for both legacy (BIOS) systems as well as UEFI systems. For leagacy, this write BOOTMGR (bootloader since NT 6.x) to PBR of system volume and create other boot files. It works on MBR disks only. For UEFI, it copy windows loader (EFI executable binary) and other needed files to ESP (usually 1st partition, few hundred megs. fat32 formatted) and creates new UEFI boot entry in NVRAM. I think its obvious that these are completely different and incompatible (BIOS/UEFI). UEFI booting is supported on all x64 versions of Windows since Vista.
If you still not got it, Bcdboot can create UEFI boot entry in NVRAM, so its possible to work with it from Windows.
These "linux codes" i send you, arent outdated.
Now i'm asking again, is there any efibootmgr alternative for Windows?
EDIT: leave that thread, really, i dont think that you can help me
