After successfully completing a one-time or continuous virtual export to Hyper-V, the virtual machine will not boot and displays "Boot Failed. EFI SCSI Device." in the console window. Please take note of your Hyper-V export configuration to see if you set up the export as Generation 2 using the disk format VHDX.
Re-run the export wizard and select generation 1 using disk format VHD. Your VM should successfully boot now as generation 1 VMs use PCAT BIOS firmware.
NOTE: This has been tested for supported EFI bootable (Gen 2) machines, exported to Hyper-V 2012 R2 & 2016 and ESXi 5.5 & 6.0 hosts. Supported exports to hosts are dependent on what version of Core is installed. Check product Release Notes to verify what is supported with your build. This work around will not work with a SRP bootable (Gen 1) machine.
