I am trying to incorporate the Windows recovery disc ISOs into an all-in-one grub recovery disc. I have already included WinXP-PE, Win7PE and Win10PE, plus every conceivable utility and malware removal program that I can find. I decided I wanted to add the Windows recovery discs for all versions to eliminate having to carry a separate flash-drive or disc for Win7, 8 and 10 x86 & x64. I have been able to create the ISOs and run them successfully from the grub menu.

The problem is that the Windows installation is not detected, making it impossible to use system restore. I am able to see the system drive when I click "Load Drivers" (Win7 recovery).

Hopefully someone here can give me a clue.
