I have the same problem with an Dell Inspirion 17 (7737, Type P24E001,
Servicetag 7D4h512).
Booting into Windows works direkt from EFI. (ESC in Grub2 and EXIT in console
brings me back to EFI-Boot Menu). There I can run Windows 8.1 with Secure Boot
on. Also Linux starts with Secure Boot on.
If I turn Secure Boot off I also can boot Win 8 within the Grub Boot Menu. I
also tried #25 with no change.
The error message with Secure Boot on keeps: "cannot load image".
There seems to be a difference in the entry from the chainloader call and the
one from EFI (read by: sudo efibootmgr -v)
in the error message the call was:
filepath
/ACPI(a0341d0,0)/PCI2,1f)/Sata(0,0,0)/HD(1,800,fa000,423835a37539af4a,2,2)/File(\EFI\Microsoft\Boot)/File(bootmgfw.efi)/EndEntrie
EFI(sudo efibootmgr -v):
HD(1,800,fa000,a3353842-3975-4aaf-a6ed-50d49f811889)File(\EFI\Microsoft\Boot\bootmgfw.efi)WINDOWS....
The order of the HD()-entry seems to be mixed up!
Any idea how to fix it, test an other order?
