UEFI PXE

Hello,

I'm using linux as pxe server. I set up grub2 to boot from pxe uefi but I've got the error 0x0000025 when trying from a WinPe.

I tried wim files from Windows 8 and wdsmgfw.efi.

I think there is a problem in the folder structure and the link between bcd and "boot".efi.

Is there a particular structure for the folder ? and is this case sensitive ?

x64/EFI/boot/

x64/EFI/microsoft/boot/

When booting from an usb key, the mdt works great. It deploys windows 8 without problems.

Thanks.
