So with grub chainload it is not possible to also use initrdefi ?

Just to reiterate here.
* Grub does not provide standard methods for booting efi binaries and initrd but instead does special handling.
* Grub is for disks
* To boot winpe from disk you can use their standard efi bootloader
* wimboot is made to be used with iPXE for network boots

The right tool for the job is to use iPXE + wimboot for networkbooting
And for disk booting it is to use Grub and windows standard boot process to start winpe from disk - which does not involve iPXEs wimboot.
