First Defence ISR and EFI

Using First defenceISR is nice on my computer with Windows 7.
Now with windows 10, i have converted two EMPTY snapshots to windows 10.
No problem. ( i got errors convering "full" windows 7 snapshots)
So building one windows 10 with my prgrs and the other is waiting for use.
But i also have a laptop. On that there was windows 8.1.
So converting it to Windows 10 , gives no problem.
But to day i would using Firtst defence on it. Using boot.exe nt/60 C: gives the message :
it can only use on old PC/ AT systems and not booted with EFI.

How can i solve this problem.

 

The successor Instant Recovery works with 10.

Yes i can change in the bios from EFI to old fashion bios. But i do not know the consequences of this.
I have to study it.
And Instant Recovery ; does it work like First Defence ISR ?
All this i have to study.
