IPXE exit not lauching BIOS UEFI next boot option

[ghermand]

Hi,

I’m using FOG to try to image dual boot Windows 10/Ubuntu PC. Windows 10 is installed first, partitons sda1 to sda4, and Ubuntu uses partitions sda5 and sda6.

Grub is installed in Ubuntu partition, with Windows 10 default option. In the BIOS, UEFI boot option “Windows boot Manager” path has been modified to “\EFI\ubuntu\grubx64.efi”.

When “Windows boot Manager” is the first boot option in the BIOS, all works fine. But when I modifie the boot order, to have the PXE boot first and the “Windows boot Manager” second, It’s not working.

The IPXE EXIT TYPE is set to REFIND_EXIT, and when there’s no tasks pending, the PC boots directly on Windows 10, because REFIND launch “bootmgfw.efi” instead of booting using the definition of “Windows boot Manager” in the BIOS. All the others EXIT TYPE (SANBOOT, GRUB, EXIT, …) fails with a chainloading error.

Is there a way to have PXE boot exiting to the “Windows Boot Manager” defined in the PC BIOS? Did I miss a configuration file?

Thanks for answers.
