EFI boot mui files doesn't work

Hi,

This might seem as a really small issue, but to me and the people using this, it's actually a big deal.

When EFI booting from the Windows 7 64-bit installation DVD, downloaded directly from Microsoft, the boot sector and the boot-loader is in English, where as booting regularly (non-EFI), it's in Danish as it should be.

I've noticed that there is mui files placed in the folder "X:\efi\microsoft\boot\da-dk" and the files are:
bootmgfw.efi.mui
bootmgr.efi.mui
memtest.efi.mui

I've opened these in a hex editor, and I can confirm that they do infact contain the boot messages like "Windows is loading files", in danish. So why aren't they being used?

Another file is X:\efi\microsoft\boot\efisys.bin, which again I've opened in a hex editor, and edited the message "Press any key to boot from CD or DVD....", to danish. But I guess that a true danish version of this file must exist?

So what is going wrong here? Why does the EFI-boot loader ignore the mui files, and where can I find a danish version of efisys.bin?

I've tried to see if I could steal these files from other danish installation medias, but without any luck. The pattern is the same.

Any help is appreciated.
