Can someone tell me whether or not it is possible to chainload a non-MS-signed EFI application from the BCD?
I'm attempting to add a GRUB2 EFI build to the BCD, but no matter what I try the bootmgr insists that the application is missing or invalid. Also, it seems to be not possible to chainload a bootsector on an EFI PC - even though you can boot from a USB with that same bootsector.
I can understand the latter (though I would welcome workarounds, if there are any). But why can I not load the GRUB2 EFI application by creating either an application or bootsector app in the BCD w/ the path set to grub2.efi?
grub-mkimage was invoked with -O x86_64-efi
