Convert vhdx to vhd

Hi,

Running Server 2012 R2 

I have a requirement to convert a vhdx to vhd. I used the builtin feature in the hyperv manager to convert the vhdx (Fixed) disk to a vhd (fixed).

When i create a new server an attach this vhd disk, i get an error when the vm boots. It briefly displays the windows logo, then gives an error: boot failure. Reboot and select proper boot device or insert boot media in selected boot device. This occurs whether i attach the disk as ide or scsi.

Why would the converted drive no longer be bootable?

Any help would be greatly appreciated

If the VM was a Generation2 virtual machine, then it is UEFI.  And VHD can only be used with Generation1 virtual machines which are BIOS.

The OS in the VM cannot simply handle the bootloader change between BIOS and UEFI.

That is what I suspect is going on.
