If the computer is in UEFI mode boot (not legacy boot) then GRUB shouldn't even appear on-screen, and the computer will immediately boot Windows. Only if the firmware is being told to use the CSM should it do so, and then load and execute the code in the MBR, and thus bring up GRUB BIOS from the PXE installation.

So the question is, does Windows boot if the computer's firmware is set to UEFI boot.
