Hello.
I have slipstreamed a install.wim of Window 7 Enterprise x64 with updates language pack and necessary drivers. That was done within Windows 10, and withe ImageX i applied the install.wim to my D:\ Drive and i ran
Code: 
cdboot D:\Windows
to add windows 7 to the boot list. However, Windows 7 cant boot, it shows an error saying that
Code: 
\Windows\system\winload.efi couldnt have the file signature verified "0x000428".
What can I do? I dont want to mess with my GPT partitions, as i want keep them OEM as long as possible... :D

Win 7 isn't compatible with secure boot. On BIOS, turn it off.
For the installation also turn Fast boot off.

To install Win 7 on a EFI-GPT disk you must boot the Win 7 installation disk as UEFI.
The installation disk must have \efi\boot\bootx64.efi
