It works ! My winPE starts !

My winPE is not yet ready to support this hardware so I cannot confirm, for the moment, that the whole cloning process is working (but I'm working on it...)

Many thanks !

Nicolas

That's not a message which can be generated by iPXE:

$ git grep EFIIMAGE
image/efi_image.c:              DBGC ( image, "EFIIMAGE %p could not 
identify SNP device\n",
image/efi_image.c:              DBGC ( image, "EFIIMAGE %p could not 
install file protocol: "
image/efi_image.c:              DBGC ( image, "EFIIMAGE %p could not 
install iPXE download "
image/efi_image.c:              DBGC ( image, "EFIIMAGE %p could not 
create device path\n",
image/efi_image.c:              DBGC ( image, "EFIIMAGE %p could not 
create command line\n",
image/efi_image.c:              DBGC ( image, "EFIIMAGE %p could not 
load: %s\n",
image/efi_image.c:              DBGC ( image, "EFIIMAGE %p filling in 
missing DeviceHandle\n",
image/efi_image.c:              DBGC ( image, "EFIIMAGE %p could not 
start (or returned with "
image/efi_image.c:              DBGC ( image, "EFIIMAGE %p could not 
load: %s\n",

I'm assuming the message was "EFIIMAGE 0xb815d048 could not load: Error 
0x7f048182", since you said that it was generated from the "kernel" 
command (rather than the "boot" command), and there should be only one 
possible error message on that code path.

The error is EFI_INVALID_PARAMETER.  It's plausible that the platform 
firmware is complaining about our NULL parameter for DevicePath.  Could 
you try the attached patch, which provides a dummy empty device path?

Thanks,

Michael
